You made the rocker arm and lifter look very simple to remove and reinstall. Sometimes I like to work on my own vehicle, dealerships rates are outrageous. Thanks
yeah, they are easy to replace, the hard part is getting the valve covers off with all the wiring and hoses that are in the way.
With that motor, the oil journals where the oil comes from to the lifter gets plugged not getting enough oil to the lifter. It's not usually the lifter. Take lifter out. Crank over the motor to blow out the oil journals that are plugged. You will know when the oil squirts and hits the hood so best put a rag over it. Only takes a crank or two to unplug them. Replace the lifter or use a new one. Works every time. It took me 4 times taking mine apart to figure it out with new lifters.
I'm sending my kids dad a screenshot of your reply... Smdh poor dude... They getting him for a whole motor 😩😂 I'm in another state or I'd prove a whole point 😂🥰
How do I krank over the motor? If it's all taken apart?
@@machetesulaco Why would you take it "all " apart? Just take off the valve covers and pull the lifter out that isn't working. You don't want to start it until you get it back together
@@machetesulaco turn harmonic balancer using its bolt
These are OHC engines, so they don't have "lifters". They're hydraulic valve lash adjusters.
I have an 09 Dodge Ram 1500 with 330,000 miles on it. I have used full synthetic oil since day one. The lifters started ticking about 10,000 miles ago but I am now finally able to dedicate the time to do this job as this has been my main vehicle and I couldn't afford to let it sit for too long. I hope to get another 50 to 60 thousand miles before I finally trade it off. I've not had to do anything major to the engine, just a couple sets of plugs, a sepentine belt and tensioner, and 3 water pumps. I also had to replace the radiator at about 200k miles. Along with the lifters, I'm replacing the complete timing set, spark plugs and wires, valve cover gaskets, heater hoses, upper and lower radiator hoses and water pump. Maybe I'm sinking too much time and money into something with this many miles, but this has been one of the most trouble-free vehicles I have ever owned, and I have definitely gotten my money's worth on this pickup.
You fix it?
Word.
I just got done doing my lifter on a 2002 dodge ram 1500 4.7 i removed air intake, wire harnesses, radiator hose, disconnected the battery, removed master cylinder from brake drum,and removed brake drum in preparation for this project. Everything went well except the parts store sent a wrong part in place of one of the lifters. i had to go back to the store get the right one and soak in oil for another 12 hours(i cheated and soaked for 8 so i could have it done that day). I used his advice through the whole project and it went well. 2 thumbs up!!! thank for taking your time spent making this video.
We bought a 04 Durango with the 4.7, I have the 4.7 in my 04 Ram as well. My Ram runs like a dream, has slight noise on startup but goes away within seconds. It has 201k on it, I got it with 165k. Previously it was a state owned vehicle so had regular maintenance. The Durango on the other hand has about 155k, has significant noise that does not go away. I know these motors are notorious for valvetrain noise due to the valve adjusters getting plugged with crap, but didn’t know how hard it would be to repair. After watching this video I am confident that I can get the job done myself. Thanks for the video, to the point and not a lot of irrelevant talking.
Always change your oil on time with full synthetic and try not to constantly romp on the accelerator and you're golden. I have an 03 Durango with the 4.7 and it has been a very reliable engine. 171,000 miles. I've had it for 4 years and the only things I've had to replace were the radiator and the alternator. Now the front end is another story, but that's a just Dodge thing 😂
thank you martin , your knowledge is very helpful, i just bought a 4.7 WG and love it to bits. all your videos are professional. cheers
Thanks Martin for posting this video. My 01 WJ 4.7 had a valve seat come loose about a month ago and I took the heads off and had the machine shop replace all the valve seats. They had a way to install them so that they won't come off again. Well I put the engine back together and it ran great for a few days. Then this morning I went to start it and it made a loud tapping sound followed by an engine miss and a p0303 engine miss code. I had a hunch that a rocker came off and pulled the driver's side valve cover off and there it was. The exhaust rocker fell off. Bought a new lifter for about $13 and popped in like you did and it runs great again. The previous owner wasn't too good about doing regular oil changes and so there was a fair amount of sludge in the engine. I dropped the oil pan and clean the pick up tube and screen as well to be safe. So far so good. Thanks again! Very helpful video.
I'm glad everything worked out for you. You may want to try some Rislone engine treatment to clean out that sludge.
I remember reading someplace awhile back that another problem with these engines is carbon on the valve stems. Supposedly if enough carbon builds on the valve and causes it to stick for even like a fraction of a second, the rocker arm will fall out .
Great video Sir !!
Very helpful .
I want to point out to others how clean the interior of that engine is . This is why you change your oil on a regular basis using quality synthetic oils and filters !
Thumbs up !!!
Say Bruh, thank you very much. I thought that I was going to have to, pass out, wake up, and still have to deal with this problem. But then I see you. Smooth, direct, straight to the point. Now I got it. Again, THANKS BRUH. Much Love For You
I'm glad you liked it and found it helpful. Thank you for watching.
You sir, have made my day. I was just about to buy the tool and was worried about lead time on it (plus the price). I already have a 10mm brake line wrench ready to volunteer. Thanks again.
if that wrench doesn't work for you, Autozone has a set of distributor wrenches that will work. Even a pair of needle-nose pliers with the angled tip would work.
Thank you for taking the time to make this video and explain everything in detail, I'll be replacing my lifters next weekend and it's nice to know it won't be a 3 day event.
You're welcome, the hard part is getting the valve covers off due to all the hoses and wiring harness that run over top of the covers. Once you got them off I think it's pretty easy to change out the lifters
@@martinbuilt ok that's good to know. I'm hoping replacing the lifters will rid the light color smoke during start up and the engine tick. It goes away after a few minutes but it's definitely bugging me
@@somanynamesilltrythis0180 you didn't mention the light colored smoke on Startup that sounds more like valve guide seals. Now the tick noise your hearing is the lifters. I just recently did a video where I install the 08 camshafts new valve springs, retainers and valve guide seals you may want to check that out.
Number is gasquet
Hey man great video I had purchased a 02 Durango and it has a bad lifter and I just found 3 rockers not connected like they fell off but just saw this video it’s going to help so much better but when I installed the rocker I accidentally loosened the bolts to crank but tighten it back up and it drove good after
thank you for your video i just replaced the lifters in my 2002 jeep liberty 3.7l i used a 10 mm wrench , bent the end and grinded on it to make it thinner, it popped the rocker right out just like you showed. and used a small pry bar and a flat screw driver to pop the rocker back in. thank you very much for sharing your knoledge.
Easy as pie, thanks for your video. Your right keep oil clean, like any engine.
Hey, Martin - the "crafted" 10mm worked BETTER than the Dodge tool! Thanks for posting this vid. Everything worked better than I expected.
Your welcome, sometimes the simplest tools are the best.
I’m doing this right now on my long weekend . I underestimated getting driver side valve cover off .. it’s a pain in the rear end . But anyways I just wanted to say thank your all the videos that you do . I watched your timing chain video an handful of times before I did mine on my dodge .
I'm glad you find the content helpful. Thank you for watching.
Thank you for hosting this video I have to say you removed with it the intimidation out of me to do this. My jeep Liberty with over 300k miles I'm suspecting a lifter got stuck and one of the rockers got knocked over.
I saw a video with ame symptoms as mine and I sure hope that's what it is.
Have used synthetic oil but last year or so services have been at over 6600 mile if not more.
I regreat it now but the damage is done.
I'm glad to hear the video gives you the confidence to do this yourself. My 01 Dodge Dakota recently passed the 300K mark several months ago. It also has a lash adjuster ticking.
I want to give credit where credit is due. I had an extra 10m wrench and bent it in the vise to look like what you had and it worked great!! I used it 100% to remove lifters and 90% of the time to install, at times would have to use a screwdriver to install. I installed 16 lifters got them from Napa, Sealed Power lifters $240 job took about 15hrs ( I took my time and I don't do this as a profession) I reused the OEM valve cover gaskets they looked good and are installed and not leaking. I removed the water reservoir. The right valve cover I loosen the air conditioner condenser on the firewall, I removed the oil pickup and the air conditioner and moved it to the side to give me clearance to remove the valve cover. I soaked the lifters for 30 min in 5-30w and installed lifters and turned over the engine with socket wrench on the flywheel to ensure lifter lob was not depressed. Drove the truck for the past few days and runs great. Thx again for this video
rlarson3232
That's awesome glad everything worked out for you.
I forgot to say this was a 2001 Dodge Dakota
When I did the HO cam install I had to move many of the same things that you did. Thanks for posting your comments.
Were you working on 4.7
2014 Dodger Durango 3.6L.... worked perfect!! Thanks for the post. Hardest part was getting everything else taken off to get to it.
Your welcome, yeah there is a lot of stuff that needs to be moved just to get the valve cover off.
The 3.6 is a completely different engine.
martin i love the cadence and the way you relay information to the audience keep up the good work.
Martin you just set me on fire! Mad props!
Thanks

Great video. Very useful info. Not having to take the camshafts out to replace the rockers or the lifters 👍👍👍
Thank you. I'm glad you liked it and found it helpful.😎👍
excelente amigo. muchas gracias por tu trabajo y por enseñarnos. saludos desde venezuela
Sometimes I miss that ol’ 04 WJ overland I had. It was my first V8 and even though I’d laugh at it now, that thing felt lightning quick after owning my 08 JKUR for nearly 5 years. Lol! Great video!
Maybe not actually lightning quick, but the 4.7 HO’s are definitely not slow. Certainly a lot more power than a JK. Rented a JKU for a week on vacation and I liked the Jeep but missed my 4.7… 😁
@@TireSlayer55 Oh it was by no means "lightning quick" lol. Just in comparison to my old, lifted 2008 JKUR on 34" tires it was. czcams.com/video/vDH8IbQZziU/video.html
@@TireSlayer55 for comparison, this was my 2004 WJ H.O. 4.7 (on 32" tires and 2" lift) czcams.com/video/H5o-HEdtSrM/video.html
I feel like the V8 WJ’s are pretty peppy for a big heavy luxury SUV that was designed primarily for comfort and off road ability. Mine’s just the standard output 4.7L and it’s on 31” tires… while I wouldn’t call it fast per se it’s got enough power to make a fun daily driver. Most of my driving is between 0-45 MPH so I’m happy just being able to easily get ahead of slower traffic without needing to give it a ton of throttle. I hardly ever rev it over 3500 RPM in normal driving, but the few times I’ve ever given it over 3/4 throttle it’s surprised me. Compared to the two high mileage 4.0L XJ Cherokees I daily drove previously, the WJ feels like a rocket, lol. I did do the torque management wire snip and a TransGo shift kit which definitely made it feel more responsive in everyday driving.
@@TireSlayer55 Nice! Yeah, those are the same reasons I loved my WJ. I actually had my 2008 JKUR for 4.5 years and then downgraded to the 04 WJ Overland because of a job loss AND I secretely wanted V8 power in a solid axle Jeep! It was my first V8 in any vehicle I had owned and I absolutely loved it for what it was! I had a makeshift 2.5" lift from using the "Upcountry Springs" (a mopar accessory for those models) and a 2" Rusty's spacer lift. For shocks, a buddy of mine helped me fab some used JK Rubicon shock take offs to work with the WJ, and that thing handled and rode phenomenal! My dream now is to get a Rubicon 392 which is what I think the best of both worlds (muscle car and Jeep rock crawling). But man I sure did love that thing! Sometimes I wish I still had it! czcams.com/video/zjHuxnN-m3E/video.html
Thank you for that sir...makes it easier than I thought it was going to be. Love it!🙌
you are welcome, you'll find getting the valve cover off is the hardest part of this job.
Great video, very informative and your video quality really makes it easy to see what needs to be done to get the rocker off and back on. I have a 06 dakota I picked up. It needs valve cover gasket a but think I will tackle this as well while in there. Thank you for posting.
Glad you enjoyed it!
@@martinbuiltyou have quite the pool of knowledge for these motors. Would you recommend using a product like liquimoly engine flush on these motors? Considering doing so on my new to me 06 dakota with 160k miles before tackling valve cover gasket and new lifters.
I was also taught that having your Jeep WJ run hot (210°F+) on the 4.7L causes the lifters to stick or fail = thousands in repairs.
I have altered my cooling system from a hydrolic fan to a Viscous clutch fan with upgraded plastic 11 blade Ford 5.9L fan with slight modifications to clutch face and fan blade bolt holes.
I only have an additional 6lbs on the water pump and that causes under 2MPG/3HP loss.
Ive been doing fine without the fan shroud with my clutch fan and small E-Fan combo. 12.5" Spal fan that is rated at 2800-CFM and the Severe Duty Clutch fan has over 3650CFM according to my Anemometer
Thank you sir! I’m working on my dads 2004 Jeep Grand Cherokee Overlander, easy to understand and helpful. Much appreciated!😎
Thank you I really appreciate that i'm glad you liked it and found it helpful.
Gonna do this on my 00 4.7 Dakota been lifter ticking whole 3yrs owned it 8k miles gonna hopefully do it and be warm out
thank you so very much., great video from mexico.
1st time I see your video you explain so much easy to understand thanks
Glad it helped!
I just ordered the set of lifters you have posted in the description, I have been using 10w30 Pennzoil ultra Platinum full synthetic because here in Texas I was told to run thicker oil from the high heat temps, so I will prime my new lifters that I have coming in 10w30 for 24 hours before I install, do y'all think its a good choice using 10w30 when I see Martin using 5w30? Any thoughts?????
Great technique,almost every video on CZcams shows having to remove or loosen camshaft bolts in order to accomplish this, hope I can do it this way on my 2016 Dodge Charger 3.6.
Hi Mateollios: did you accomplish this way on your charger? I am going to start tomorrow on my 2012 Pentastar V6. Thanks a lot
@@jasonl7025
Hello,
I also have a 3.6 pentastar 2012 and I was just wondering if you were able to do this and was it difficult to do or is it just best to take it to a mechanic?
@@malve308 Hi Jorge: I did open my left valve cover as it is in the front and easily accessible. however I was not able to rotate my engine through the nut on harmonic balancer. Though I used a 25" break bar and could not rotate anything. Maybe I did not use enough force. Anyhow I don't want to apply too much force either. At the end, I used T30 bit to loose camshaft away from cam phaser and checked my rocker arms. I never touched the two T30 next to cam phaser. I would say if the bad rocker arms are away from cam phaser. It is doable and just be patient. If you want to replace rocker arm next to cam phaser. You would need the special tool or a good mechanic. Good luck. If you can rotate engine, it would be much easier.
Gearsoft is it possible to turn the engine key in order to turn the camshaft to the desired position ?
@@Miguelgarcia888 Yes. You can check this video out. czcams.com/video/5zSjArepmfw/video.html. I am not an mechanic and not sure whether it is safe
2008 jeep Liberty 3.7 puting in timing chain got at tdc drivers cam went on pretty easily passenger side seems like it's fair amount of from where it should be. any ideas of what I am doing wrong
Does this work on any engine? I have a 4B1 (Mitsubishi lancer) and need to replace the lifters. I don’t want to pull everything apart for me to have to take the cam shafts off and mess the timing up
Also I have read stories where engine flush gets rid of the ticking sound (some times) and other stories where they tried everything including lifter replacement, and the noise still wouldn't go away.
I'm having that problem!
Question please; I need to rotate the cam (on that same L.H. head as in video), because I'm about to put on timing sprocket and chain, but realized I'd run the valves into a piston. I do know cylinder #1 is @ TDC, so would I be ok with only removing #1 intake and exhaust rockers? I'd figure so since the other pistons are recessed. Thanks
Great video. Short, sweet & to the point.
Thank you 😊
I'm glad you liked it 👍
i just bought new "melling" lifters, but some of them are firm and some are squishy. Is that a problem? (maybe the squishy ones will pump up when i run it the first time?) worried i got some defective ones...
if a Dodge engine tosses a rocker arm, you need to change the VALVE SPRING, in addition to the lifter- not just the lifter. the clearance comes from the spring being weak, not following the cam profile tightly and clearance opening up. if you put spacers under the lifter, you will only collapse the spring more and more, and eventually break the spring. change the lifter and spring, it will run fine and not lose rockers.
My 4.7 currently sounds like a duramax when you cold start it with all the ticking, this might have just given me the boost to go change the lifters and rockers. Thank you!
That would have me very concerned. It also could be the hydraulic timing chain tensioners that are making all the noise.
@@martinbuilt I'll change out the lifters and rockers and see where that gets me. If it keeps it up I'll change the tensioners. I don't think the previous owner of it was very good on maintenance so I've kind of had to just run through everything on that motor.
@@gdcatalyst7812 Yeah oil changes intervals are important with this engine.
@@martinbuilt just installed all new lifters and rockers and the tick remains. It goes away as soon as I'm up to temp though, you could be right it could be the chain tensioners
Great video, thank you sir!!
I have a 2006 jeep commander and can't get to the back of engine to get the lifters or anything off, including taking the head off? Recommendations??
Coming back to you for your thoughts. Replaced rockers, lifters, and timing set. Still clacking like it’s the lifters... got rid of the initial start up rattle from the chain but after a second of the engine running the clacks come on until it warms up.
did you replace the hydraulic tensioners when you did the timing chain set?
@@martinbuilt yes. Everything but the gears. The chains used to rattle like hell when the engine first kicked over. Now it’s quiet for a couple seconds until it sounds like the rockers are tapping around.
thanks great video saved me some cash
So if the cam shaft is in the wrong place? Do we still change it? Or is there a way to move it before you put it back together?
Awesome Video....Very detailed and great knowledge
Thank you, I appreciate that.
Спасибо большое. Нам в России очень помогает ваша информация.
I’m giving you a thumb up for showing how to remove the fulcrum and lifter but I wanna see the crap you go through to get to that point. i.e. All the top stuff you removed to get to that point etc.
Changing the lifters on my 09 dodge journey sxt fwd here soon.. Any best tips to make that go smoothly would be much appreciated. No knowledge outside of this video.. With having my mechanic deal with my engine it's always nerve racking, but I have faith in his abilities! He's a wonderful mechanic!
I looked into that and it's not the lifters on that engine that cause the noise. The rocker arm assemblies need to be replaced. Here is a video that explains the problem and fix. czcams.com/video/jEnErTFhuDU/video.html

Hi Martinbuilt great informative video! Kinda new to this have a couple of questions... should I remove the fan shroud before trying to turn the harmonic balancer to release a couple of valves and which way do I rotate it standing in front of the engine clockwise or counterclockwise? Thanks for your help!
Clockwise is best. I have turned it counterclockwise before with no problem. On my particular model I did not have to remove the hydraulic cooling fan as this is what is equipped on my 04 Jeep Grand Cherokee. If there is not the room from above I would try from underneath you may need some help, someone to watch the camshaft lobe.
I have a 2003 Jeep liberty 3.7l V6. Engine seems to have a knocking sound when car gets to its operating temperature. I can hear it when idling mostly. Doing research on this just in case. Prior owners didn't keep any record of maintainace. But car seems to run fine.
I followed your video of putting the rocker arm back on and it seems to lightly snap on. You have to use a screwdriver to pop it off. I changed the lifter too. It doesn't snap back on like your video...I've been at it all day. It's cylinder 8..the very last rocker arm.
Awesome Video thank you
I'm glad you enjoyed it
Do you have a link to the solid lifters you used
Thanks Martin!
Martin,
I could not find the video where you talk about adding rislone oil treatment to your oil. Which product do you use to help reduce the tapping noise from the valves? Thanks Merry Christmas & Happy New Year!
It was in this video. czcams.com/video/CUjXb7f_pEU/video.html Merry Christmas & a Happy New Year to you and yours!
Excellent! Thank u my friend......
I'm glad you liked it and found it helpful.
Had lifter knock from 120k currently at 187k now and I use ristlone and it has helped with the knocking... truck will make it 300k probably with all original internals
Yeah I like Rislone it does work.
Great video as always. Quick question if you have one bad lifter should you just replace the one or replace all of them?
On the grand Cherokee if you're replacing the one on the passenger side I would replace all of them because of the difficulty of removing the valve cover if it's on the driver's side which is not too bad and you know which one it is I think I might just replace just the 1.
Can you clean a lifter to get it to work again?
Thanks Martin. I need to replace my lifters.I have 195,000 mi.on my 4.7L and it has the original lifters in it.
Dan Hambrick
Hi Dan, changing out the lifters themselves not a bad job it's getting that right side valve cover off you'll find the hardest part of the whole thing. With wiring heater hoses and air conditioning lines not to mention the battery and battery tray all in the way
What was your reason for going to solid lifters? Are those the stock cams?
People !!!! make sure you use Marvel Mystery Oil with your oil change 4qt oil & 1qt mmo
@@martinbuilt any tips on moving the ac condenser and computer harness wires? Your right what a pain.
@@justinthompson2133 Do you mean the A/C compressor? I would unbolt, leaving the line hooked up and move it to the top of the radiator. Remove the transmission control unit. Unplug the injector, and coils and unplug the 2 connectors the right (when facing it) side of the ECM move these wires to to center of the engine.
Hello i let my wife drive my 2002 doge ram 1500 4.7L . She let it overheat due to a bad thermostat. It got into the red and blew all the water out and cut off on its own. It still runs and no water in the oil. But i had a diagnostic test run with a OBD 3 reader. The codes came back as misfire in cylinder 8 , cranckshaft postion sensor. Air temperature sensor and a evaporative code. Anyways i change all the coil packs and spark plugs and crankshaft position sensor and air temperature sensor. It ran great for a day or two. So i had another test on it and its still showing misfire in cylinder 8. And air temperature sensor code. Some people say that the lifter and rocker arm probably fell out inside the valve cover. Is this a problem that occurs alot with these engines. My truck starts and runs but it has a slight tick and it runs a little rough when starting. But it does still run. Do you suggest i take the valve cover off and check to see if something inside is messed up?
Thanks for sharing this would turning the engine from the harmonic balance with the 21mm socket need timing adjustments after thanks in advance
No this does not affect timing, just make sure to only rotate the engine clockwise. Rotating the engine counterclockwise can cause timing chain guide tensioner failure.
great video
Ey Martín thank u so much
Thank you for this video.
I'm glad you found it helpful.
Hi martin , thanks for your videos. Would a new set of melling lifters be a reliable replacement to the factory lifters?
Yes, I would think that would be a good Factory replacement.
Hi, I need some help. my cherokee wj 2000, has a fault. When putting it in the driver position, especially on a light climb, the transmission fails or disengages the power to the wheels. It seems to be low transmission fluid, but I left it above the level and it continues to have this fault. on the scanner does not fail. I ask, could the filter be clogged? I noticed that after hot the fault practically disappears? Thanks..
I would maybe try a fluid and filter change 1st there is a spin on filter inside the 45RFE and 545RFE transmissions. That have the 4.7L engine..
I got the same issue at dodge Durango 2005 4.7
This guy has some massive balls. Look how he doesn't have anything covering the timing chain. If I did this the pennys in my pants pocket would fall into the engine.
Hey Martin, what would you recommend I do if I dropped a small bolt down the oil drain within the camshaft case? Right under the rocker.
I don't think it's going to hurt anything. Most liking sitting on the bottom of the oil pan.
You could try to use a magnet through the drain plug to see if you could retrieve it.
The bore scope that I have has a magnet attachment that would work well.
here is the video on that.

mine starts up no noise but after about 30 seconds then it will start making noise , is that strange
Martin, can you explain how does the lifter actually get oil to it. I'm wondering if there are oil channels going to the lifter that could be clogged. I have terrible lifter ticking all the time. Have replaced all lifters and still the ticking. Is worse when it's very cold out (michigan) but yet after an hour of driving it's still ticking very loud. Every mechanic that has check it out (2004 dakota 4.7) has said it's lifters ticking. What do you think??
Yes, there is an oil galley. It is possible that they are clogged. One way to check is to remove the lifters (lash adjusters) and plug the spark plugs. Rotate the engine over with the starter until you that oil is coming out of all the lifter bosses. This will force any blockage out.
Dood, Thanks ! ! You Rock ! !
My rocker arm just slides in I know it should go in with tension what could it be ? It's cylinder #8 on a 03 dodge ram 4.7... thanks
You may have a broken valve Spring but unfortunately most likely you have a dropped valve seat and the cylinder head will either need to be replaced or fixed.
Great video man thank you.
What brand lifter and rockers are you using getting ready to buy the parts and want to insure i get it done right the first time.
I am running the solid lifters (lash adjusters) from Airram.com and the rockers from a 2005 or newer 4.7/3.7
The solid lash adjusters are a lot of work to adjust the first time but I like them, or I would recommend Millings
Do you need to preload new lifters with oil before installing them? Also any videos on bench rebuild of cylinder head?
Yes soak the lifters in motor oil to work out any air.
No I don't have any videos on that.
Thank you for watching 🙂
Nice video
Hi Martin, do you need all the items you listed in your description? I see that you have 3 different gasket sets listed, just curious (I am new to working on engines). Also, do I need to get that single seal power valve lifter or can I just get the set of the lifters?
I may list several different valve cover gaskets because they changed From magnesium to plastic. You can get whichever brand lifter you like, Thanks for watching.
Hi Martin, is there a way to test the hydraulic lifter if it is bad by moving the tip up and down? Most of my lifters have tips that can move up and down by hand, but two are solid. A tow truck driver told me the ones that move are bad, but idk which ones are causing the tapping at start-up.
Yes, when I swapped out my camshafts all the lifters had no movement and I did not have any lifter noise whatsoever. I would say he is correct if they easily move up and down where you can plunge the tip those are most likely bad
Nice video..
