$200 454 Engine Rebuild: Lapping Damaged Valves, Cylinder Head Cleaning and Reassembly (Ep.20)
Vložit
- čas přidán 29. 05. 2021
- The valves from our cheap Craigslist engine are pretty rusted, and in the last episode we got them clean enough to see just how bad they are. This time, we will get the cylinder heads cleaned up and extensively lap the valves to their seats in an attempt to produce nice, clean sealing surfaces from our rust pitted ones. It is not the best approach, to be sure, but hopefully it is enough to get this engine roaring to life in a future episode.
Dates of filming: February 13th, 2020 (Cylinder Head Initial Cleaning)
April 15th, 2020 (Valve Lapping)
April 19th, 2020 (Final Cleaning and Reassembly)

I understand the allure of using “everything” on an Utube video engine rebuild...but changing a valve or two and replacing old valve springs would not kill the sprit of the work/video.
I agree. No use in ruining the engine.
Then you end up with the problem with springs that are stiffer than the rest
I'm glad he's doing a budget build without buying stuff
I can agree too, budget is great but it will be more of a budget if the rest of the engine doesn't work from one valve dropping or breaking.
@@benjamintaft3680 You understand that the engine is a 454 and not an LS9
@@gvi341984 Would it not still cause damage?
There’s a lot of hoping and praying in this series
I hope you're praying for it to work
And lots of hard work too.

Dude I don’t think anyone would’ve faulted you for buying one brand new valve.
ONE??? Is that some sort of euphemism for 16?
I've been in his shoes before, not with car projects but just with other things in life. It's not about if someone would fault you for it, it's about "I said I wasn't gonna buy new ones and damnit I'm not gonna buy new ones."
I've been there before😂 can't say for sure, but I don't think there is going to be any changing his mind.
I guess sometimes it’s the challenge of it all. Plus, anyone would probably just go buy new stuff. I would. But would that keep someone viewing? “Tune in next week to see if it really works!”
@@trevorvanbremen4718 went to a shop once and said I need a rebuild? They said how far you want to go?😯
@@wdblackman I was in this situation I ended up with little valve head margin after machining on a lathe, instead of risking burning thin faced valves in a new engine I replace them with new ones cheap insurance and saves trouble just in case
I always love the statement "this isn't something I have had a problem with" usually on this channel that is followed later in the video or another one with problems
Maybe I should add "haven't had a problem with YET" lol
#1, I love your videos. Look forward to them. #2, As a Machinist, your “thread chasing” technique gives me unbelievable anxiety.
You do you my friend!
Exactly. He should be using an air impact for any threading work.
Jokes
I will admit, the 1/2 impact is not the way to go for thread chasing haha. Not sure why I was using it for this, probably something related to laziness. I would much more careful to make sure the threads were clean beforehand and that I didn't snap a chaser on aluminum parts or someone else's stuff.
@@FuzzyDiceProjectsHey if it’s good enough for Sloppymechanics, it’s good enough for me.
Hahah mild anxiety yes
@@FuzzyDiceProjects post another video please I'm dying.....not physically tho lol
I'm no mechanic, But that extra-lap'd valve seems like its going to be a problem.
to me , the valve seats are ruined, lapping is good to make a light cleaning or a final fitment on a freshly machined valve and seat to confirm the contact and usually not more pronounced than 1 minute for each valve.
Normaly hand milling the seat and throw the valve in the trash and lap and new one.
If he ground that step down,it would flow much better but might be a bit sketchy..realistically a new valve wouldve been far more smart while its apart
You're definitely not a mechanic because it will be perfectly fine lol
@@jonathanlawson4667 if everyone in these comments was a light bulb in a porch, you’d be burned out 😂
This ain’t gonna be a 1000 horse bbc but I’m damn curious to see what kind of power it does make
@Mike Studmuffin lmao
@Mike Studmuffin I'm dead 💀
I'll be interested to hear the firing order... My guess is something like 1-miss-miss-miss-miss-2-miss-miss
Also, I suggest totally avoiding any form of compression test or leakdown test
Anything over 300hp would be a miracle
@@newcomerjason7791 wrong
Seriously? It’s like $10 or $15 to replace that single valve.
True
What's your point?
I think I get it. It's like a Cuban rebuild, work with what you've got type deal.
I mean, those cars do drive. If it's stupid but it's working...
Coming from someone who loves keeping things as "original" as I can, please replace that valve while you still can. It will take 10 minutes now and give you peace of mind, vs 6 hours later / constant headaches trying to figure out if your problem is from that valve.
Top tip: a little dab of grease on the valve keepers will make them stick to the valve.
When I'm rushing through I often forget little stuff like that, it's a great tip!
When I was putting headers on my truck only 1 of the 12 manifold bolts came out without breaking. Said fuck it and decided to pull the heads and I got a good set of used heads
When it's that many broken? Totally understandable
i got them all out and i really wasnt that careful,thats on a 36 year old engine and that was in car
@@trillrifaxegrindor4411 Well sometimes you get lucky, on my old jeep I was gonna do exhaust manifold gaskets. Snapped the first bolt then said "You know what? It's not that bad of an exhaust leak" and walked away cause I don't have any extractors lol
"Rebuilt 454 heads $500 no lowballers,I know what I have"
There is so much more care in this than any craigslist post.
if i had insisted on reusing those valves i would probably have ground the step away from lapping them. and maybe even better rough ground the valves before hand and then lapped them to fit.
Love the channel, but, I wouldn't be able to sleep at night knowing that "that" valve was reused. This comes from a person very used to "falling down the rabbit hole" using used parts.
I'm pretty sure my professor would get a heart attack seeing that valve reused...
Absolutely nothing wrong with that valve lol it's a engine rebuild not a performance engine people wtf lol the lack of knowledge from you so-called mechanics is amazing to me
@@jonathanlawson4667 "Absolutely nothing wrong"
Dude. That valve pitting would put craters on Mars to shame...
@@edim108 valve was a little pitted up at the top when he was done and I guarantee you that valve would seal just as good as the rest of them lol it's a rebuild not a performance build
@@jonathanlawson4667 "a little pitted" is an understatement and a half.
And he said himself that this 454 is getting a blower...
If the plan was to just rebuild it on a budget and leave it NA, probably nothing bad would ever happen after reusing that valve.
But when you add forced induction to the mix, you run the risk of that valve not being able to hold up to extra stress.
I like the build, I really do. I understand the idea of doing it on a micro budget. What I don't get is being hard headed and not spending the $30ish for a new valve. An entire SET of 8 Gen IV intakes are only $70 from Summit. I like budget builds but I HATE even the idea of having to yank a head because I was so cheap I wouldn't spend money where it's smart.
I once decided to reuse a set of valve springs of unknown age in a motor I wasn't exactly being cheap with. A .030 over 302 Ford sporting KB Hyper pistons, SBC 1.94/1.60 valve. Comp cams billet roller rockers... you get the idea.
I ended up bending an intake valve for one weak spring.... 350 miles from home. Bus fare + time and fuel to return with a trailer + new valve and guide + gaskets + having to listen to my best friend for a week say "I told you so." + a new set of springs I should have purchased anyway.
You can lead a horse to water but you can't make it drink.
You realize he’s making a couple thousand dollars in ad revenue for each of these videos, right?
@@ChuckThree that's our point he has more than enough cash to do a better rebuild of this engine. A ounce of prevention is better than a pound of cure.
@@rgbigdog Ounces add up. Plus the whole reason he’s doing the build is to test wether or not you need to abide by the “proper” process for rebuilding a mild engine. Worst case scenario he’s out $200, because CZcams has already paid for his labor time.
@@ChuckThree i think the worst case scenario is that valve breaks off or the whole valve drops in to the cylinder, punches a hole through the piston, bending a rod along the way. then damaging everything that has a bearing. possibly pushing that rod out the side of the block. THAT is why everyone is suggesting caution. not that he might have to later replace a valve. the step in the valve is going to prevent it from seating correctly holding it open.
I don't understand why you want to save that one valve. It's toast. It's still toast after all that work.
A new valve, which could be purchased individually is under 40 bucks. But you got some real savings putting that turd back in. 22 bucks from Summit Racing as I priced it, but that old valve is just dandy.
P.S, nice touch pitchshifting the sound of the taps at 17:02, that's very SteveMRE1989 of you :D
The quality of the slow motion is amazing.
👍👍👍👍👌
Everyone’s really tripping over that cylinder... I’m sure he knows man... can we just appreciate this mans skills and the content he’s pushing out.
The cleaned cyl heads look great!
I have to confess I was not expecting them to be that good.
I would definitely consider getting a new valve and gasket matching and smoothing out the ports.
Great to see some more videos. I always look forward to your carefully narrated procedures. Very relaxing and educational. Keep up the good work!
I would be nervous about that one valve good luck great video
17:00 very subtle, I like it.
I'll be doing the valves on my '71 Maverick, 200 inline six. This is by far the most detailed video I've seen on the cleaning process! Lots of work to do, but I know it will greatly improve the performance of the engine--thank you!
Woah. Wasn't expecting part two so quickly!
Very nicely done and good to see people using and refurbishing exactly what they got props to you
Nothing like waking up to this! Great content and work man.
The crazy thing about projects like these is I bet he spends as much time filming and editing as he does working on the actual engine!
I'd bet it's more like 10:1 in favor of time spend editing.
👍👍👍👍👌✋✋
If there's any play in that overlapped valve's guide it's going to get hung up on that ledge. I'd definitely replace that one.
I had to wait sooo long on the machine shop that this time i just bought all new valves-lightly lapped them-good to go😁👍 took 2 hrs😃
The thread cleaner on the impact was particularly neat.
love this series, keep up the good work!
Laps new geometry into a valve and mentions possibly port matching like a boss... 🤣
So I started watching this video and am loving every bit of it. I turn on CC to make sure I get all the details, but end up never paying any attention to them. You all need to turn on CC for this video and read them. THEY ARE HILARIOUS.
Just like I did in the 60's, I had little money to work with, but learned a lot, lapping the valves makes a big difference, GREAT Job, GREAT VIDEO thanks
👍👍👍👍👍 indonesia

I can't wait to see this engine grenade itself
keep up the good work
Fantastic work man, really! I can’t wait to see this thing run!
thanks for the hard work recording these videos on top of the work youre already doing on these cars.
Loving this series so far! Can’t wait for the next upload!
Do a leak check on your valves with gasoline or alcohol to verify sealing fill chamber get brite light and look into ports for fluid.
Your doing a good job, I've seen shops do worse and even get payed.
Ahhh yes this is the video i was waiting for in this series. I really didnt think those valves would get smooth enough.
Great video, just what I needed to see, specially the pressure washing and cleaning. THANK YOU.
I've been hear when you first bought the vehicle and watched till now and honestly I've enjoyed every second
You actually released this fast enough that I hadn't caught up with the other one in my watch-later list.
Love to see the pace picking up. Here's some supportive words to help keep up your motivation :)
👍👍👍👍👍👌
Very cool! What amazing production values! Well done, with great humor. 👍🔧
Awesome work. I’m so pleased to be supporting you. Cheers🤙🤙🤙
I love those series keep them coming
I appreciate the confidence. Really like the content. Best of luck with this build.
I’ve done this whole job before. It definitely needed to be done. Wish I would have had this video. But I put my heads in a blast cabinet. Then lapped the valves. They were practically brand new when I was done.
Loving this biuld!!!! Makes me think I could actually do this.
Well done 👍👍I'm in the process of rebuilding a 3.4 tacoma engine myself. Yes, it takes a lot of time and effort, but it is also very rewarding doing it myself. Cheers 👍
Holy crap part 2 was fast!!! AWESOME!!!
Leftover cylinders heads... Just like Mom used to make. Yum!
At the end of the day it’s all about working with what you have. Yes I would have replaced the valve as that had gone way beyond what I’d work with on someone else’s car. But as a project - a task that you want to carry out ‘in house’ without any machine shop input - you do what you can with what you have. I have done this many times to keep things simple and ‘in house’ - and if you are sensible on what you think is achievable you can do great things and be proud of it - and it will work!
idk why i watch these i know nothing about cars but its so nice to watch
Great Job Mr. Finger. you are doing all that can be done to have a successful result. I believe this engine will run quite well for quite a while. Since it will be Supercharged the low compression ratio of the original engine should suit the extra air nicely. I am quite looking forward to see that all of your efforts pay dividends.
I’ve been using a 15L ultrasonic cleaner this week to clean a much smaller engine head. I’d definitely recommend it as it dissolves carbon and surface rust on all the surfaces including channels you can’t normally get Into
Your videos are always satisfying to watch
I like your hose idea on the valves. I was doing research and found that most pros dont recommend doing this with a drill from that end because you can cause wear on the valve guides and to only do this by hand. I do this with a drill on the valve side by taking a matching socket adapter to fit the suction cup and thats how i do it with a drill from the front. Never thought of the tube tho. Good stuff
Okay, now I can get up and start doing stuff. This 18 minute video was mandatory first!
you can also set the valve locks by swatting each valve a few times with a rubber mallet.
Might as well use the old rings and bearings.
Yup, I realize this is a budget build but I woulda replaced the valves and seats. Looking forward to the conclusion.
@@mwilliamshs they are press-in. You drive them out.
@@mwilliamshs ok. I learn something new every day.
@@vancepursley4316 the replaced seats are also hardened and fine with Unleaded fuel.
Always a good time, great work man.
Excellent video on cleaning the heads. I like your idea of the rubber hose and drill. Some videos clamp the drill right onto the valve stem but I never liked that. Thanks for the video.
Very enjoyable video! Thankyou for sharing!
I’ve been watching this series since you literally GOT this car back a few years ago this has been so long 😂
I suspect you’ll have issues with compression once fully assembled. Having a valve sitting “deeper” into the seat, will not fit within tolerance between the camshaft and keep the valve open.
It's called valve lash
Excellent job on cleaning the head's!
For the budget build mechanic, nothing beats this. You are a master of balancing thrift with reliability
I really love your channel. Can’t wait to see the next video.
So much progress... so many videos to watch for the 78... makes me worried there's not much being done with the 91! Excited for the next video on the 91 lol
Really liking this series
I have a bad feeling about that valve. I'm no expert on engine internals but I sure hope that valve doesn't come back to haunt you when you supercharge it
he is going to supercharge this engine? OMG
When I reconditioned a junkyard Vtec head for my Accord I lapped the valves pretty much just like this. I used old faithful (ancient Milwaukee corded drill), a small length of old windshield washer hose, and a bit of broken screwdriver shaft to get things done. Worked perfectly I used the lapping compound a bit differently using techniques that I learned from my teacher years ago.
Great job my friend! Congrats! 😄👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
Thanks for great video. It helps a lot. Especially spining with hose
👍👍👍👍👍.from indonesia
That intake valve, really needed to be replaced. It should be ok but it isn’t going to seal as good as it could, especially since you plan on supercharging it.
If it turns out to be a problem he'll put more money into doing it right. If he's proven anything over the past years of doing this it's that he is not against pulling out an engine and fixing it
Excellent. Love ur work
Great stuff 👏
2 episodes in a week!!! Wooo!!!
The xylophone noises were a nice touch
Im impressed that you can actually make engine building as boring as a documentary on wood chips.
Good job love this series
Those seats and valve heads cleaned up pretty well. My only trepidation really is the difference in installed height of the valve tips especially in regards to that one you really had to grind down. I would have expected it to have been overcome by shimming the rest of the springs to match the height of the tallest valve but then you get into differing seat pressures, etc. You could also overcome it with different length pushrods but that would seem to be far more difficult, logistically. Do you expect that the resulting change in effective lift won't have significant effect on the engine over all? As this stuff was recorded over a year ago I would be interested to know, if you're that far ahead, what the impact was. if any. Because science! :) Very much enjoying the series.
This is fantastic. Im doing the same on some old Ford windsor engines but a shop crane rebuild is in progress lol
Nice cleaning method!
Can’t wait for the next episode
Seriously..... Having reconditioned thousands of Cylinder heads I am in cringe mode.
Me too. I always hate it when people are too lazy or stupid to do things right. The 'bad' valve shows the radial grooves in valve face caused by not oscillating valve during grinding (10 min 20 sec)
Nice way to recycle heads. I hope that one over lapped valve and seat are going to work fine.
This is my favorite kind of video
Nice editing and filming angles :)
Thank you for uploading q new videos 2 days after the previous video.
Yum. Pickled engine parts. My favorite snack. XD
I am all for cheap this is a great video I have a damaged engine in a vehicle in a bad area some of these tips are very helpful! The cylinder 3 intake valve..... looks better but the $13 might have been a better option she is getting really thin.
I JUST WANT TO SEE THIS PROJECT FINISHED AND ON THE ROAD!!!!!
His is awesome two episodes in 2 days
