This has been by far the best explanation of a "HowTo" process for this engine.Infiniti G35 DE!! Im going through this exact job on my own vehicle, and have had reservations about how to set the timing properly. Not anymore!!!!!! My mind is now set at ease. Keep posting videos and" how to" Your a good teacher!!! Thank you
I appreciate the kind words!
Wrong! He never even mentions all the O rings that go with this system and they must be replaced behind the second cover assembly. This video is literally only a fraction of the complete job each of these engines will require. Guaranteed facts!
Without these O rings you will still have lower oil pressure internally. I've built many of these engines. Every single time the rest of these steps was missed, the engines suffer catastrophic failures. Every single time!!
@@natepressley3379can you be more specific? What are the o rings called? What should I look up to figure out what you are referring to?
They are called O rings @@Rex-cm1wx
Extremely thorough videos for techs & home mechanics, thank you, no one else on CZcams took the time to remove cam pulleys and show the markings.
Glad it helped
Very very good explanation. I do a ton of these at my shop per referrals from one VQ enthusiast to another in the DFW area.
Couple of tips I’d add for some of the less experienced DIY’ers: a pair of chain vice grips can be used to hold the cam gears (phasers/actuators) instead of pulling the VCs to get a wrench on the cams to keep them still.
Spray PB blaster or WD-40 on the dowels before removing the timing cover. They’re usually full of crap/oil/rust and the penetrant will break they junk up and make getting the cover off much easier. Also I like to give them a few light taps with a punch/hammer to break the junk up a little bit.
Run a few of your front facing timing cover bolts in before you start the bottom cover bolts that go in from the oil pan entrance. You want that pan nice and flush before you start those bolts or the bolt holes won’t be properly lined up and you’ll cross thread them. You don’t want to cross thread those bolts!
10/10 on the video. Couldn’t have explained it any better myself and like I said, probably done this job 25 times in the last 12 months 😪
Sincerely appreciate it brother! I’ve done like two dozen of these jobs ever, which I consider to be “a lot” haha, but I’m a big VQ guy (obviously if you’ve seen the channel) and so many people struggle with these for some reason.
That’s fantastic advice for the DIY-er as well!
If you tell me what shop your at I’ll drop DFW mentions for you in all the VQ groups on SM.
Im in Fort Worth tx where are u located I need a timing chain replacement on my 04 g35
Question is the water pump an timing same for G37s an G37 ?
Glad to see more in-depth videos on HR’s/VHR’s. I also made a video going over this as well but kept it a bit more brief. Kudo’s for showing another perspective on the job
I have a 2013 Nissan Xterra with a VQ40DE. Same family of Nissan motors. All this applies to that motor also. Currently, there are dozens and dozens of CZcams videos that explain the specific procedures for finding TDC and aligning everything. DO NOT depend on just this one video. They all have great info from a different perspective. I had to watch most of them because I upgraded my timing chain guides to the ones found in the 2019 Nissan Skyline VQ37HR twin-turbo models with a bit of mmodifications. Jim Wold Technology in Escondido, CA gave me that tip. They are the Nissan VQ wizards. They recently built a few VQ race motors for a Baja 1000 customer in Mexico.
that was super good. very easy to follow and understand. thanks for that one its probably one of the more important ones i have watched. thanks for that one.
Glad you liked it!
Gotta say this was really well explained
Gotta say.. thanks!
No he left out important steps in the removal process..
I need to do this job this winter but dreading it lol
Same here, Im debating on only replacing the main chain and not the cam chains.
Dude I am so grateful I found this video
I had both cam banks jump when I released the tension on the primary chain
Can I rotate cam banks clockwise or counter-clockwise without fear of valve/piston contact until I am lined up appropriately?
No this video will lead you to hell, take it to a certified mechanic
Thank you for doing this. My G37 rattles at idle or low rpm light to no load. It has 100,000 miles on it now. I might have to dig into it.
Great video dude! Thank you for explaining and I subbed up for more! Although I have a question. I'm going to try my best to make this as simple as possible. I need to remove the passenger intake gear out the way to get to a messed up gallery gasket screw head (I rushed to fast, I've done a few of these jobs this the first screw I fucked up actually.) So i wanna just scoot or remove the cam gear. Now the only problem is I made all my white marks on the main chain and all 5 gears just in case. I never set anything to TDC because I wanted to keep my hands away from touching or spinning anything, well that went down the drain. I popped the valve covers off, I wanna hold the intake cam so I can remove the gear. Would you advise entirely against this? Should I hold the cam with a very good gripping channel lock? Or would you use a wrench for that large nut like peice on the front side of the cam? Or should I put everything back and spin it all to TDC and then proceed?
TDC and you’ll have to hold the camshaft itself. No good way to cheat that. Plus it’s easier using the factory colored links than painting them 👍🏻
Greatly appreciate this video . Months ago I did same job . All Z1 parts full timing chain kit .
Wasn’t well guided when I went to crank car for got to pull full pump relay and spun a bearing .
Not sure where’d I messed up but if I had this video before , doubt it would’ve happened
Glad it helped
Why u spun a bearing u didn’t put it on time?
I'm going to be rebuilding my first VQ and was wondering for the cam chains is there a tac for the tensioners that I have to pull before doing the main timing chain?
Brass putty knifes are your friend for this job. 6 minimum to avoid any damage from prying.
do you absolutely have to count the links after you rotate/spin the engine?? i made sure i was on timing(100% sure). and put timing right back on tdc after i spun it around several times.
No you do not. I never do. But many people have low confidence when they set the timing so it’s another way to double check that they didn’t miss it by a tooth.
Assuming the secondary chains and cams were not removed, but the primary chain was, can you independently rotate cam bank 1, cam bank 2 and the crankshaft in various positions (clockwise or counterclockwise) before finally rotating them back to the marks before ultimately reinstalling the primary chain on the sprockets?
I ask because I don't recall whether I rotated both banks clockwise or counterclockwise before rubbing off my paint marks and ultimately starting from scratch. I'm assuming if the intake cam marks are on the timing cover indents, my exhaust cams are in time as well since they rotate together. But, can I be 180 degrees off my crank mark?
Yes you can. You shouldn’t be doing 180s with it.. the cams are a 1:1 ratio obviously so you just have to watch out for piston to valve contact.
Great job very useful !
For anyone stressing about timing this video is for you ..
I appreciate that!
Man my 08 g35 sedan has 92xxx miles in here worried about those gaskets almost every day
Check your oil pressure. If the pressure is too low, might be the gasket leaking. Also look for codes for cam gear position.
Dang man, very nice work on this his one. Thank you
Good video best one I seen great job
I appreciate it!
Thanks so much for the video. I really appreciate it. Im wondering why the water pump when failed leaks from the upper oil pan gasket? Thanks so much
Pete are there any cam holding tools to hold cams in place I’ve got the 3.6 pentastar ford cam lock tools gm cam tools I can’t find any cam lock tools for Nissan
Yes 17mm & 19mm wrenches with vice grips 😂
@@Pete_Tech_ adjustable wrench’s not vice grips, what are you a junior mechanic?
Hey bro can you please make a video on how to replace the VVEL control shaft sensors or moduel/ mortar please
Very good video my man
Thorough walk through. Thank you
Glad it was helpful!
So I pulled the timing cover to do gallery gaskets, chains, water pump, Guides and tensioner
I got the marks all lined up one the main chain and everything is perfect but one is off one tooth on the passenger intake gear
I put the new chain back Some way just because it ran fine
Is it possible when I was turning then engine over backwards with socket on the crank it jumped a tooth?
Typically spinning backwards won’t cause it to jump time assuming the tensioner is healthy and the chain isn’t stretched. Now if it was definitely off by a tooth, it’s possible your chain was severely stretched. The new OEM chains have timing mark colored links, they need to be set appropriately. That’s in the video 👍🏻
@@Pete_Tech_thank you so much for the reply! One last question
I set everything on time to the marks with a new oem chain
The only thing im curious about is can I replace the oil pump with out dropping the upper oil pan
So I bought the Concep Z gallery gaskets, They say there also updated and "better" than oem. Should I trust them or return them?? Now Im worried.
They are. Same company that designs them for Z1. Nissan themselves doesn’t even use the original material that came on the previous galley gaskets pre-2014.
seem like a ex BMW employee is working at Nissan. making a simple design to a over engineer nightmare. these engines isn't user friendly.
I’m kind of confused on the part at the end when you count shouldn’t it still have 26 links no matter what ? Like why turn it over 2 times
Some people are convinced they have to turn the engine over multiple times to check the timing. Turning it over one will not put the cams in TDC, as they spin 1/2 revolution for every crankshaft revolution. So you can put in back in tdc to check marks OR count teeth. Personally, I never do.
@@Pete_Tech_
Personally you never do,,,, You just have to be special and confuse people even more
@@velizarmilutinovic2947 cause he misleading people, I’ve been trying to tell people he doesn’t know what he’s talking about, it’s people like this who make you feel like he knows but then I’m telling you there more than 3 timing marks you have to verify and make sure of before removing anything
@@velizarmilutinovic2947 you see how he didn’t directly answer your question? SMH 🤦
@@johnmarco5017 so do the colored links on the chain matter(after turning engine/setting back in timing)? because i dont see how it would all of a sudden have more or less links in between, when we are just turning engine, not adding or removing chain links?
How bad would it be if I just replace the main chain and not the secondary chains?? I don't really feel comfortable taking those secondary off and replaicng the tensioners for the secondary? They look pretty fresh
I do that all the time. Primary chain and components are fine if the secondary’s are healthy 👌🏻
Does it matter if its just a tiny bit off one of the color marks
Yes, that’s out of time! Not good
What color are the galley gaskets? I found a piece of what looked like brown gasket material in my oil when I changed it today. I was wondering if maybe that's what it was.
That is definitely part of the oil gallery gasket
Yes. I’d bet on the bottom left corner of the lower gallery.
Im going to have to be going through this too soon so this video will def be a go to, got a solitary p0011 code and sensors are all good. 2013 370z Nismo with 60k.. From experience what could the most common cause to this code?
I plan on replacing it all anyways... Going about 15 degrees out of timing😬
My first guess would be a stretched chain or gallery gasket problem. That’s definitely a considerable amount. Maybe pull the VVT Soleniods and check for debris or metal on them. But I’d recommend going in and doing a refresh.
Thank you, will do, solenoids were fine, so refresh it is...
What is the timing chain tensioner torque specs I can't find them anywhere....
I just opened up my timing cover after I got a p0021 code. It looks like my intake cam phaser is a couple degrees off. Does that mean the chain jumped a tooth? And what does that mean I need to replace? I already ordered a new phaser but should I also order a new primary chain and tensioner?
Me too 🤣
can a bad camshaft phasers be the reason a car wont start?
A completely failed phaser can prevent it from starting and/or can make it run extremely rough. Intake phasers occasionally fail on the VHRs causing a no start but will usually set a timing code as well.
You connot get that bolt on the 06 without pulling the gears
How do you remove the rad cap housing in order to remove cover , Is it threaded ??
It is not threaded. The radiator cap housing is secured by 10mm bolts and it’s held together onto the valley pipe via O-ring seals. It comes apart with a little bit of a fight usually. Make sure to inspect and/or replace the o-rings on the valley pipe. Install with a synthetic lube.
@@Pete_Tech_ thank you
I’m doing a chain replacement on a 2004 Nissan maximum 3.5 first time just trying to understand your video
Advice is don’t do it and take it to a shop because ioa fwd vehicle
It’s the same process but the covers are different and space configuration sucks. Definitely not for the average DIYer, and I don’t say that to discourage you.
Great video. Thank you!! Wherr are you located? Id really rather pay someone to do my gallery gaskets. 🙄
Minnesota 😅
Hi I just subscribed. I like your video very informative. I have VQ DE and i want to rebuild by myself. Have a question. Do i need to change my gallery gasket? Or can i reuse it? I have 238,000 mileage on my g35 and i started hearing the marble rolling infront of my engine.
Replace!! 👍🏻
Replace everything and do it twice: the second you try to reuse parts you will get bit lol
Yes thank you so much 🙏🏽
Complete with regard to every detail explanation. THANKS !
You are welcome!
If my key is lined up at timing mark on bottom crank am i at tdc or is it possible to be off 180degrees i have 06 altima ser im trying to do it without removing intake
The only way to reference TDC is verifying all timing marks (crank and cams). The camshafts can be 180 out when the crankshaft sprocket only is at its timing mark.
@@Pete_Tech_yeah he knows what 180 out means bud… smh nobody has a degree gauge smh
Does anyone know a reputable shop in western NY for VQs?
Great video
Hi!
Nice vid, please can u do VVEL 😊
Vvel in what regard? Lol
How to mount and adjust vvel
I’m changing my cam phaser , due to the encoder issue. So does the 2nd chain have to be in time for it to start properly. Or just the main chain.
BOTH! The chain has marks, and so do the gears. Shouldnt be hard to set in time 👍🏻
@@Pete_Tech_ so I’m assuming I’ll have to take the other cam phaser off to set the chains on bank 2 as well. Or just turn the crankshaft ?
Hey man I just got it open. What Size nut is that you have on your harmonic balancer on the crank so you can time the engine. I don’t want to get mine jammed and stuck
Bro you saved me tons of money. I Changed the phaser on G37. Took me about 2 week with parts and stuff. Labor was a bitch doing it. Brother you saved me well over 2k. Thank you so much. I’m going boost soon btw. So excited 🔥
@@1MrVQ do Not turn the cams separately from the crankshaft!!!
Are the 37s an 37 the same timing Chan an water pump the same ?
Identical 👍🏻
has anyone actually done this, does this actually work ?
Just passed 207k on my g37x sedan I really need to do this for the gaskets that go bad on these but the thought of me opening my engine like that is 😬🤣
Definitely not an easy project, but it’s doable!
Don't wait for it to go into limp mode bro just do it haha (it's a pretty difficult job but the car is essentially useless when it finally breaks so really you have nothing to lose and everything to gain)
@@Pete_Tech_👍🏽
@@quinceymorris7942yeah I think I’m gonna either have it done or do it myself
@@markus360sI thankfully found someone on the side who did my oil gallery gaskets for me for $700 but shops usually charge $2,000-3000 in labor alone. I'm at 161k and my oil gallery was already falling out so get yours done asap.
How do you recommend tourqing the bolt for the galley gasket that is under the cam gear?
Just hit it with a dab of red locktite and tighten as much as you can. It’ll be fine 👍🏻
WRONG! take off the cam gears!
My intake cams, skipped timing when I took off chain tensioner first, can I do this set up and it’ll go back to how it was?
No response one month later 😂
Did you fix it
Yes, I Litterally explain that in the video 🫠
@@Pete_Tech_ damn zaddy don’t get mad
@@velizarmilutinovic2947 and yea I did lol
@@velizarmilutinovic2947 I know😂by that time dude probably towed his car to the mechanic
Could you do a a video on how to swap the cams ? That would be awesome I like your detail work
He won’t, he specifically ignores the 4 timing marks on the intake and exhaust cams on purpose.
How do you do the oil pump change
The oil pump requires the removal of everything in the video, in addition to the upper oil pan. Then it is pretty easy to remove.
Its confusing how you make the top of the chain tight without having slack I do it and i keep rotating them and theres always slack i cant get it to be tight without it being off time
There has to be slack for the upper tensioner to go on. But that goes on last imo.
I keep doing it and it keeps landing on the 27th link
Idk why
Nvmm i hot it on point
Thanks a bunch brother
Anytime!! God bless 👌🏻
Good walk through video. But work on your audio editiing. I'm half deaf now.....
Noted!
😂😂
do the cam chains jump when i take the primary chain off?
Yes...this is what I am currently trying to fix
No.. bank to bank camshaft timing will move, yes, but the camshaft to camshaft chain cannot jump. In this video I specially address the fact that if the cam timing changes bank to bank, it can easily be reset.
Yes it does change, do not attempt this job on your own. Take it to a insured mechanic.
gracias
Willl this work for a vq35hr motor 2007 350z
Yes, same exact setup
Okay on your video when you time the 3.5 engine y do you spine the motor after you get everything done . Do you have to turn it
You do not have to turn it. I never do. But that’s also because I’m certain everything is on point.
Where u located
Zimmerman, MN
uhhhhhh excuse me but... those are links of color...
Very greathful
Video for VQ35DD doesn’t exist even dealership never heard of engine I have 😂
It will be the same timing system. Nissan doesn’t have any new tricks when it comes to timing. Even the V8 is nearly identical to this.
@@Pete_Tech_
Well it doesn’t have timing MARKS on the BACK COVER neither it has any marks do you could align with VVT circles ,,,so you pretty much have to GUESS like 10am and 2pm also to be safe gotta remove cylinder 1 spark plug to be sure it’s all the way up so yes it’s definitely confusing especially if doing it first time as I am right now today 2/21/24 lol
Another problem is NOWHERE TO FIND PARTS even dealer has to order and when I go to Nissan dealer they don’t know what’s Infiniti then I have to explain 2020 Infiniti QX60 is same as 2019 Pathfinder with VQ35DD engine ,,, but they still stare like deer into light
The VQDD has timing marks on the cam gears themselves. As well as colored links. Holler at me on Insta if you need help. @ Pete_Tech_
Without removing the entire cover assembly and replacing the o-rings on the back side of the cover and the front cam bearing covers you're literally wasting your damn time even doing this much work. Not hating on your abilities, yet def hating on the half ass incomplete education of what really needs to be done to ensure proper oiling of this engine design. Good luck...
In my experience, (which may actually be far less than yours), I have not only never seen a failure with those, I’ve never even heard of it being a failure point. There is far more you can do to this engine in terms of replacement/ reseal. If it doesn’t fail, seems that is more of a waste of time.
❤🎉n
Another misleading video that’s gonna cause y’all to take the car to the STEALERSHIP, he didnt show you how to properly make sure the engine is a tdc on the COMPRESSION STROKE! before removing anything. These people love to make short videos with the job half done skipping extremely crucial steps, also he’s doing this on a motors that you haven’t seen start after the job. Get a repair manual guys
😂, please explain your opinion on the difference between setting in TDC prior to removing the timing cover versus after removing the timing cover? I’d love to potentially learn something 👍🏻
Please explain,I am doing this process currently
Why do you say misleading. What did he miss out
I sent mine to top dead center after removing the cover, and everything worked fine. You’re just trying to start a controversy.
@@Pete_Tech_ Sure Pete, you didn’t verify the exhaust timing marks or intake timing marks with the respective colored links on both chains before removing, didn’t address the fact that the camshafts are spring loaded and will move when the secondary tensioners are relieved, also note guys there is no moving the crank or cams separately in timing, it’s an interference motor. The timing marks need to perfectly match before removal, then obviously before installation. You see just a little after 18:00 he shows you the colored links in the correct position with the mating marks matched? He didn’t do that before removing any of the timing parts in the beginning of the video. That’s were everyone watching this will mess the motor up. He should have did verified like he showed in 18:00 that the mating marks were correct BEFORE removing anything.
Pay attention at 16:20 he skips MAJOR steps and goes to pulling the secondary’s off, NONONONOOO you have to make sure ALL. The mating marks are line up before removing anything!! There’s more that the three he showed in the beginning!
You see at 16:50 the exhaust cam on bank one moved when he took the secondary off?? Y’all are gonna fak it up following the short hand videos. I told you.
This dudes a faking tool. Sorry guys😢
enjeyed lol
This is wrong
Thank you 👏
