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

[@Aydn999]

Extremely thorough videos for techs & home mechanics, thank you, no one else on KZbin took the time to remove cam pulleys and show the markings.

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

[@Pete_Tech_]

I appreciate the kind words!

[@natepressley3379]

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!

[@natepressley3379]

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!!

[@Rex-cm1wx]

@@natepressley3379can you be more specific? What are the o rings called? What should I look up to figure out what you are referring to?

[@afizzle7631]

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 😪

[@Pete_Tech_]

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!

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

[@omytorres4125]

Why u spun a bearing u didn’t put it on time?

[@JChic-dh1pz]

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😬

[@Pete_Tech_]

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.

[@JChic-dh1pz]

Thank you, will do, solenoids were fine, so refresh it is...

[@carlosleandry12]

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

[@Pete_Tech_]

I do that all the time. Primary chain and components are fine if the secondary’s are healthy 👌🏻

[@NURsMec]

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.

[@Pete_Tech_]

Replace!! 👍🏻

[@Pete_Tech_]

Replace everything and do it twice: the second you try to reuse parts you will get bit lol

[@Newbgainer]

Brass putty knifes are your friend for this job. 6 minimum to avoid any damage from prying.

[@MRTuning704]

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?

[@Pete_Tech_]

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 👍🏻

[@MRTuning704]

@@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

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.

Check your oil pressure. If the pressure is too low, might be the gasket leaking. Also look for codes for cam gear position.

Does it matter if its just a tiny bit off one of the color marks

Yes, that’s out of time! Not good

[@1MrVQ]

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.

[@Pete_Tech_]

BOTH! The chain has marks, and so do the gears. Shouldnt be hard to set in time 👍🏻

[@1MrVQ]

@@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 ?

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.

[@b1maxc135]

How do you remove the rad cap housing in order to remove cover , Is it threaded ??

[@Pete_Tech_]

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.

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

[@Pete_Tech_]

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.

[@jeffspears8801]

Yes...this is what I am currently trying to fix

[@Pete_Tech_]

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.

[@johnmarco5017]

Yes it does change, do not attempt this job on your own. Take it to a insured mechanic.

[@xenos5783]

can a bad camshaft phasers be the reason a car wont start?

[@Pete_Tech_]

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.

[@bostanfill5190]

How do you do the oil pump change

[@Pete_Tech_]

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.

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.

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.
