My crankcase Breather Hose cracked since it was very hard and brittle. I was not able to order the OEM, but found this Dorman PCV Hose Part # 46012 locally.

Thx for the tutorial!! My mechanic wanted $1600 while I did it myself for $300. This was also my first ever repair on a car so I recommend anyone out there to go watch this video thru a couple times and learn the repair themselves. You’ll save a lot of $$$ and learn a couple things.

Don't forget to give the video a thumbs up if you found it useful thanks for watching!

Thank you sir. Really well explained and I like how you actually time lapsed as opposed to skipping over like the other videos 👌🏼

Just wanted to say from one 03 g35 owner to the next Thank You 🙏 I like how you take your time to say and show exactly what uour doing im getting ready to replace my valve covers.

Thank you for the video It was very helpful. The local shop I took the car to gave me a quote of $4200 to change my valve covers with coils and sparks plug. Just finished changing it myself and spent roughly $300 for the full project + my time. Highly recommend doing this yourself if you have the time.

This the best video for this I seen yet. I’m doing these and throwing on my gtr injectors , ported lower plenum , spacer and 4inch intake then flashing the tune at the same time as this

Another great video Eric. I always enjoy them. Stay safe out there and we need more p11 videos.

Love you man please don’t stop doing stuff like this on god you help a lot of people with these vids man and you help us save a lot of money thanks man fr fr I mean it

Great job in explaining and displaying. A layman can follow your lead. Excellent job.

Just installed a magnaflow on my 350z, spotted an oil leak from the valve covers and recesses of plug wells. Unfortunately I have to replace the covers too but you're helping me save on the labor! Thanks!

thank you! i havent touched a engine in my life and i learned so much and was able to take care of what i needed on my 2004 g35:) made me realize i love to work on cars

Great idea with the fishing line! I think it will be even better if the knots are on the outside of the cover so the lines are easier to pull out while keeping the gasket seated.

Thanks for making this video cause I just found out 3 days ago I need this done to my ride.

Had oil in cylinder and thought it was just the gasket ended up having a crack your video was the most helpful hands down 🗽

Best video for this job by far on the internet. Very explanatory, detail where it matters, and no time wasted on small talk I don't care about. Great video my friend keep up the good work!

This video was done incredibly well, thank you!

Just did mine, thank you for this video. It really helped. Also it’s easier to remove the plenum first then unplug everything.

Was going to do this on a 2003 G35, had all the parts sitting ant home, just waiting on a non rainy cold day. Got rear ended at a traffic light, and the insurance company wrote off the vehicle. Was really looking forward to all the frustration taking apart all of those bolts and wires too. Great job and thanks for sharing.

I used Victor Reinz 15-10107-01 gasket on 05 G35 and they stayed in the valve cover without falling out. No tape or string required. Also install new NGK LFR5AHX Ruthenium plugs. Did a slight porting and polishing of both the upper and lower plenum. My Butt Dyno says I have a noticeable increase in power.

Great tutorial once again. The electric driver sure speeds things up. A quick tip I used when I did the valve covers on my previous Nissan: I sprayed a tiny bit of spray glue on the valve cover so that the gasket wouldn't fall out when installing it.

Best G35/350z DIY KZfaqr

Perfectly explained every step...GREAT.

The tape idea 🤣🤣. Great stuff tho awesome vid Eric!

Bro you are the best at this on KZfaq literally rebuilt alottttt on my front end just from ur videos

Went To Turning My Socket Wrenches Today, Cause Your Video!!!...My Gasket was leaking so Bad My FX Was practically Pouring Out Oil.

Thx for showing the RTV gasket part brotha, have to do this same job soon still nervous about the make a gasket tho lol great detailed video 👍

I used permatex high tact to hold down the gasket. Works perfect. Excellent video my man ! Super easy to understand .

Very informative. Thank you bout to make my repair now. Hopefully I just have to replace gasket & not the whole valve cover. I initially thought you could replace the gromments, but I know now that it’s all one piece

I was just watching your spark plug tutorial and found oil all over one so thank you I might try this myself next weekend. At the very least I have a good understanding of what this is so I can take it to a mechanic if I need to. Thank you! Glad I decided to change the spark plugs myself, I would have been charged so much $$$ and would’ve had no idea what was going on.

Bro you did good. Ima start my gasket job next month in March 2023

my mechanic did the job for 500 and he paid 250 out his pocket for the gaskets he really only did the job for 250 so i call it a win win hes the goat

Yo bro thank you I love how you explain everything definitely helped me out

Me encantó tu vídeo, definitivamente esta es la guia que usaré ya que contiene información muy importante que otros videos no comparten👏. Gracias!

Good job not editing out the tape mishap like most people would have. I just used a few dots of RBD around the gasket to hold it in place but the fishing line was a good idea too. How about removing and installing that #7 bolt on the drive side valve cover!? They knew what they were doing by putting those back there...

Gonna tackle mine after this video. Great work man. Very helpful. 👍

Love this video just helped me change out my valve cover gasket earlier!!

Great video my guy. Im going to do this myself on my 08 FX35. Appreciate all the info you packed into this video. Sub earned!

Thanks bro for the vid. You saved my ass. You have a subscriber for life now

Use weatherstripping glue. A dot of it, around each bolt hole will be enough. Dries very quickly. Once you set it down it won't move. It's right next to the silicone at the auto parts store. I use it on o-rings and gaskets that won't stay on by themselves.

Doing valvecover gaskets on the 05 g35 tonight thanks for the video bro

Have to do my car soon so I looked up the video, thinking it was gonna be a pain. Doesn't look too bad. Thanks for the video. 👍

Exelente video, gracias por compartir sus conocimientos

Thanks for the grate informative video you walked me threw it when I did mine lol

I tried the fishing line works good just tie it on top of velve caver

It's such a great video. I really appreciate it 🙏 this saved me nearly 2,000 dollars ... these mechanics are all trying to get rich from one customer these days 😅

Thanks for the video brother. I didn't have tape or fishing line and it took me about 5 attempts on each side lol

Thank you for making this video

Super sick man, gives me the confidence to do it myself.

Thanks for the the vid. I'm in OZ and some models are called 2003 v35 skyline 350gt. Where can I get a service/repair manual for mine with step by step repair instructions? Please.

Used your fishing line trick ! Thank you that helped a lot lol

Great Video man!

Good video. Very helpful. The edits and the part Pics was good 2.

Very cool video, well done! Two remarks though: 1) you are a brave man installing all those cover bolts with the intakes left open, ALWAYS stick some cloth in all of them while you work or one day you'll drop a bolt or a washer in there, and you'll be *****ed ;) 2) It would have been worth checking the valve clearances once you had the covers off, might as well do it now. But overall great video, will go back to it when I do my covers.

Great video buddy. 👍. As good as Christ Fix’s one. Once again congratulations 👍👍👍

Good shit, well explained and good fishing line technique.

I would think use a little bit of gasket maker to hold gasket in place would probably work as well.

I need to do this job next weekend. Thank you for the video, I feel confident now to do the job. Question...did the felpro set come with all intake gaskets etc.? Maybe you mentioned it but I missed it.

When you took the harness off the right side. I can't figure out where the 2nd to Last plug went in...

Any way to put a freeze plug in behind the timing chain at the top. No space. Thanks.

Perfect, thanks Eric

Great work in the video bro. Very useful for sure.

nice technique with the fishing line

I need to do this soon, for $25 more I can get new valve covers as well on eBay. Thinking about getting new coil packs they have a package for $98. New valve covers, gaskets, and coil packs. I'm thinking about painting the new valve covers with some high temperature paint. Need a color that will pop, might as well paint the plenum too. Then finish it off and paint the cam covers. Just bought a 04 G35x and it's in great condition. It does have a small leak that I've pin pointed to being the oil cooler gasket. Then I noticed there's oil buildup on the driver side valve cover. It's likely just all of the spilt oil from missing the fill hole while filling it with oil. The other side isn't bad, just dirt and 16yrs of build up. I'm going to change the plugs, so I was thinking might as well replace the valve covers. I'm curious how clean the intake is, as well as the cams and valve train. Anyone know if you can clean them while the valve covers are off? Would all of the crud wash down into the pan? Just flush it out with a light weight oil. Maybe I should just wipe it down? I just figured since I have everything accessable, might as well give it a good cleaning. I don't see why it'd harm anything, unless it's really dirty and there's sludge everywhere. I don't think mine is, the engine is runs smooth and is pretty quiet. If I get some seafoam in a spray bottle and just give everything a good soak. Then go over it with an old toothbrush. Any thick sludge, if it even has any I can wipe away with a microfiber cloth. Just making sure nothing thick falls into the oil pan. Not sure if it'll even be worth the trouble. I'm not expecting any miraculous changes, just maybe better response time and gas mileage? I'm very mechanically inclined this is an easy job. I've just never cleaned the valve train before, so I'm curious if it's even worth the hassle? I will also clean the intake really good as well as the throttle body. If I unplug the throttle body and clean it, will I still have to do the re learning procedure? I'm also going to add some more intake piping so I can relocate the MAF and intake filter. Right now it's resting by the dip stick right next to the valve covers. Wanting to bring it right behind the headlights into the bumper area.

omg, that tape/fishing line is a great idea. but i never thought about the problem. I just put gasket maker on both sides of the rubber lining without thinking. i replaced my valve cover four years ago and so far no oil leaks yet.

Why was gasket spray adhesive not used? Just curious....

Very well done. Great video. My mechanic friend advised that I replace the valve covers. He said the plastic valve have likely warped from heat and age. Any thoughts on this? Thanks for the detailed video.

What size for the upper intake manifold?

best video and very clear

It's not the stickyness of the tape or the texture of the fishing line, it's the surface area and friction coefficient. The fishing line has a lower frictional coefficient due to it's surface area than the masking tape.

Awesome videos bro just what I was looking for! I would recommend you change the valve cover as a whole instead of the gasket due to the fact when your spark plug o rings give out you will have to do the job all over again🤦‍♂️ just a heads up 👌

How do you disconnect the connector for the drivers side intake cam position sensor? I can't feel a locking lever In the video, you just reached back there and boop, it was disconnected. NVM, I looked more and figured it out. The green tab needs to be PUSHED towards the sensor connection.

i gave you a thumbs up bro next time a help tip you forgot is the tool sizes .other than that thank you ill be working on my 2006 350z

how to differentiate VQ35DE exhaust valve lifters from intake valve lifters

i bought a g35s 07 yesterday, they say it has a valve cover gasket going bad, it seems white smoke coming out from the engine and smell like burn oil, i just have 17 and have not too much funds to get fix rn, can someone tell me if i can have it like that at least for a couple of weeks?

Could you tell me where you took the pictures of the engine?

is servicing the injectors required ? or can i just finish doing the valve cover gaskets once all that’s off ?

By any chance do you know the torque values for this job from the valve covers all the way up the final build up? Or were i can find them. Iv been searching online but I cant seem to find definate answers

Great video just did the job myself with some aluminum ones, I was a little confused when I didnt see you pull out the last coil packs lol threw me off a bit but other than that 👍🏼👍🏼

Thank you 🙏🏼 🙏🏼

Great video - Thank you! I'm gonna see if some spray on permatex tacky sealer will hold the felpro rubber gaskets in place while I do the cover install

What were all the tools you used?

Very good work

8:15 what is the name of the hose I cracked mine but don’t want to order the wrong part

wow !!! awesome video.....really intense....didn't realize all the gaskets that are involved in the valve cover gasket replacement. what an ordeal!! The fishing line idea was brilliant! do you suggest an 8lb test or an equivalent ?? lol. I may have been suggested to have this done on my G35 2006 but after looking at the video.... I need a loan $$$.. I already committed to the cooling fan replacement. $$$ So it looks like.....well you get the picture. ty for your time

Fishing line 👍 I 💘 it

Timing chain & guides next??

Great Video, Great job

Use a small thin layer of silicone to hold the gasket in place.

Do you know what the small hose is that connects under the throttle body? Mine broke the other day and it is leaking coolant everywhere. I can't find anything online about it.

Can someone help me? I snapped one of the cables in the back.

Dead when i seen tape didnt work and you cut😂

I did a tune up on an 06 G35 with 150k. Plugs, coils, cam covers took me all of 6 hrs. The passenger cover was terrible to get in.

Great video! Really helped a lot. I just got done doing this. It came up with three new codes. Two of the codes where because of the valve covers. I was mention that i could have possibly over thighed the valve covers. Even tho i used a torque wrench. Is that even possible for it to throw a code for that because of over thighed?

excellent video thank you my friend! So i only need the valve cover gaskets and the spark cover gaskets right? I was told by infiniti dealer my 2003 g35 sedan six speed manual has the valve covers you have to replace because the gaskets are a part of them?

Question: would wax help to keep the gasket on until installed? I was thinking the wax while room temp could keep the gasket in place until completely installed. Once the engine heats up. The wax would melt away and leave the gasket completely in tact. Well thats my theory anyways 😮

Great video bro!.. Question, I'm having trouble getting the bolt off of the passenger side valve cover in the back,any suggestions on what tool to use because it's not much space at all back there, thanks

I'm trying to look for a video like this but for a head gasket replacement.

I need you to do this to my ride ! Lol

This is how a how to video should be done! Absolutely fantastic! Liked and followed
