G37s Gets Valve Cover Job, Throttle body’s, Upper Intakes, Rocker Cover Removal VHR & maintenance

- 2008 G37s coupe valve cover job. Random multiple misfires due to worn gaskets on the rocker cover causing oil to drip on the plugs resulting in my misfires. The car wasn’t driven when the CEL came on. I was home about to leave when the car started up but then misfires with no lights(cel). So I shut her down and put the scan tool on it. Started her back up she immediately misfires and CEL on bank 1 cylinder 1 showed on scan tool as misfire, then I received the random multiple misfires as I let the car run for a few seconds as I scanned. I’ve seen a little oil on the boot when I did a spark plug job about 60,000 miles ago. But it was minimal so I put it off until now when it failed completely. Lucky for me it happening at home. I post this video for those who may want to tackle this job yourself to save money. Comment Below👍🏼
I have to say I've been captivated this entire video. I plan on doing all the work on my g37 so ive been binging different videos and overall learning general car maintenance on yt. Great Content.
Fam. That good to hear. I appreciate that complement. Thanks for Watching
@@tgreen200 nice work.
Thanks for being detailed bro you got something good going your way god bless
With there were more creators like this that go into detail on our cars
*Wish
Where did you get the manual pages??? (Dumb question I know)
Very good video for newbies thanks!
Hell yeah i have a buddy who’s getting an oil leak into his spark plugs we need to change the valve cover gasket
Yes sir I would. I was lucky. I been knew it was leaking on to the plugs but I put it off. And then the day before I was going to do the Install she decided to fail all together while I was at home. Good thing too. Hope it goes well for you. Thanks for Watching Fam 🤟🏼
That's the situation I'm in now literally..Had a misfire so I replaced all coils. A year later changed the 02 sensor. Misfire reoccured on new coil again. Mechanic said oil was getting into the spark plugs causing damage on new coils. He told me I needed to change the valve cover gasket. My issue was how come he couldn't detect that the first time he changed the coils..I dropped him....I'm going to infiniti and have them do it..
Thank you so much for your video!
I completed the job & it runs Great 👍
Thank you bro for this video .. i have g35 08 ist the same way when u losee the intake manifold bolts (With clock Wise reverse imean 😂.. its confused me
Good video, clear to the point.
Appreciate that Fam. Thanks for Watching
Thanks for the tips
FaSho👊🏼
Hey man I hope you can help me out. I have an 09 g37 base sedan. I put it new spark plugs, new MAF sensors, cleaned the throttle bodies, reset the ecu, and did the idle relearn. However it still runs like crap. Rough starts, idle all over the place, poor acceleration until about 3k + rpms. Could it be time to change the ecu ? Would greatly appreciate any help.

do you still have this car and did this stop the dripping on the garage floor completely? thanks, jim
Hey man ik this video was posted a min ago. But just curious how you got the bolt off that is hiding under the fuel dampener. Thanks!
Great video I’m getting ready to do this job soon. Did this fix your P0300 code? Mine has it too. Thanks in advance
I'm in the same boat
Awesome video! Very detailed. I bought all the parts but after seeing this i don’t think I can do it. How much would you say is a reasonable amount to pay for this job? Please separate Labor and parts.. thank you so much
Hey Fam I appreciate that. Now it’s about a 3.5 to 4 hour job in the book. So all you really need to know is how much the shop charge per hour. This can vary from shop to shop. It’s not that hard to do. It’s just a lot of hoses and wiring harnesses to move out the way. It can be done by yourself but you’ll need someone to hold harness out the way on install. Other than that I used wire to hold shit out of my way. Just have the proper tools and it can go smooth. I changed spark plugs too but didn’t film that. Good luck. 🤟🏼
Would oil leaking on the plugs cause the car to go into limp mode? I have bad VCGs and I'm waiting on new ones and spark plugs but a week ago I went into limp mode shut the car off turned it back on and it was fine
Hey man, sorry I'm back with more questions. Your video is quite good so I can't help but ask and I'm trying to get the correct parts ordered.
1. What torque wrench are you using? I only have a large one for tire lug nuts, but need a smaller version for jobs like this.
2. What cleaner/solvent are you using @13:09 to clean covers?
3. On the G35, the seal/gasket at spark plug tubes are integrated into the valve cover themselves, but it it looks like you were able to replace yours at 14:01. Is that correct? Maybe this is something new for G37 which prevent having to replace the entire cover if oil is getting into spark plug tube.
4. Other videos report of a "valve cover breather Hose" cracking due to it being brittle. Did you have any issue with cracked hoses?
Thanks again!

The plug gaskets are replaceable just made differently. Same steps tho. If you got stock hoses, you might want to replace them. They do crack with age. You’ll get a vacuum leak if you let em go to far before replacing. I got one that’s cracked but not enough to cause a leak yet so it’s on the list of parts needed. I did use a water hose and my detailed brush to agitate the degreaser then I air blew it dry and let it sit til next day. Just didn’t want any moisture left inside. All you need is some degreaser water & some rags (towels). I got those scrubs from a friend who get it from work...Hope it help bro. Good luck with it..just get in there and you’ll figure it out as you go..The video will just be the guide you need to get it done..I’m no mechanic by any means.
@@tgreen200 thank you! Much appreciated!
Great video, where did you get the instructional pages from? Please link thank you.
Links down Fam. When I found it I downloaded all of it but it’s not there anymore..Sorry. Thanks for Watching 🤘🏼
How many miles did it have at that moment? Did you have oil in any spark plug tubes?
An advice for anyone wanting to do this, It's also a good practice to change the long part of the coilpacks as well once you are there for the peace of mind, they cost about $50 for a Denso six pack.
What’s up Fam I was at 240,000 miles when I did this work. I did have oil on the boots, I had seen this at least 30,000 miles before I changed it because it didn’t present a problem at the time. So I continued to drive her an the day before I was going to just do the work she decided to fail completely. Misfiring on one cylinder on the first start up. Then on the second start up she misfired on multiple cylinders. I had scan tool hooked up after the first misfire. Lucky for me it happened at home in the garage. I also changed out the plugs too. I feel there’s no need to change coils unless you’re getting a misfire. If the coil is failing you’ll most likely get misfires first because the computer will count all the voltage drops that fall out of range. An will throw a code after so many drive cycles. Shouldn’t be a hard job to do if you got tools and a good back..Thanks for Watching 👊🏼
@@tgreen200 wow that's a quick one answer! Dude they lasted A LOT! I've got 101,000mi and I have everything to do it because I was about to change the first spark plug (because I pit a supercharger) and I saw the gasket bad in there. No oil but I saw it, probably started an oil leak in there after removing it and touching the gasket while doing it (or maybe not). Too bad I didn't do it when I changed my lower intake manifold and injectors one month ago.
Yeah that sounds like a bummer. Well if you got any oil in there then you got a leak at a seal. Nice G BTW🤟🏼
Hey by any chance where would I be able to get those Instructions? I gotta do a valve cover job in the next few weeks
I just saw a comment saying the site was taken down. Would you be able to email or dm them to me ?
Hey man, i just found oil on one of my spark plugs and im at 120k miles with a random misfire im assuming this is my problem.
but im trying to narrow down what it could be, did you change the coil packs and spark plugs again after you change the valve cover gaskets or did you reuse them>????
all said and done this fixed your random multiple misfire??? you said your car failed at 250k miles? wow you have a legendary motor xDDD
What’s up bro. I only change out my spark plugs, because it was almost time and I was already in there so I changed them. Coils was fine. But if you got oil on plugs then you probably need to change out the gaskets and plug gasket too. You might be able to get away with just doing the gaskets and not the plugs. Just clean em up they most likely will still work just not with the oil on em...Thanks about the motor. She’s holding up for a old G....Thanks for Watching.
@@tgreen200 thanks for the reply man just ordered 100$ of gaskets to do the valve cover rebuild. we finna see. hopefully i dont have to get another set of spark plugs or coil packs again. the last time i did only spark plugs and mainly found oil in 1 or 2 plugs and coils
Sounds good. I believe you’ve solved the issue with the misfire. Let us know what happens. I appreciate you. Thanks again for Watching
@@tgreen200 i hope so i got a p0300 and tbh everything is tight and i have test pipes but extensions ive never received a CEL until i pulled my plugs it became more frequent after like RN the CEL is off but come tomorrow it will surely turn back on
@@SHELBYGT645 yo how’s your g ?
Do you think it’s best to replace the plastic valve covers too? Or re using them is fine ?
Im at 150,000 miles i just replaced mine for new ones and powder coated them gloss blue as and extra.
P1233 P0228 P2133 I got these codes any suggestions on fix
Great video! I'm looking to replace valve cover son '08 G35. Where do you get the spec diagrams? Please provide source link. Thank you!
Thanks Fam. Unfortunately they took the site down.
Did it run any different? Trying to track down an issues with my 08 6mt g37, had a CEL for random misfire, and car seems just slightly down on power sometimes. Exhaust also sounds like it has a slightly different tone. Its uprev/motordyne/gen 3’s
Sorry to hear that. I would start by checking for vacuum leaks. Usually it’s around the TB, intakes, pvc hoses, any hose connected to the upper intake collector. Or spark plugs could be fouled. Just remove em to check. Does the code just comes and goes? Could be coil about to fail. If you haven’t changed valve cover gasket on a high mileage G u should do all on that and change out to new plugs too. Let us know what happens. Thanks for Watching Fam
@@tgreen200 its only 45k miles, plugs were only a year old but changed them anyways going from denzo to NGK with no change. CEL only came on once, i cleared to see if it would come back and it hasnt. But the car feels off, less power (inconsistently feeling between 70%-90% power). But motor feels like it runs a little rougher as well. Like not horribly but a little. And it was and will every once in a while idle drop (stutter) at stop lights.
Bro sounds like to me you got a vacuum leak. You got stock air box or aftermarket. If stock check the plastic breather it has two hoses connected to it one is on the intake and the other on the valve cover. It may be cracked. I replace mine along time ago due to it creating a cel and rough ride lose of power and fuel trims was way off. I would check the fuel trim if your scan tool has a drivability function..You want to selective live data and let me know what you got. This will definitely tell us if you got a vacuum leak because you’ve rule out some other problems. Let us know Fam.
@@tgreen200 hey sorry just saw this now, it has Stillen Gen 3’s. And i dont own that kind of scan tool sadly, but i can look into getting one.
Will this work for a 08 g35 hr
It’s basically the same procedure. Thanks for Watching Fam👍🏼
in process right now, waiting on new driver side rocker cover, mine cracked when removing bc im a bone head and did not remove screw dead in middle of cover. SMH and was prying on cover it cracked. any ways.... while moving wire harrness, did you unplug all the way down to the a/c compressor? on driver side. Reason i ask is that plug is being a lil ahole. I see in your video your harness is a a lot looser than mine. Removing bracket that holds bigger harness is a + and i will do that but is there more to the harness loosing?
Sorry to hear that Bro. You really don’t get anymore room if removed. Them other wires run to far to get to so what I removed was enough. Just need to remove that bracket for sure. That’s the main hold up. Hope you get it back up and running soon. Thanks for Watching Fam.
Cover should be here friday.... catch can too.
Cover on, plugs and coils in. Both sides, by the way. Now just researching the TB re learn bc i cleaned TBs all out.
That info is in the vid. Did you get it running?
@@tgreen200 oh yeah, all is gud. Shes my daily.
Man can u do Myg37
What is that tool you're using to get screws @7:55?

Thanks for Watching Fam.
@@tgreen200 Perfect. Thanks so much.
What mileage you were at when you did this procedure
245000 when it failed completely..probably should do it at 100k..Thanks for Watching Fam.👊🏼
Did you reuse the plastic valve covers?
Yes sir I did reuse them. Thanks for Watching..👍🏼
Thanks for the reply.
Is it the same process for a 370z?
Fam I believe so. Just have a strut brace to remove. Thanks for Watching 🤟🏼
The same for sedan ? G37 rwd ?
FaSho👍🏼 Thanks for Watching
Thanks bro
