Thanks to this write up, i just completed this job. The PCV valve hose was self explanatory. I also didn't put in the spark plug guides until after i put the valve cover back on, and they slid down pretty easily. It made it a hell of a lot easier to replace the valve cover without them.

I wanted to say a big THANK YOU to the OP for this excellent DIY. I read this whole thread and felt more than prepared to change my VCG. Everything went smoothly. No broken connectors. Burning oil smell in the cabin is gone.
The one contribution I'd like to make is the tool I fabbed to remove the three ground posts. I didn't have a 10mm deep well socket and apparently there are a bunch that don't fit anyway, so I took my 3/8" 10mm socket and welded it into a 6" piece of 1/2" EMT conduit that I had laying around. This required cutting a slit in the conduit so the socket would slide in, but the whole process took about 5 minutes and worked perfectly. I just clamped vice grips to the end of the conduit and used it to wrench the posts. |

What the hell kind of deep sockets do you guys have? I tried with my deep socket and it's no where close to fit on it.
Also my wiring harness bolts seem to be steel and not aluminum? Odd. |

Doing this job right now FYI at 72k miles my PCV holes are perfectly clean. I can't confirm if valve cover is 100% (no service records before I bought) original.
Valve cover has the factory stickers so I'm 80% sure it's the original. I guess it all comes down the the oil changes that were done previously. |

Planning on doing this too after getting a CEL after a WOT run and having some real harsh idle that went away after driving for a bit.
Read the code for a misfire, pulled the spark plug and found oil in the well. Thing is, I'm only at 35k on the odometer 😂 on the joy Thanks OP, pics will come in handy soon |

Just did this service yesterday on a N54 Z4 35i. 75k miles. All in all it went well, but somebody had been there before me. Plastic cable management clips on the fuel rail were partially broken, and some of the valve cover bolts were not tight at all, and some were surprisingly tight.
As a bonus item, when I was getting ready to put the valve cover back in, I noticed that one of the spark plug sleeves had a metal compression ring (c-clip on the bottom) missing. If you do this service, remove spark plug sleeves before removing the valve cover. I searched around the engine valve system and could not see it there. Not in the spark plug holes either. I re-assembled the engine and it seems to work well. Some ticking sound at idle (not when I rev it) but that can be either the direct injection or perhaps the new metal VTT PCV valve that I installed.. Time will tell but I hope the c-clip is not somewhere in the engine. The result is no leaks and very smooth engine operation! It seems that mine was leaking quite a bit, and now it even seems to have better boost control |

Just used the OPs write up as a guide, it left a lot of steps out.
ECS tuning one is much better for those looking to do this. http://bd8ba3c866c8cbc330ab-7b26c6f3...eplacement.pdf

Thanks for the pdf link. I’ve got the parts on the way and will tackle this next weekend. Ordered a crank vent hose just in case and also an upgraded PCV valve from Vargas turbo.

Just did this as a part of my rocker/lifter replacement job.
Excellent writeup, thanks robc! After finishing the job, I cleaned that aluminum channel where the oil was seeping, presumably from the valve cover. After about 50 miles, the channel is still clean. |

Finished the install yesterday, instructions were very helpful...
Had a moment of panic as I was putting back the fuel rain on that little guy somehow made it all the way to the bottom of the intake manifold and all was well after I fished it up. As a thank you my car decided to reward me with a broken cup holder. Hit a bump while driving; popped out and does not want to remain in closed position anymore. Oh well, one more project to deal with. |

So I just completed the valve cover replacement and I am having trouble screwing in one of the 10mm bolts (one closest to the front with the ground wire attached). The other one went in just fine but this one almost feels like its not lining up with the hole. Anyone else had this problem or any suggestions. I really don't want to pull the whole thing apart...
I can get it started and everything looks good, but I'm afraid that the bolt being loose will cause some serious issue issues. I attached pics for reference Last edited by Yobroham; 06-28-2020 at 12:37 PM.. |

After getting everything back together and going for a drive, I have an active drip of oil on the ground when parked, which I didn't have before hand. I'm really hoping I didn't crack the valve cover when prying it off, definitely didn't sound good when I was trying to pry it off. Hoping it was just some oil that dripped out when I pulled the VC off, then heated up and ran down the exhaust. Reeeeeally hoping. I agree that getting every bit of the old gasket off was the hardest part, since it was rock hard, halfway stuck to the head, and came off in multiple pieces. Also, holy hell, neither this DIY or the ECS document prepared me for how hard it would be to get the spark plug hole liners out. I didn't have a set of small picks like ECS said to use. I had a set of small bent needle nose pliers, which should have been perfect to remove the liners, but they didn't work at all. I got one out and gave up, hoping to just pull the VC with them in place. I think it made getting the cover off much harder because I had to lift it a lot further off the head to get the liners to clear the injectors and everything else.

What is the recommended gasket to utilize?
Anyone have an experienced recommendation? Do they make a gasket that is utilizing a better material than the stock unit that hardens and cracks apart? |

I realize this is an old thread, however for those that purchased new valve covers-
Which brand did you pick/recommend? Seems there are at least 4 brands available today. |
