Thank you for making a video on this!! I’ve been planning to do this to my 86’ S so I can powder coat everything. Issue is I couldn’t find a video or decent rennlist post to find all the seals needed. THANK YOU AGAIN, YOUVE GOTTEN ME THROUGH A TON OF MY MAJOR MAINTENANCE
@ 11:40 I think the reason they used that standoff bolt is to create an even force in the middle of the cam cover that will allow the gasket to seal around the head as the cam cover is not flat. If it were a straight bolt to the head then it would be very easy to apply too much force to the middle bolt and cause the cam cover to cave in the middle and prevent a good seal on the gasket or even crack the cover as the bolt pulls the cover to the head. Now why they didn't just make that standoff a solid part of the head and not a bolt? German over-engineering I guess.
You has some good luck with the bolts being loose. A lot of times this style ‘85-86 bolts can break. They changed to Allen heads on S4 models which poses their own problems. I also believe the factory used lock-tight on the bolts. Yours were probably off at some other time hence loose.
@@GuysWithRides1 Yes, is part of the “PCV” complicated way Porsche ventilated the crankcase. The later cars (like my ‘93 GTS) had oil consumption issues partially caused by this system. Different revisions were done up to 1995 the last year of production.

Alex - great assessment - thank you for commenting!
No pcv valve on 32 valve 928. Clamps on the intake plenum are 8mm.

buccicone fair point, but that hose is part of the crankcase ventilation for emissions, correct?

The corners of the cam covers should have driebond according to the shop manual. You can see the old sealer was on there after removal.
Ugh, I did not realize that. I have a feeling I will be doing this job a second time soon when I decide to powder coat the intake system.
Your a lucky man the bolts never snapped in the head what about the chain guide plastic
