Yes, there are parts lists out there, but I figured I'd both bring some more content here and get some answers to some questions I have at the same time.
Anyway, my intake sure seems like it could use some attention. The car runs fine (at least as far as someone that's only driven this 928 can tell), but there is certainly some oil leaking into the valley and all over the throttle body.
The intake just looks plain ratty at this point too.
I certainly will be replacing the intake gaskets. I already have paper ones that someone gave me, but I think based on serial number my car might have the metal ones. Are the metal ones really worth the $300-$400?
I want to replace all of the rubber sleeves and orings joining up the different parts of the intake system too. They're old, cracked, and nasty looking. Replacing things like the small vacuum lines makes sense too.
Not sure if the ISV or TPS should just be changed or left alone if not seeming to give problems. Sounds like the TPS can be tested, but not sure if that's true of the ISV. Idle seems to be stable at around 800-900 rpm for what it's worth.
What I'm hoping to find out though is do you really need to get things like original molded pcv hoses? This car isn't an all original/concourse winning/etc vehicle. It's a high mileage driver. So if I can just use normal vacuum hose for stuff like that rather than $50 per hose to go from the cam cover to the intake, I'd rather go that route.
While the intake is off, I'll of course repaint it. I'd also like to replace the cam cover gaskets and inspect the timing chains and tensioner pads.
So far these are the parts I'm planning to get. Hopefully someone can help me fill in the blanks.
paper intake gaskets (have already) - 928.110.568.00
8 small runner seals - 928.110.343.00
2 large runner/"T" seals - 928.110.347.00
large maf oring - 999.701.699.40
small maf oring - 999.701.183.50
maf sleeve - 928.110.243.02
throttle body oring - 999.701.436.40
throttle body sleeve - 928.110.248.03
8 sets injector seals - 944.110.901.00
vacuum hoses and elbows I'm hoping can be off the shelf parts unless they must be molded to locate things or something
2 cam cover gaskets - 928.104.447.06
8 cam cover orings - 999.701.731.40
26 cam cover bolt seals (not sure if these are correct) - 928.104.115.02
So what does everyone think? You can tell me I'm an idiot if I am.
