Optional ICV for 928 S3 ?
I found these parts online and they both cross reference to the bosch and porsche numbers for the ICV * on a 1985 & 1986 USA S3. I have not purchased one - I thought I might need one so researched it. I have been changing the cam cover gaskets, and my idle speed adjuster appears to be moving smoothly, plus I found some suspect vacuum connections. But I searched around found two on amazon that look exactly like the Bosch part. They are being sold as fitting BMWs, but they cross ref the porsche and bosch numbers, and look identical. Perhaps they are cheap junk, but perhaps they are perfectly servicable.

I replaced mine with same Evans Fisher one but have big air leak and am 90% sure it's from this perished part but I can't figure out how to get to that clamp...

I have one from Roger that I used to replace one that had frozen open and was causing a 2K+ idle. It worked, but something was still off with the idle, so as a cheap test I bought a cheap (like, $28!) no-name from Ebay. It had a little American flag on the ad to make it seem like it was American made but I'm pretty sure it was just located in America when I bought it However, it worked just fine. Roger's was good too, whatever else is going on with my car is subtle and I haven't figured it out yet, but both of these ISVs are currently working. What I don't know is how long this cheap Ebay one will work. It does look identical to Rogers, and to the Bosch, for what it's worth.

Bureau13 did you change out the little rubber elbow that goes from the front of the ICV into the intake (on the '86)...if yes, can you tell me how on earth you were able to reach that clamp on the part that goes into the intake? I can't figure it out...not without pulling everything apart...

Hey Matt, It can be done, just not enjoyable.
I did the hoses and ICV without a full tear down.
It requires pulling side plenums and the larger intake T pipe coming off the throttle body.
To get your other hand in there pull the air box and MAF.
Easier then taking off intake manifold and fuel rails, but not by much.
Cheers.

"can you tell me how on earth you were able to reach that clamp on the part that goes into the intake?"
Loosen the hose clamps from all 5 ports and remove the right side air distributor/plenum. You can probably reach it then. If not, remove the big intake T. Use a Loooong screwdriver to adjust the hose clamps on the ISV hoses. You can also remove the airbox to further aid access. Stand on the left side, reach your right arm down to the ISV via where the airbox goes, and use the screwdriver in your left hand to tighten up (without overtightening, of course) the hoses.
Assembly is the reverse of disassembly
