I'm trying to replace the rubber mounts but am unsure of where they are...is one mounts to the V and the other two mount to the bracket on either side...i've looked at various pic of 928 throttle bodies and only see these
There are 3 - one on each upper side under the side tabs of the throttle body, and one down in the V under the throttle body "boat", which is tricky to reach (it is in the rear). Use a flat 10 mm wrench to get the nut off. Once all nuts are off, then you must yank very herd to get the TB off - it will feel like there are more fastensers, but there are not. You can use a tool for leverage to pry it up.
Note i have yet to locate long enough mounts from Porsche, vendors or other OEM. All the ones i have found are too short for the throttle cable bracket - let me know if you find the solution 😁
If your referring to the ones that Linderpat is showing, they are the same as use for the Air Box mounts, Roger has them in a universal fit, cut threaded shafts to length if needed.
thanks for the reply...so I don't have to take off the intake?
It is a '81 Porsche 928...I rebuilt the EFI and now the intake air box is 1/4" above the air flow sensor...
the mount as you can tell is completely flattened...
that doesn't look OEM to me. If the mount has sheared you will see a flat disc which was bonded to the rubber. Yours is domed as if someone just pressed something into the hole, not even a screw
I talked to Roger at 928 r US and suggested I use a screwdriver to "tap" it but maybe a thin 13 m.m. wrench will get it out I tried a mini-nail gun but it was too tight!!
No, that hex head is under the disk and does not come out - do not try. The way I have gotten those sheared disks out is with vice grips - grabbing the edges and turning it out. If that does not work, then dremmel a slot and use a screw driver. The disk is very thin. This sort of thing happens all the time with these rubber bumper screws. I do not think you can get it out without removing the boat (TB), and everything that entails. Are you due for a top end refresh?
