Throttle Body O-ring repair/replace with PICS
The pics are pretty self explanatory. You will have to remove the Y-pipe and anything else in the way of the TB coming off of course.
I did this with the TB still partially attached by a few large VAC hoses near the underside of the TB. I placed a towel underneath the TB to catch any parts that would otherwise fall into the engine bay. You can undo the VAC hoses and completely remove the TB out of the engine bay if you'd like. Also Between pics 3 and 4 I removed the butterfly valve and shaft from the TB to get the old seals out. The seals may be a little stubborn to get out. I used a precision screwdriver(the ones for eyeglasses) and a rubber mallet to tap them out. Then just put the new #7 or #8 O-rings on and and reinstall everything the way that they came off. IMPORTANT EDIT: In the 4th page of this thread someone wrote that the #7 Home Depot O-ring by itself may not seal the TB shaft tightly enough. The #7 O-Ring can be used together with the old stock seals, as in stuff the O-ring into the old metal seals, to get a better seal. Also the #8 O-rings from home depot were mentioned as a better replacement if you are just going to use O-rings alone to seal the TB shaft. IMPORTANT EDIT: The screws holding the butterly valve together strip extremely easily. These are the screws in Picture #3. I nearly rounded out the screw before I went to Sears to get a 35 piece screwtip set. Nothing worked except the Philips size p1 tip. By the time I tried this tip there was almost nothing to grip onto on the screw yet it got the job done. So if you're having problems here go buy just a Philips p1 tip if you can.

These leak air... As in boost ...
BucknVR4: You have fuel in your TB?? Do you have secondary injectors or something?? If your set-up is even close to stock, you'll never have fuel any where near these o-rings. |

). But why not just bump the boost up a tiny bit co compensate for the leak? I'm allready pretty much maxing my injectors out and my turbos have more to go.p.s. Subscribed, I have been thinking of doing this mod. And to the thread starter, can you take measurements of that o-ring with a caliper (or as good as you can w/ a ruler) for those of us who don't have Home Depot, or dont want to buy theirs? (I can get any size o-ring from work, nitrile, silicone, viton, neoprene, etc.) |
