Throttle body shaft seals question
So how hard is it to change these buggers out just did a boost leak and I only had 2 but this one leaks pretty good should they not leak at all or do the leak a little if I push on the cable by the throttle body it pretty much stops 100% and my hole system holds pressure...
From the looks of the guide it doesn't look to bad I mean I've done cams and stuff like that it can't be much harder then the cam and timing belt job...
I was going to order the works seals unless there's better ones also what I can't find is should they not leak at all or do the bleed some normally ?

its not too bad, you will want to drain the coolant though before you remove the throttle body. After i did mine, they did not leak at all under 30psi test pressure. While you are at it you should probably replace the BISS screw O-ring and the o-ring on the IAC warm up flapper.

I just did mine, somehow they are leaking again, I did not however need to drain my coolant, a little bit spills out but not enough for me to drain the system. I am debating now if I should give it another go or leave it alone for now. Its easy enough, hardest part for me was finding small enough spring clip pliers. Ill tell you this, make sure to get HIGH PRESSURE SEALS from STM or mil spec. I replaced with OEM and I think that was my problem

I've had works on mine for like 3 years now with no leaks. I have a set from STM on standby but haven't needed em yet.

Get some throttle body shaft seals that's probably what's leaking along with with a biss screw o ring. You can get everything from extreme psi great price fast shipping.

don't forget the warm up flapper o-ring. I see you have an 04 so you should have one of these too. When i replaced mine the o-ring had cracked into pieces and it was spewing air.

as far as finding an oem one...i dunno i just had a large set of different size o-rings that i got from one of the generic auto parts stores and found one in there that fit.

Oh sweet man ya I have an ace hardware like 2 miles from me and They have a wall with about 500 different o-rings and sizes so I'm sure they will have it if I don't already
