So...I got a bitchin boost leak. it sounds like a whistle..or a little girl scream.


and..i cant find it..which pisses me off.


Its probably for my boost gauge.


Thought i'd share.

 

damn, mine last 2 boost leaks were at my #2 injector and intake manifold gasket. did you try the choke cleaner trick yet on your injectors and manifold?

 

Shitty!

So far no problems here!

Hope you find the leak!

 

dang... i didn't know we had so many 2.4l turbo'd guys.... now i feel EXTREMELY slow..

 

lol last car i had that had boost leak i had to sell it because i couldnt find he ****.

 

Im pretty sure its the way i rigged up my boost gauge.

That shitty plastic nylon tubing is well...shitty.

So i put teflon tape around part of it to seal it to the hole in the nut for the gauge, then i put a slightly larger vaccuum tube which the nylon tube fit right into it pretty snug.

So i think i'll go through the motions today.


I'll have to check out my #2 injector to make sure my o-rings are still cool.

My boost is all over the place though.

It peaks @ 10psi, then drops to 8psi.

so im sure its a boost leak. plus the faint sound of a whistle type noise.

 

where can i find the orings for the injectors and also the oring for the sleave that covers the injector i have 2.2

 

theres an o-ring on the injector itself, then theres one actually in the seating as well.


Your better off calling or going to a dealership.

 

yea i went to the dealer that would only sell me it as a kit with injectors , etc.

 

im sure its just a universal o-ring. get the size of it...and voala.

 

i had a similar problem with my coils. theres an oring there, and the dealer wanted to sell me a new ignition and im telling the dude, no no man, i need an o-ring. supposedly they aren't sold separately, so i went to home depot and got one there in the plumbing dept. works good.

 

Ya, O-Rings are O-Rings. Cost a few dollars for a package of 20.

You should be able to get them from autozone or any other parts store.


GM is kinda weird like that, back when i was going to do the dual exhaust cutout, i wanted a stock SS 2.4 exhaust tip, and they told me that it comes paired with the muffler only.

 

I had to buy the embossment o rings as a 1 piece with the rubber o ring and embossment for like 420 from the dealer.

 

i found my boost problem, it was the way i rigged up my boost gauge. Part of the vinyl tubing pinched, which didnt make a nice seal.

so i cut it, replaced it. and zip tied the **** out of it.

great stuff now.

 

What PSI are you at on the gt2860rs?

 

(this is turbo06sedan). Im at 8 on some gears, 10 on others.

 

wow, i never noticed different ammounts of boost for each gear. i have noticed lower boost in hot and cold weather though.
