Why are you bumping, you never reported what happened with the boost leak

I'm about to do a boost leak test tomorrow, and how can I keep from presurizing the crank case? I read that I could take the oil cap off. I just want to do it right the first time.

do you not read other ppl's posts? u are over looking the right info posted in here.
maybe u should try out a thing called reading.
oh and u still dont have your vac lines run right either.

When checking for a boost leak I've always used starter fluid to find it. Gotta spray everthing. Couplers, gaskets, seals, the works. Also you definitely need to be sure your timing is set right and your car is idling at 750 at normal running termperature. Maybe your pcv valve? That could be the culprit.

Alright, I installed a new thermal intake gasket and fixed my vac lines, how I have one for fpr, one for boost gauge, and one for my bov, as for the WG, I drilled a hold in my hot pipe and screwed in a fitting, now my car runs great and i got proper vac.

But now i'm over boosting.... could my fitting be leaking?

A boostleak test would confirm this! lol

You might be facing the all debated internal waste gate suck syndrome!
If you have an ebc, it can be tuned out! or you can go external.

Yeah, I def need to do a boost leak test, also I dont believe the WG is stuck, I can move it a tad by hand, but i'm going to check it with the air compressor. But i'm def glad I got normal vac and its not breaking up under boost.

Not Stuck! LOL!

What does that mean lolol.

jr_ss · 01-13-2013, 10:27 PM

It means they are prone to boost creep...

rwtf · 01-13-2013, 11:13 PM

by that much? I would see maybe up to 10 psi, but 15?

rwtf · 01-14-2013, 05:53 PM

found out actuator is messed up, I blew into the hose going to it and makes a whistling noise and there's not actual pressure, it pretty easy to blow into, so i'm gonna get another actuator from a buddy.
