Default no boost...oil in intercooler...HELP!!!

i'm not boosting anymore! i came home from work one day and the car drove fine...i drive again 20 mins later and it's not boosting at all...i checked all the lines and everything looks normal and intact...so today i take the intercooler off only to have about 1/2 a cup of oil spill out of the opening that connects to the manifold...then i set it down and take off the Y pipe and another 1/2 a cup of oil leaks out...i know it's normal to have oil in there, but that much? so i bought some brake cleaner and cleaned it out and it's drying right now...has anybody else experienced this, or have any idea why this is happening?

i'm thinking there was too much in the intercooler which was clogging the air flow, prohibiting any boost...my friend said he had the same thing happen to him with one of turbos in his vr4...his second chamber in the turbo went bad, but he had a number of things happen that lead to this like whining noises and bad smoke...i've no warning signals at all...no sound, no smoke, no signals...i really don't want to take the turbo out and get it rebuilt

i'm running a vf30, turboback exhaust, boost controller set @ 9psi...stock fuel sys

can anybody give me any insight or any advice? i need boost!! i'm like an addict feening! also, does anybody know if IHI has a warranty on their turbos? does anybody know IHI's website?

I am about 99.9999% positive you don't have a warranty on your IHI turbo.

On another note, do you have an oil catchcan? If not, one may help keep your oil pooling in the can instead of your IC. Whether you do/don't, if the turbo seal is shot you will not avoid oil in your IC.

The oil in the ic might be the problem, but since you have it off and the cars just sitting there might as well take the turbo heat sheld off and check the waistgate. If its stuck open youll get no boost at all.

You should be able to move it by hand, if you cant that might be the problem. Also what kinda downpipe do you have, if its one that has a divider for the waistgate gas, the flaper might be stuck on it.

i tried moving the rod the wastegate and it doesn't budge...i put the intercooler back on went for a test drive...one pass down the road and it's still doing the same thing - no boost...after a couple mins of driving, it starts boosting, but not normally...it sounded like a high pitch whistle (like a hydrolic sound) and it felt like it was being held back...so i think ok, we're getting somewhere...i turn off the car to get some gas and when i start driving again, it goes back to not boosting...i'm figuring something is definitely wrong with the wastegate...??? i have an hks downpipe...i don't think that has a splitter...i'm going to take the turbo off tomorrow and take a look inside...if i can't find anything wrong, the stock turbo's going back on

I had a problem with the car not boosting at all, the gauge would go up to zero and then stop. I pulled off the downpipe and checked to see if the turbo wheel would spin freely and it was stuck. So, I had to pull out the turbo and there was some type of hose clamp stuck in the tubine wheel on the exhaust side. I just spun it a little and it feel back into the turbo.....then just turned the turbo around and it fell out.
So, check the wheel and see if it spins freely. If it does then I would think it has somehting to do with the boost control.

Good Luck

sounds like the oil seal on your turbo could've blown....if you have your stock turbo, that's a good way to trouble shoot and narrow it down to your turbo

put the stock back on....and take a close inspection of the vf30

well...i took the vf30 off and i tried spinning the compressor wheel and it turned pretty roughly, especially compared to spinning the stock turbine...it spins, but i can definitely hear rubbing...so i put the stock turbo back on, and i'm going to have to take the vf30 somewhere to get it looked at...

after i got the stock turbo on and started driving...i noticed that turbo whine was alot higher pitched than i remembered...i hadn't driven the car with a catless turboback with the stock turbo though...is that normal with a catless turboback exhaust with stock bov and stock turbo??

I noticed that I could hear way more turbo 'noises' after I installed my APS turbo back exhaust (with the stock turbo).

I did some checking around, folks said that is normal.
