I just did this mod. After about an hour or so I lost all boost. Car is fine but when I accelerate there's no boost whatsoever. Everything is installed correctly. There's some oil on the bpv i don't have any idea why. Any help will be appreciated.

 

My suggestion, please start an new thread and add year, auto-manual, miles and anything else you have done to the car before this happened. Also, pull any codes although some times it may not throw a code. Oil in the BOV is somewhat common, read the threads about catch cans for more information.

 

Weird. I answered this new thread and it posted to the old one. Guess I'll wait till the mods get done moving everything.

 

Well. After reading the OP's other thread: https://www.chevyhhr.net/forums/ss-s...n-turbo-57501/
I can see he'll need to post up some history info before I'll try to guess.

Fwiw. 2 months ago he was having issues. He never bothered to follow up on that thread he started.

 

But if the first line of one of the DTC says "The P2261 diagnostic trouble code is an indication that the turbo/super charger bypass valve mechanical control circuit is giving the Powertrain Control Module (PCM) a reading that is abnormal. " Wouldn't you replace the BOV?

 

If he comes back we may be able to help point him in the right direction.

donbrew, thanks for starting new thread and moving post.

 

Wasn't me, I was surprised by it.

 

I moved this into a new thread.

 

Thanks OB

 

Your welcome! It was your suggestion.
