Hey I own a cobalt ss 2009 and lately my car will stop boosting completely or only boost 5 psi I wondering Could anyone tell possible places where my turbo could leak from ??

 

Check your intercooler for cracks and do a boost leak test. You'll find exactly where its leaking.

 

People need to stop asking this possible leak question or saying I looked and checked for leaks and saw non. No, not the way to find leaks. Get a boost leak tester, it's a must on a turbo car, then check for leaks. Possible peaks are at every sensor hole and every coupler , every weld point or every plastic part. See how that doesn't narrow it down? Lol op invest in a boost leak tester and u'll find ur leak in 5 minutes
