If the check valve on the AIR system fails allowing exhuast back on the pipe to the diverter valve, what will it do to the system??
Will the AIR by pass valve just dump it or will it back up in to the vac system causing other problems(like low vac and/or over boosting)?
I see how to check the check valve, but nothing says what a bad one will do to the system.
I ask because I was checking for vac leaks and I removed the pipes going to the check valve and saw some black soot in the pipe. I did think much of it until today after picking up my car at a buick dealer, I had them try to find the leak/problem.
I have low vac at light take offs and under light loads(going up hills on the HWay)
At a stop under heavy acceleration boost only goes to about 7-10
(I have it adjusted low)
But when I'm cruising and step on it, boost will climb above 12 before I have to get out of it to stop from over boosting.
I know that I have a problem with my TC some were too, it engages(got it sp) & disengages at will and I can not manually keep it locked.
