Testing Vacuum Chambers
Before we rip out the turbos, I want to check to see if the vacuum chambers are working properly.
Is there a simple test for these?
Thanks for any help

Mityvac is the tool you need. Worth its weight in gold. Get the MV8500 kit.

Also, if you haven't...check out the FAQ thread in this forum and look under "T" for turbos and you'll will find some excellent tutorials on troubleshooting turbos and checking components. Priceless info. there.

That said, if there is not a rush of air, the chamber is not necessarily the source of the leak. But the test above is not nonsense since in most cases the tanks themselves don't develop leaks. It's usually a check valve, hole in a hose, or sticky solenoid that drains the chambers.
