crank case pressure and vaccum

[behindthen0thing]

I have a vaccum in my crank case at idle but I'm wondering if I'm getting crank case pressure that could be messing with the turbos while im on boost.

The PCV should stop this i believe but i don't have a reliable way to test it at the moment.

Does anybody have a solution that could remotely measure crank case pressure while driving? I was thinking of a Bluetooth sensor mounted in on the oil cap or maybe getting a sacrificial oil cap and running tubing to a vacuum and pressure gage into the cockpit.

Anybody do anything like this?
