put a pressure gauge on the motor would be a way to test lpop.

I believe there is a port down by the oil filter that you can test the LPOpressure...

If it's bleeding down, you could have some O-ring issues..

Sub'd. I have a feeling mine bleeds down as well. Starts kinda hard for 156k miles and somewhat fresh batteries.
