what psi is it doing now?
money is on the o ring.

It stayed at 12 for maybe 2 seconds, then picked up to 15 and then i left the light. Got to work and it idled at about 17-20.

It ran at 30-35 hot idle at the beginning of the week. Doubt the O-ring can change it's orientation in 4 days.

Worth a try before tearing into the front of the engine i guess. Would also give me a chance to cut the filter and take a gander at what's inside.
