I don't know about the M55, I have the M155 with a Canton Oil pan. 25psi at idle, and 60+ at high RPMs.

Only issue I had was that the oil was spraying onto ( inside top ) the valve cover hard enough for it to leak out around the seal of the back breather port and onto the header, so I had to use RTV to ensure a good seal.

I hate breather caps, they are useless. If you didn't have the breather it wouldn't have leaked.

I'm gonna go out soon and get a new:

Opti
Plug wires
Waterpump
Intake manifold gasket
Timing cover seal *gasket*
Oil pump

Should cost me a hefty amount.

Just go to thunderracing.com..
