Lets talk about FD oil pressure regulators

somehow that doesn't much surprise me.

What are your pressures like? GENERALLY when an o-ring blows out the pressure is abysmal. Not sure why mine continues to seal

it's not a current problem. i had a blowout with that car and crashed it a few years back. the engine has been sitting in my garage ever since. it's just that i was never able to figure out what was going on.

from what i remember, idle pressure was normal. it would shoot up to about 80 psi (stock gauge) with throttle and just kind of sit there through the gears, but once i was cruising on the highway, it would slowly start falling. it never got critically low though. keep in mind, for most of the 2 or so months that it ran, i was limiting myself to 4000 RPM because of break-in on the new bearings.
