Okay..

Leaked the motor down.. All's well there.

#2 cylinder intake valve lash was set wrong.. Reset and it came right back up to the other cylinders.

Cut open the oil filter and it was clean..

Going to pull the pan and check bearings.. Better safe..

Drained 12qts of oil out of a 10qt pan and filter..

Couldn't possibly have sucked the pan dry..


Question

Could losing oil pressure at top end be attributed to the bypass valve in oil pump cover??

Pressure came up immediately after lifting at top end..
