why am I loosing oil pressure? HELP PLEASE!
--------------------------------------------------------------------------------
I went to the track today and I noticed by my last run and on the drive home when I started pressing the throttle and the motor started loosing vacume approching boost the oil pressure would drop. as soon as I let off the throttle the oil pressure would come back up. its still lower than normal though. it will be around 40psi with no throttle and 20 hg of vacume, when the vacume drops to 10 or lower the oil pressure drops to about 20 when approching boost. normally im around 40-45 @ 20hg and pressure increases with rpm. I was playing around a bit today with my breathers today, am I pulling oil out of the crankcase? or did I hurt something, the car doesent seem to be running as smooth either. almost wants to stall at idle. Im going to pull plugs later. also the oil is a little bit old. probably 4000mi, and Im running meth injection.

sounds like you might oil pump might be going bad but you also say you found some oil on your breathers sounds like you have a lot of pressure on your crankcase and its blowing oil up to your breathers, but that would mean some of your rings aren't sealing right.You say you vacuum its a little lower then usual you might have a vacuum problem also and that might be causing your car to idle rough and die.What i would so it do a compression test and see what you get and let us know.
