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.
