First off, new here so HI! Secondly, I have recently (past 6 months) become the proud owner of an '89 LX that I thought was stock, boy was I wrong. Come to find out she has a HC stroker... neways long story short: Oil pressure wasn't reading at all - this is all out of no where BTW I had taken her down the track a few time a couple of months ago. Daily driver as well. Had an aquataince look at it he suggusted the oil pump - after about 10 hours on and off my wife and I finally got the oil pump swapped out for a new one. Side note old pump was apparently an HV and the new one is just a regular oil pump. I had originally purchased a HV but when we went to install the oil pan it wouldn't fit :/ I have no idea. Now after replacing the oil pump and cleaning out the pick-up - took her on a test run: low oil pressure 10 idle & 40 driving. Before I was getting 15-25 idle and 55-60 driving. Now I am also getting really bad vibrations at about 3000-3500 rpms. Any Ideas???????
