So say someone has low oil pressure, can you chagne the oil pump and be ok? :mad2:
I know at the place there were a few that ran into just that problem. They would install the 92-96 pumps in the 97+ style blocks with squirters in them which obviously gives low oil pressure at almost all times. There were one or two where they found missing oil galley plugs in them as well, not to mention the fact that they use RTV to seal almost everything on them instead of gaskets.
Well you could pull it , look it all over, ck the clearances and r/r whatever bearings needed, put in a new 97+ oil pump, make sure all the galley plugs etc are correct.
Or wait for it to blow up and it kills the crank and block and everything.
Justin, I haven't actually read all the posts on this but have you actually put a real gauge on the motor directly where the sending unit goes?
a little off topic but could a guy put one of leroys ops extentions on and put a T inline and run an oil pressure guage off that?
If it were mine and I was on a TIGHT budget, I would drop the pan and pull the rod caps off and look at the rod bearings. If there is bearing damage the rod bearings are normally the first to show it. If that checks out next pull the oil pump apart and measure the diameter of the oil pump gears to see which style pump it actually is. The late model engines do hold low oil pressure at idle compared to the early non squirters, but it should still be able to hold roughly 10-12 at a HOT idle.
If I was gonna do that, I'd be looking at closing off the squirters... there was a thread on here a while ago where a member had problem squirts that dropped his oil pressure to almost zero. It doesn't take much, in the rebuild process, to mess those up.
I'll look for the thread...
You might want to PM turbovanman and see if he has any suggesions. He's a good guy.
