I have a question on my 96 S10 2.2 engine. IN the winter when it
was colder, my oil pressure seemed always to be 40 or better and more
stable. Now that its getting hotter, the oil pressure gage varies up
and down more with RPM. It drops down as low as 20 at lower RPM, but not
into the red zone which i think is around 10 PSI. This engine has just
over 100K. I bought i used at 80K or so, and it had the head gasket done
before i got it.
My machine shop buddy seems to think the bearings are damaged, and that
i should run heavier oil in it now and get rid of it before the bearings
So, is this oil pressure level problematic? Other than normal 2.2
noises and some piston slap, it seems to run OK. Its not really burning
any oil either.
