Hi,

I just put oil pressure gauge on my gen 2 3sgte..
Seeing pressure's off 25 psi max with 100 degrees temp. :shock:

When she is cold i got 85psi with a bit off rev's
And 25 @ idle..

Hot 20 @ idle and 25 max with revs....

What can i do?


Measured on a remote oil filter, which is in a oil cooler loop with a 80 degrees thermostat( all mocal)
 
That doesn't sound that bad to me...especially considering that it is being measured through a remote oil filter. Pressures would read higher in the head where the stock pressure gauge gets it signal from

Seems weird.

I would pull a bearing cap to inspect for damages. If nothing is found replace the pump, it may be that the pressure relief is bad...

wait a minute. is the engine dead vertical or on a lean? i wonder if you are having a starvation issue. put in an extra qt and see what happens.

Its on a small leen...
bottom of the sump in vertical.

For now I only took the sump off.
bearings look fine.

I got a 5s oil pump coming. .

Going to pull the old pump apart to see if I can find something.

It have not worked as I hoped. .

got a 36 psi now at the most.
its @ 25 on idle... so that more then fine. ...

just as soon as I rev the engine its got 35/36psi @2k rpm.... that where it stays.

Bearings look fine.. so since of waer..
did not messuage them.

how to go from now?
