4.3LX oil pressure?

[mattie_k]

The other day out on the lake I noticed that my oil pressure gauge was reading max ( it goes up to 8 and was reading over that) while I was cruising at about 3200rpm. So I kept a close eye on it all day, at idle in neutral it would read around 4 psi in gear at idle it would drop to 3 and any time any more throttle was used it would spike up to max and stay there. What is the normal range for this motor? Could I have a bad oil pump?

Re: 4.3LX oil pressure?

Before you take another step - confirm the readings with a remote guage (beg, borrow or buy).<br /><br />3 or 4 PSI is way too low and pegged out is way too high. Could be a faulty sender, or worse .<br /><br />It goes without saying that you checked the oil level, yeah? <br /><br />Aldo

probably 30 and 40PSI if gauge pegs at 8, thinkig 80 PSI. ---its still early---just a thought

The oil is good, fresh and the right amount. Guess I need to figure out a remote gauge then...<br />still don't know what its supposed to read though.

What year is your LX and what is your gauge reading in, PSI X10 or Bar???? <br />Most newer V6's should have 30 to 55 PSI at 2000 rpm.

cold its going to be higher,probably around 70psi-warmed up --30 is about lowest---thicker oil is going to run higher psi---use correct oil for your engine.

Sorry Don, it's a 1996 reading in PSI x 10, thanks for the info though! <br />Lowshovel1 I use the Quicksilver oil for my engine, I'm a little picky.
