This may be a stupid question, but, when I am running hard what should my oil pressure be? I noticed yesterday that it was all the way up at 110.

 

That really depends on what you are using to see the oil pressure? Is that the stock gauge? If so than get an aftermarket gauge or a mech. oil pressure tester for about $20.

However, if you are using some aftermarket pressure indication 110 is rather high for a stock 2nd gen. I believe there is a releif valve that lets oil pressure go around 70-80psi.

It is the stock gauge and I just got a 87 non-turbo, noticed when I am really redlining that the pressure reads that high on the stock gauge and I was just wondering if that is OK.

 

I just went thru a big ol deal with mine, except in the opposite direction - low oil pressure.

I also have an 87 n/a. Anything above 3K on the tac should only read 60-65 psi. There's an oil bypass valve that, when working properly, doesn't let the pressure get higher.

The stock gauge is notorious for being inaccurate. You need to verify your reading with mechanical OP tester first.

 

Mine reads 10 at idle, 40 at highway cruising, 50 is i am lucky. When it is summer and I use 20W50, it gets better

 

sounds like yoou need a better o/p gauge. it should read 60 when cruising and 30 when idling. 10 at idle is low that must be some super thin oil your using. with 20/50 mine was at 30/idle and 60/cruising. when i switched to 15/50 i get 20-25 at idle and still get 60/cruising.

 

10w30 castro. not really worried about it. been like this for 80K miles

 

yeah, no worries your up in the cold weather. im in HELL!!!!! its so ****** hot out here!!!!

 

i love my ac

 

a/c.....how cold is it up there? this time of year you need a/c?

yeah a/c is ok if you wanna go slow and waste even more gas!

i like a/c but my rexy doesnt! slows her down! she likes SPEED!!!

 

Say he got the gauge and it reads high, what would cause the abnormally high oil pressure? Would it be bad for the car to have high oil pressure?

 

gets to about 90 here in the summer. I used a/c last year everyday on the highway....

 

the regulator not bypassing would cause a high reading i would suppose! other than that maybe a clogged oil hose or somethin.

racing beat says all you need is their opr which bypasses at 85. anymore is for racing engines and not recommended for the street. somethin about the engine not being designed for the high pressure.

the 13b REW is another story as that engine comes from the factory with a opr that bypasses at 100 or so. but the oil passages are bigger.
