I need help!!! Oil Pressure

turbo4point6 · 07-02-2008, 10:48 PM

hook up my mech oil gauge and im getting 15-20psi at idle. when i rev it up a little it goes up what the freak is going on shouldnt it be higher?

do my valve springs have anything to do with it?

Your valve springs would'nt have anything to do with your oil pressure,worn cam or crank bearings or a worn pump would though..What was you oil pressure gitting up to at higher RPM's. 15-20 psi at idle is pretty good though...I heard it should be 10 PSI per 1000 RPM...

turbo4point6 · 07-02-2008, 11:15 PM

i revved it to 3 grand and it was at 30psi never went higher than 3 grand though

thunderchicken · 07-02-2008, 11:17 PM

Did you intsall a high volume oil pump??

turbo4point6 · 07-02-2008, 11:19 PM

it has the mmr one

thunderchicken · 07-02-2008, 11:31 PM

I was reading about those. Very excellent pumps. Yea thats pretty good at least if your at operating temp. Now there should be an increase in oil pressure also the more you rev the engine. So if it goes to 30 at 3000 rpm then it should also increase the more the rpm's increase. If it doesnt do that,then there may also be a bearing clearance problem. or clogged oil galley's,and or it just may be the pump....

well i guess im wondering whats the average oil pressure on mustangs ?

I dont know how old your oil presure gage is but maybe swap it out to eliminate it as the problem. Just a thought

turbo4point6 · 07-03-2008, 08:23 AM

i just bought one from oreillys returned that one and tried my dads old one and they show the same thing

as far as the stock one my cars a 2004 and that one is working now

turbo4point6 · 07-03-2008, 08:25 AM

maybe i hooked it up in the wrong spot? i hooked it up right below the stock eletronic sensor under the oil filter

As stated earlier, if the car is at operating temp, the pressure you're seeing is normal. Pressure is higher on a cold motor and drops at it warms up. Pressure increases with rpm. At idle, 10-20psi is correct on a warm car.

that sounds about right, mine runs about 15-20 psi when idling, but if i rev it it goes up to around 50 at 3k and driving around its around 60 at 3k in 5th. but the psi has dropped since its gotten warmer.

i guess ill rev it up higher and see if the pressure still rises
