Oil Pressure??

[Guero]

My gauge only reads 25 and a steady 3000 rpm!!!????is that good??

 

[95Vert]

Nope! It's supposed to be between 40-65psi. Your pump is probably out.

 

[Guero]

you think that would be my problem???? with the noise?

 

[mackey]

It is probably a good idea to not run the car anymore if you are only getting 25psi of oil pressure.

 

[Guero]

i know. have you seeen the vid?

 

[fordtech28]

Your oil pressure has to do with that noise its not supplying enough oil and its running dry I would not run the engine any more before you damage it more sounds like the oil pump is going out for your sake I would tear down the whole motor apart it sounds like a pretty bad rod knock and the fact about the oil pressure will make it worse

time to pickup either a used shortblock (if you get a fox they have forged pistons, better for your nitrous) or rebuild yours

 

[Guero]

rebuild mine would be better, that way i dont have to have to take the heads of. ****ing bull****

 

[HISSIN50]

Guero, if you prime the pump with a drill, how does the pressure do?

You got good quality gauges IIRC (Autometer I think). Just checking.

 

[Guero]

yeah autometer. and prime the pump with a drill?????

 

[Guero]

ok at idle the pressure is at 12 and 1/2 psi. what should it be at idle?

 

[urban96]

warm idle should be above atleast 25

 

[Guero]

ok so im half of that, but i got good news, my dad said to take it to a mechanic and he'll pay for it!!!!!!!!

25 psi at 3,000 IS low, but not horrible. A general rule of thumb is 10 psi for every 1,000 rpm. That's on a stock engine though.

 

[Guero]

yeah mines not stock at all lol except for the block lol

 

[mytight95]

i have 22 lbs at idle with a brand new pump, so i don't see where 25lbs at idle is the norm, i ask a couple builders and they said it was fine. I have around 60psi at 3k though

[Guero]

so your gauge reads 60 at 3000 rpms?

 

[blksn955.o]

mine reads 55-60 at idle with a std. volume oil pump.

Low psi with a knock...it does not sound good man.

Best of luck

 

[Guero]

is it hard to change it out? my friend with a cobra pump(not sure if theres a difference but its in cobra block) said hell let me have his.

 

[Methodical]

Yeah I've talk to others who have said that they've had 10psi at idle and that's not a problem. Ford's gauge light won't come on until it's less than 5psi. For me, I'd be concern especially if you are having knocking sounds in the engine. Personally, mine is at or above 25psi at idle and I complete the rebuild of my engine in May '05 (only about 2300 miles on it) so the pump is fairly new. One thing I noticed is that the oil pressure with Synthetic oil is less than with Conventional Oil.

If and when you do rebuild don't be temped to install a HV oil pump unless you change to a 7quart oil pan - it would probably suck the stock pan dry to fast. Just One Man's Opinion.

Peace
