Do 88 stangs have a oil pressure gauge in the instrument cluster? Check that if you have one. If it's all the way down you probably lost your oil pump. Or the sending unit could be bad. ![[Confused]](confused.gif)

Go buy a cheap mechanical oil pressure gauge at Kragens and hook it up. If you got oil pressure, it's not the pump.

oil pumps don't "go out"
something else is wrong, drain the oil, pull the oil filter, cut it apart, and use a magnet to check it out for metal...

I've had one go out. The tolerances between the rotors and pump body got too loose and it just wouldn't build pressure once the oil got hot. At a cold start I'd have 40psi and once the engine got up to temp, I'd have 0psi at idle and 10psi at 2000rpm. I replaced the pump with a new one and never had a problem again.

+1 My oil pump seized on me. The oil pump drive shaft ended up twisted like a staircase and snapped. Found it at the bottom of the oil pan

something else caused both of those failures.

And what would that be? Regardless of what caused the pumps to fail, the fact remains, oil pumps do "go out".

I agree with wilit, we aren't arguing the cause of the pump failure. We're just saying oil pumps do fail. Whether that be because of an external issue or a problem with the pump is another issue. haha

and the replacement will go out also unless the cause was resolved, usually pumps fail because of shit getting sucked up into them, or they run hot and seize up because the pickup tube screen gets blocked, etc.
kind of like resetting the CEL light - it's just going to come back unless you fixed the cause.

touche ![[Wink]](wink.gif) Lucky for me, since I replaced mine it hasn't gone out. Either the cause is very slowly developing or I lucked out.

Anything mechanical can fail. An oil pump is just that, a pump. To say they dont fail is incorrect.
I think what BLIND is trying to get at is that he has probably never seen an oil pump fail on a mustang 5.0 (302) and neither have I.
It is always something else that causes the oil pressure issues and if the oil pumps DO fail you usually find pieces of rocker arm bearings or blocked pick up screens etc as he indicated.

In the case of my failure, it was age. It was an original pump in a '68 302. I pulled it apart and checked it and there wasn't any marring or trash in the pan, pickup, or pump. I measured the rotors and checked it against the specs and they were way out. I replaced it, and put another 5k miles on it before selling the car. Never had any problems after replacing the pump.

Cant argue with that. Ive just never personally pulled apart a 40 year old oil pump but it is mechanical and probably went out of tolerance.

I had a pump lock up on me and twist the drive. The pump was a Melling HV and was less than a year old. I pulled it and took it apart, there was a tiny chunk of metal that looked like a half of a thread stuck between the gears. I cleaned the pump up, put it back in with a new drive and it kept going like a champ for many years, I actually think its still in my buddies 71 Mustang to this day.
