Oil pump or new engine????
Ok, now that the pressure is off and I can think logically, I am trying to decide what to do with the bronco. I know that the oil pump is gone - I talked to my mechanic and he said that if the oil pump is gone the whole engine is shot, and should be completely replaced, yet I've read posts here where people have just changed the oil pump out. I have just also discovered that he hates Fords with a passion. Is my engine gone, or will just putting in a new oil pump fix the problem?
Thanks muchly!

Hard to say Joe, How long was it running with no pressure? You could put in a pump and check your compression, but you may likely have done bearing damage if you ran it without pressure. Throw in a pump and try her out before you invest in a whole new engine!

In all honesty fords are a engine that can run on low oil pressure for a while. I agree with "94F150-408" but as long as ya have the oil pan off and the pump out why not pop a few caps, see how bad they are if they are not 100% smoked replace the main and rod bearings. If the pan is filled with more iron then oil, then maybe ya need to talk to ford mech.and not some chevy freak. good luck

oil pressure...what's that? I've had oil pressure problems since I've had my bronco (1 1/2years) I replaced the pump, cleaned out the pickup tube, cleaned out under the valve covers, and still have low pressure. I also took out the dummy oil pressure gauge and put in a mechanical gauge.
I live in TX, and the weather is always HOT. My mechanic buddy suggested using thicker weight oil to boost it. With it being so hot here, it definitely won't freeze...and will take longer to break down.
I use 10W40 and it boosted my "warmed up" pressure to 8psi from 1psi. It runs at about 50psi when cold. I don't have to idle too long after warm up, so my driving pressure is usually about 25psi.
I know I need new bearings, but I don't have the time to do it right now...or for the past year and a half. Basically I'm going to run it until it needs a rebuild...then I'll rebuild it and drive the wifes Chebby...but who wants to do that?!

are we talking 0 oil pressure or just low oil pressure? if it was 0 for more than a few seconds you have probably destroyed the bearings. cam bearings are the first to go then the main and rod next. if you just ran low pressure then you may be ok. low pressure is caused by excessive bearing clearance. if the pan is off i to would change the main and rod bearings,change the oil pump with a high volume pump and put it back together. good luck and hope you can do a cheap and quick job and that it all works out. bearings and an oil pump and pan gasket should cost less than 200.00 dollars.

It had some oil pressure, just not that much. I've got the oil pump (new high volume) & gasket for pan - will check the bearings while I'm there just to see what they look like. The only problem is tearing everything off of the engine in order to get enough clearance to take the pan off. Anyone know what size torx screwdriver I need to take off the intake manifold?
Oh, and I'm going to find myself a different mechanic too! He basically said that the whole engine was trashed without looking at it, and that it wasn't worth rebuilding - I should get a completely new engine or get a new vehicle - anything but a Ford. Hmmmmmmmm, methinks he really doesn't like Fords.

I bought a Bronco for my girlfreind a year ago. When I bought it the pump was bad, no pressure at idle and still almost none at high RPM's. I'm assuming the truck had been driven like this for a long time because the bearings were completley shot.
I pulled the engine and put in a new crank and bearings (cost $120 I think). While I was in there I put in new piston rings (8th cyliner rings were broken), and of course, a new oil pump. Spent only a few hundred, and the thing runs like a charm now (even runs better than my bronco
)
These engines are incredibly tough. I would just replace the pump and crank/bearings if needed. Should get you going for a lot cheaper than a new engine.
Also, in regards to your high pressure pump: I was told when buying my new pump that I should not get the high pressure one cause it would drain my pan too fast at high RPM's. That's what I was told, can someone else vouch for this?
