My car has no oil pressure and they said I need a pump and main and rod bearings. Can I just replace the pump? Or can you tell the bearings are shot by just hearing it?
because of the fact's a extra cutting-edge gm engine, i might guess that's a collapsed piston. the skirt of a collapsed piston will make a knocking sound because of the fact that is hitting the cylinder wall. if the noise is loudest while the engine is first began in spite of the undeniable fact that it each so often is going away, i may be almost particular that that's a piston.
It will probably cost more to repair the T-bird than it is worth. I own a 2001, Jeep Grand Cherokee Laredo and recently had both transmission bearings replaced. It cost me $886; had a CO2 sensor replaced and it cost me $330. Auto repairs are extremely expensive. I agree with the first answer.
That is serious work you're talking about, if you do that you might as well have the entire engine rebuilt. And if you've run the engine at all without any oil pressure there's probably other damage already done to the engine. Overall you're better getting a rebuilt engine or having a junk yard engine and having it rebuilt. That's only if you really like the car. Otherwise it might be time to look for something newer. There's nothing wrong with putting a lot of money into an old car if you really like the car. If you have a connection with the car it's definitely worth it. But if it's just a means of transportation to you, it makes more sense to just get something newer. A bad rod bearing usually is accompanied with type of clicking or clattering sound in correlation to engine speed. You'll have to go off the word of your mechanic. Failure of rod bearings eventually leads to the destruction of the engine sometimes immediate and catastrophic if not taken care of. Good luck.
Bad rod bearings can be heard and replacing the oil pump is recommended but not required. But before doing the work, it might be wise to price a salvage yard engine. This is because the rings, valves and other parts will need to be done next. True it will not have new bearings, but if you don't plan on owning the car for more then a year or two, it might be the wiser move. If you plan on owning the car for sometime, just get the engine rebuilt completely. Other wise it will just be one engine repair after another.
