Hi! I have a 1995 base bird w/3.4L and auto trans. It leaks oil. Oil comes from somewhere in between engine and tranny, leaks into flywheel cover and then leaves puddle when car is parked as the oil comes out the lil hole in the flywheel cover. It splashes back enough to coat the tranny pan. I need to add 1 qt of oil every 125-150 miles of driving. It was leaking from the day I bought the car. I brought it to my father's repair shop and he showed me that the main seal was previously done evidenced by the end of oil pain having black seal around it but claimed it was still leaking out of rear main seal. He replaced the seal, started the car up and relifted it and saw it still leaking. Told me he could not see exactly where the leak is coming from, claimed the only true way would to take the engine out due to the manner of how it sits tucked in. The guy has been doing this work for more than 50 yrs so I ASSUME he looked in all the places that he could see. It's a damn shame because the car has under 100,000 miles, about 67000 and is pretty mint other than the leak. After that, I sent the car to 9 big shops and none can find where is this leak coming from. Engine is clean on top, it does not smoke and there is no loss of coolant. Anyway, 1qt every 125-50 miles....is that considered a minor leak or a severe leak? Another person told me if the leak can not be determined, cannot be found, that these engines are prone to leaks of the LIM (I suspect passenger side but not sure). and that the best thing I can do for it is get a small block 350 and swap it out. Most advice I have gotten was that the car is not worth more than a few hundred dollars and an engine overhaul ( rebuild every single seal possible where oil can leak) will cost several thousands of dollars and that it is probably best to junk the car and move on to something else. In any case, leaking that much oil is severe or minor?
