My 87 Regal T has an oil leak somewhere but I haven't been able to find it yet. I have seen oil on the crossover pipe on the passenger side of the car, some oil on the starter, and coming from the hole in the torque converter cover. I original thought it was the passenger side valve cover so I replace them both. The valve covers did "not" fix the leak. Next, I took off the torque converter cover and inspected the rear main seal. I replaced the rear main about 15 years ago and don't think it's leaking from there especially since I some oil on the starter and crossover at the passenger side. I don't see any oil leaking if I drive the car and look under it while the engine is idling. If I park the car and let it sit for a day or two I will see oil on a metal tray I put under the car. After several weeks of sitting, I have cleaned the metal tray, put it back under the car, and looked at it a week or so later and it had new / leaked oil on it even without running the engine. Any suggestions on what to check next?
Thanks, Craig
