So I recently purchased a 1990 Mustang GT, so far it doesn't leak anything beside a little power steering fluid (or radiator fluid I'm not sure). Anyways it leaks a little bit of oil from where the oil pan meets the bellhousing. The weird part is that it only leaks when the engine is cold, It can go 2+ hours after the engine is off before it starts leaking and seems like it then only leaks for a few hours before stopping (maybe something draining?). Thanks in advance.
Thats a fair amount of oil, so I understand, the leak comes from the bell housing when you turn off the engine, does not leak when engine is running. And it's not the rear main, that would leak when the engine is running.
Ok, first lets establish that it is motor oil and not trans fluid, place a pan under the area the oil comes from and capture a sample then see if it is oil or trans fluid.
I suspect its going to be a rear main I just cannot figuare why the leak acts like it does, can you take a mechanics mirror and look behind your intake for a leak where the lower intake meets the block, also check the valve covers back by the firewall.
You can get that little mirror on a stick at any auto parts store
It's definitely motor oil, it's black not red. Looked up at the leak and you can see it pooling up at the top of the oil pan and seeping down the front face of the bellhousing. I will check the intake and back of block. Hopefully it's not the rear main but I guess it's not the end of the world if it is.
