Hello everyone,
My stock 89 Turbo 2.5 van developed a pretty bad oil leak on the passenger's side of the engine. It seems to be below the midway point of the cylinders on the block.... I'm thinking this is either a bad oil pan gasket (Which I replaced last in 2006)
or my intermediate shaft is leaking... Which is more likely? The engine has 226,000 miles on it. It is making this horrible noise of a bad bearing, but only in the very cold weather. But I think that is transmission related (520)
What is the best way to tell where I'm leaking without just replacing the oil pan gasket?
