It sounds like a clogged oil tube to me too. But as someone said, that requires pulling down the oil pan, a big job. It's a stupid little tube about four inches long and it is threaded into the rear main bearing cap. It doesn't look important at all! However. Make sure there's a gasket between the flywheel housing and the engine block. I know it sounds weird to have a gasket between these two parts but there's a reason for it. It seals the back of the camshaft. If the engine or transmission was recently removed by the previous owner, he may have left the gasket out, not realizing the importance of it.
