At the Carlisle show this past weekend I looked under all the FE cars in the building with the kit manufactures. The cars were only sitting there for 2 days. The floors were painted. Most of the FE had
oil under them. The worst had a 10" puddle. None of the small block cars had a drop under them. With the exception of one vender, they all admitted that FEs are
oil leakers.
One guy claimed they have never had a single complaint or ever saw an
oil leak on any of their FE engines. Their FE was one of the few there with no oil under it. I don't know if I believe his claim, although he seemed genuin and he believed it.
