What is this part under the intake manifold? Near the oil filter and dipstick? I can tell it has a bad seal and oil is slow leaking and I don't know what part to ask for. If anyone could tell me, that would be great

 

Did you ever find what was leaking? I am having the same problem. What are some possible causes?

 

Its where the oil filler tube meets the plate. There is a gasket there...

 

Thanks for your help! Are you saying that it’s this gasket? By the dipstick? There is also oil that is higher than that gasket like on top of the oil fill assembly. Is it possible for oil to be leaking from that gasket and moving its way up? There is oil leaking all the way down onto the crossmember and pooling up.

 

It tends to.leak from the gasket and then the wash from the fans blows it up there. It could also be from around the oil filter or the pressure switch also..

Best thing to do is clean it up and then watch it closely for a few days to see where its leaking.first.
