Hello,

I've begun working on my upper intake manifold, thinking I have
developed some problems with the EGR plenum. Well, after removing it
and not seeing the immediate signs of this failure, I believe I have a
different problem.

Please see these pics:

You can barely see, but in the upper left portion of the lower intake
manifold, I have enough oil pooled to cover one of the bolts that hold
the LIM on.

I will be replacing the UIM and PCV valve, as well as the gasket/seal
and properly torquing the bolts.

But where do you think this oil came from? Do I have another leaky
gasket? Should I remove and degrease the LIM, or just soak up the oil
and clean the gasket/seal part of the LIM?

Thanks for any input!

Tom
