I agree with the oil inside the UIM coming from the PCV. However, I also had two spots on the LIM where oil was puddling on top of the bolts. One was at #6 cylinder position and the other at #3 position. The LIM gasket was changed with factory gaskets at 57K miles and the engine now has 86K miles. I removed it now to repair the UIM for coolant usage and that'* when I noticed the oil inside the LIM.
Just curious as to where the outside oil was coming from. It wasn't puddling on each LIM bolt, only those two locations.
