LIM what do you think

[Gilmour]

Hello,

Today I did the LIM & UIM for my 2001 Lesabre (~100k miles), there were some minor sign of coolant leak near the throttle body, so I did both the UIM & LIM, when I took out the upper intake, I found oil in lower intake, my guess is the PCV, what do you think?

Thanks.

Sir,

Are you satisfied that it is oil and not anitfreeze??

well, i am glad for 2 things:
1) Didn't find antifreeze there.
2) I changed the bypass elbow - from what i saw (cracks) it was a matter of time till these elbows were history and find my self stuck in the middle of the road.

But should be oil in there? and that much... i barely saw the top of the bolt there.

Thanks.

The 2 inside corner lim bolts should be sealed as oil can migrate up those bolts.

already assembled the lower and upper, and there was no seal for the inner bolts, so it's too late now for adding seals

assuming it the first time this manifold was taken apart, what do you think this oil's source? and is it normal?

Thanks.
