I think it might be going again, just had it done about 30k ago. I see a small pool of what looks to be coolant on the back of the engine pooling up in the molding on top. I don't have any money left in the budget to get it fixed. It is common to have it go that quick? Suggestions?
the UIM on the Ei is just a paper gasket between the blower and the LIM so not thinking it'* that. your LIMs sound like the culprit. when you replaced them did you use the fel- pro perma seals or the nice thick GM updated ones? i have seen the perma seal ones and am not really impressed with them.
Where exactly is it pooling up? Passenger side, drivers side, front, back. On the drivers side it'* likely the throttle body gasket. Passenger side, it'* likely the elbow. When the LIM gaskets fails, it will not leak to the outside. Instead it seeps in to the lifter valley.
