Taking on coolant internally?
My 95 SLE last year had the LIM gasket replaced with the updated one, the UIM was found to be sleeved and in very good working order. We did this because the car had sat for a good part of it'* life and even the rear main needed to be done. The only thing we never got to do was the head gasket cause at the time we did all this it wasn't known to be leaking. There was a small oil leak on the outside and my mechanic just told me to keep an eye on it. Recently I know that colder temps may bring the coolant tank to lower but I refilled it, and now it seems like it lowered again. Granted today it'* 34 out here with massive high speed winds, it still seems low to me. I don't see massive steam coming out of the exhaust, and a quick look at the oil on the stick it looked ok, but I have to check again. What other things should I look for to determine if antifreeze is leaking into the motor? Is there any other ways to check for a leak? I looked under the car and around and don't see any leaking, but in the time it'* taken it wouldn't be something really fast, it maybe went down about 2-3 inches in the tank, it'* down near the narrow part now (overflow tank)...you guys tell me....

Mike,
A few things come to mind. I would check for leaks at the UIM / LIM mating surface. You mentioned that the the UIM was sleeved. I wonder what size EGR stove pipe is on it. Is it .5 in ? Also how many miles on the car and how many have you put on it since the LIM gasket repair ? There could be some warpage on the UIM and it'* leaking internally. The fact that the UIM was not replaced the last time kind of points me in that direction.
Another possibility would be that the LIM bolts have worked loose, but thats a long shot. Maybe check them for proper torque.

UIM was a sleeved aftermarket one, found to be in perfect shape when checked when we did the revised LIM gaskets. I am seeing some seepage around the LIM I believe, may be oil. Does not seem to be anti-freeze.

Its leaking somewhere... If its not on the ground you need to figure out where it going....
