My buddies coming out Saturday to give me a hand. Taking it apart is easier than putting it back together. About 1.25 hours to get i all apart, I spent 5 hours putting back together due to frequent breaks and forgetting to install the alternator bracket on the driver side behind the intake. Had to pull the injector rail and UIM. Thanks for the offer though.
I'm throwing in a new thermostat just to be safe, I did have a hell of time removing it to install the new gasket which didn't seem to seal as well as the old one. It was tapered down towards the LIM and the one that came off of it was the same thickness all the way through.
I'm not gonna keep arguing about the oil in coolant, I've seen it in the 3100 and given there is a depressurization that occurs as the engine is cooling it could suck oil into the passages in the block. Last time I'm saying it not changing my mind.
When I bought this vehicle I looked at a few Lacrosse Supers and one had white smoke pouring from the passenger side exhaust pipe and a cracked heater core, however it didn't overheat during test drive. The heater core was just turning the windshield orange.
