Possibly bad LIM gasket on 04 GTP

Guys...Let me know what you think. I've been so swamped with work lately and barely have any time to ever work on my car and when I do have free time, I'm busy working on my 03 Envoy. My GTP has 188k on it and it had sat idle for almost the last 6-7 months. I just replaced my catalytic converter on Saturday and now was hoping to get to drive it around some and give a break to the Envoy. I took it for a 10 minute ride and when I came back home, I could hear the coolant bubbling (I assume in the overflow tank). After it cooled, I checked the radiator to find it low. I've had a problem for quite awhile of coolant "disappearing". I checked the oil and it appeared a little creamy and not quite the consistency of normal oil. It wasn't to the point of being white.

What do you guys think? Possibly bad LIM Gasket? I thought I heard on here that the 04's shouldn't have that problem. I did have problems in the past after I first bought the car that the coolant turned to gunk and I think it pretty much plugged up the system. The engine overheated and I ended up blowing out one of the bypass valves and ever since then I have always been having coolant troubles.

If it is the LIM gasket, how big (long) of a job would it be? I can't bear to tell the misses that I have a new issue with the GTP. She's ready to set it ablaze.

Thanks
 


its the na engines that the upper intake fails and mixes coolant to oil. its rare on a sc engine.

your issue sounds like a head gasket maybe. id start with a compression test first.
