i never said i was an expert, just trying to help.

the threads I posted deal with this same issue.

And from what Ive seen on here if hes missing oil and hes got the 3400 then its most likey the LIM. There have been so many documented cases of the LIM leak. the sludgey coolant is one of the first signs. also check to see if there is any white residue under the coolant cap of the resovior and or radiator.

If you wait too long you will start to see your engine temp rising and your low coolant light will come on. You shoudl look around the engine and see if you can see any leaks. if you can locate where the LIM meets the block you will see the gasket and possibly some evidence of a leak. I wish I oculd find the old thread with all the pics. I will look for it.
