You mentioned that the MIL comes on. Are you able to scan for the fault code(s) that the MIL indicates are stored in the computer? That might give you a clue as to where the problem is coming from. Let us know.

Ouch, are you sure about the "white" smoke, that could be bad. Give it a sniff, se if you can pick up any coolant stink in the exhaust. If you think so, do you have a reputable repair shop nearby that could do a leakdown test? The head gasket may be bad. 3.8 engine is a known troublemaker, ever replaced any motor mounts? Why did you replace the ccrm? Just because? Don't waste money replacing pieces if there's no indication they're bad.
