"2000+ common problems
The main problems are as follows:
1) Rear Main Seals on both 3800 Series II Engines.
2) RH Valve Cover Gaskets leaks (the one closest to the firewall).
3) Upper Intake leaks coolant at Throttle Body Assembly (some internally & some externally)."
I wonder HOW frequently they happen. Is there a way to check these things before you buy the car without taking the car apart? Im not to good with fixing anything on cars. Computers.... yes. Cars..... no. :(
