timing gear breaks on 420 sel
Hi I am brand new to the forum. My name is Lewis in Nor Cal, I have owned a 1990 420 sel for 3400 miles now. IT has 200120 miles on it, 1 owner and is in perfect shape. Just did new rotors all around belts and oil change. I went to start it on 09/15 and I heard a big bang. opened the hood and found something had made a 2/3" hole in the drivers side vale cover right on top of the timming chain. the motor did not start during this time and has not since. I am going to do a compression check to see if any valves hit pistons etc.
