I believe i have a broken rod in my 03 deville dts. My engine stopped without any significant notice. Went to accelerate during a turn and noticed no power steering and no throttle response...the engine had quit. I forced the steering around the corner and coasted half a mile down a hill and off onto a side street. Put it in park and tried to start it up...no luck. One click and the lights would all go out. Seemed like a dead battery so I put a new one in. Same thing again. I figured it was just because the new battery wasnt fully charged. Got it towed home and charged both batteries. Same thing again... wouldn't start and lights would go out. I considered it was possibly a safety mechanism for an overload and tried to turn the crank with a breaker bar. Well it seemed siezed!!!! Tried to rotate it backwards slightly and it went with normal force. Then it would turn forwards right up to the same exact point and felt like it was hitting something. It wasnt leaking oil anywhere, the oil still looked black, and all the plugs but one looked good. The # 7 or 8 spark plug appears to have been hit!!
So here we are. I am afraid to pay a local shop $2100 to install a $900 80,000mi junk yard engine and then expect to have a reasonably reliable car. I dont think its worth risking $3000 and if there is any problem I am screwed and I cannot take that kind of chance. I have found Davis and Cadillac Doctor and they will install a rebuilt with the 1yr warranty for $3000 in Ohio. That sounds like something I could consider if they are legit. I havent seen too much talk on here regarding them.
Has anyone dealt with them? Does anyone have any other suggestions.
