I have a 1999 Grand Am 3.2 engine 140,000 miles. I drove the car home (It was driving perfect) came out the next morning after a cold night and the car would not do anything. It was completly dead. I had my grand am towed to a local repair shop. The mechanic informed me that the cam shaft had broken and there are metal flakes in the oil. He said I would need a new engine. Due to the cost of the repairs I had it towed home and it has been sitting for the last year. I recently had the car towed to a different repair shop to have the engine rebuilt which would cost $2000. Upon looking at the engine this mechanic says that it is the crank shaft that broke and if I had the engine rebuilt I would just continue to have problems. He suggested getting a engine from a salvage yard and having it put in. Can the crank shaft be repaired? I am a young mother of 3 and don't know if it is worth $1500 to have a salvaged motor put in that has 80,000 miles on it already. Or if I should just get a different car. Thank you for your help!
If either the crank or the cam were broken there is a good chance the block is damaged and non repairable, if you dont want a car payment go ahead with the repair, I would suggest a gm reman engine that has a good warranty over the salvage yard engine, the slavage yad engine may be damaged or have leaks and end up costing more than the reman would have, if you decide to keep the car the reman is the way to go
