Hello Everyone,

So my 2004 grand prix gtp had a leaky oil pan gasket, intake gasket, and timing cover gasket replaced after the shop I go to recommended doing this before the leaks got any worse. After charging me about 2K to replace all the gaskets, I got about 3 hours of driving time before the motor quit. I had it towed back to the shop and now they tell me crankshaft is scored so the engine is basically done. Things were working fine before having the gaskets replaced, it was more preventative maintenance. The shop feels really bad but hasn't done anything else. So now I'm out 2K on the repair bill which unfortunately I paid right away and now the car needs a motor.

They have no idea what caused the scoring but I'm going to talk to the mechanic on Monday about where to go from here.

My question is, do you think they messed up my engine or is this a coincidence? It has 315,000KM (195731 miles) but was working fine before the gasket replacement. I've always been diligent about regular maintenance and oil changes.

ANY advice is very appreciated as I'm going to have to figure something out with the shop on Monday!
