Good Afternoon,
wondering if anybody can give me advise on getting my s2k back on the road. I recently changed the spark plugs and left one of them loose. it popped out and burned the coil as I was driving. The car turned off and I was not able to revive it again. I changed the coil and spark plug, which I had to retread the spark plug hole with a re-tread kit from auto zone.
some folks are saying that I need to open up the engine case to see if there is any particles in the engine and have it cleaned and check the damage. my question is this, is it safer to replace my engine or have some shop go in and inspect the damage and fix, which I assume would be a grip of money. Any advise would help..

Bummer to hear this happened, always sucks something extra special when damage is self inflicted .

Replacing the engine is obviously the worst case/last thing on the list. I dont see any evidence that you are there yet. So you re threaded the damaged plug and now you can get the plug to torque spec yes? and the new coil pack has been replaced I understand. If this was the only damage then the engine should start. Even with potential engine damage to that cylinder. So have you started it? If you have not, before you do, after chasing the threads, I would run a cam/scope down that cylinder to see what kind of thread debris there is. If you see some, I would hand crank the engine to get that piston to top dead center and take a wet rag, even clay or chewing gum at the end of a rod (making sure you dont lose that in the cylinder)and try blotting any shavings out from top the piston. Ive never done it, but it should feasibly work. Depending on how that went, id consider pulling the fuel pump fuse and turning the engine over without the plug in that hole and have the compression blow the debris out. You can stick a wet rag part the way down the hole wile a buddy turns the engine over, and hopefully most of the debris that may be there sticks to the rag rather then just blow out and fall back in. Then I would change the oil and filter and put it back together and run the car and forget about it if it sounds/runs good. A few soft aluminum shavings should really do very little to nothing in regard to engine damage/scoring cylinders. One thing that would suck/could happen, is you cooked that cylinder from sucking in oxygen past the spark plug wile driving, but we dont know if that kind of damage happened or not. There are symptoms of this, but you wont really know until you start driving the car.
