2004 Grand Prix - HELP ENGINE KNOCKING

[mzfire]

Hello - What the hell is wrong with my car?

I hope someone can help me I have a 2004 GP I have had the car since 2006. Just hit 200k now the engine is knocking as if it is not getting oil and it is running hot.

My mechanic check out everything can't figure out why. He recently put new value and intake gaskets on it because they were leaking. He said when he started the car after he installed the gaskets it was idling low so he adjusted the hormonic balancer. The car ran great that evening I picked it up. She felt almost new!!

The next day when I got to work the low oil pressure light came on and there was a little knock so I went about a mile down the road to Advance Auto. We checked the oil and it looked like it was 2 quarts low so we added 2 quarts. Drove for about 15miles and got off the expressway and it was still knocking but louder the temperature gauge started moving towards hot and the low oil pression light kept screaming, drove to the nearest oil place and had them check the oil he said I was 2 quarts over and he heard the loud noise also.

The car was running fine until we replaced the gaskets. Fine as in I had to add anti freeze often and by the time I got my regular oil change I was about a quart low. So the leaks were heavy. I probably could have not got them fixed and kept adding antifreeze and oil.

I don't want to get a new car yet. Actually I was planning on keeping the car when I do get a new car because I love this car!
