1999 Chevy Camaro Help me

First off, check your battery. But if you had water in the oil, I pretty sure you blew the head gaskets or possibly cracked/warped a head. If you jump the car and it sounds like #&*@, you need to have the heads machined at a shop and replace the head gaskets. Then pray that you didnt do anymore internal damage. If you dont run it anymore, you should be fine once the heads are machined and gaskets are redone. Best of luck. :)
