over heated once then i drove on it more tried blue-devil and it didnto help and it needs new head gaskets which cost 2500 with shop labor to get the car running again it would be faster and easier and better idea to put a 50k crate motor in from japan for 1200 so i sold the car for $400 but i bought it for $900 so no biggy
