I bougth the car from elder couple and plan to fix it up and I did. the problem is over heat and compression leak. ok I figure head gasket and I change it. plus new timing belt and water pump. put it together and car run fine for couple block couple times. then I wanted to flush out the dirty oil and water mix in the motor. I put in 1 qt of gunk motoflush and the car start runing rough. and hard to start, it's even making grinding sound something hitting inside. what is the problem can someone help!!!!
