Question about 1999 Jeep Grand Cherokee
4 ltr/straight 6; engine overheated resulting in cylinders #3, #4 compression at 30 (other cylinders @150); certain that head gasket needs replacing, but also hear a noise that sounds like rod bearing knocking. Would the knocking be consistent w/overheated engine or could this possibly be a valve?
You probably messed up a rod or caused piston damage your going to need more than a head gasket usauly when you over heat a car you causing the pistonts to expand more then they need to causing scouring and exsisive piston ware by the sound of it and the year your better off replacing the whole motor or completely rebuilding the old one wich will cost more then a use motor! good luck!
