Engine Mechanical problem
1989 Jeep Comanche 4 cyl Two Wheel Drive Automatic 121000 miles
I am wondering what this is and how it can be fixed or prevented, people have told me its blow back on the hood not sure what that is. And around the valve cover there is alot of build up and behind the belt as well. Is this coming from the valve cover? How eazy is it to change on if it is?
