for the past 2 months not i have been complaining about how my truck has no power,gets bad gas mileage, idles like crap etc. Well I finally found my problem. To start, the rotor was pointing 180 degrees off on TDC instead of at # 1 plug. Then i took off the valve covers and two rocker arms were just lieing there in the head bay. WTF! Im a beginner (17 years old with no help from parents) so im proud. After i fixed it and bolted the valve covers back on i broke one of the covers at the hole. Well i welded the piece back with the JB weld stuff and there are no more leaks. Now it runs like a champ. Its never run like this before. the only thing wrong is i got oil spilled all over a header so it smokes like a frieght train. anyone know how get the oil off? what chemicals can i use?
