Engine Mechanical problem
2003 Chevy Malibu 6 cyl Two Wheel Drive Automatic 104000 miles
I have just replaced the lower intake manifold gasket. In order to replace the gasket I had to pull the rocker arms and pushrods out. Once I replaced the gasket, I reinstalled the rocker arms and pushrods and put all components back together. Upon startup, the valves are making a lot of noise and the engine is idling very rough. My brother is an ASE mechanic and told me that this model has hydraulic lifters and the motor needs about 20 minutes running to pump the lifters back up. I did that but I'm still experiencing a rough idle and valve noise. Any suggestions?
