Engine Mechanical problem
1998 Oldsmobile Silhouette 6 cyl Front Wheel Drive Automatic 100000 miles
I am a mechanic. I have just put intake gaskets on an Oldsmobile 3.4L. Have done several of these in the past. Now I have no compression, unless I loosen the rockers. The push-rods are in the proper location. There was considerable sludge in the engine. I washed this down with solvent before reassembly. Do I have a lifter issue? If so, why?
