Quick question about cams and lifters. my shadetree mechanic understanding is that there are
mechanical flat tappet cams that use solid lifters and require periodic adjustment as well as high zinc oil
hydraulic flat tappet cams that use hydraulic lifters that use oil pressure to keep valves in adjustment? high zinc oil?
hydraulic roller cams that use roller lifters
Would the 93 4.3 tbi have the hydro flat tappet w/ hydraulic lifters? If so, do the valves need to be adjusted periodically?
