Had a bad piston, 1996 4runner 3.4, 280k miles
Heads look good. Engine ran well, no smoke but a ring got stuck and scuffed the cylinder. Valves were on target (I adjusted 2 one size in trying to fixed the engine noise that turned out to be the bad piston).
The idler bracket for the main belts is bad (I tried to regrease and messed up the bearing seals).
Let me know what you want, offer?
Cheers
Mike
