im having problems removing new pistons/ rings from the cylinders by the top, no ring ridge.
the old ones were hard, any suggestions?
the major problem is this:
i have valves hitting pistons, now i've heard it before, timing, that is why im posting cos its not a timing issue. you regress, i see, let me explain. crank is tdc, cam is tdc, and injection is on (#1 firing). pistons are new, mahle. head is new, all parts are new. cyl head gasket is 3 hole and the right one. timing belt is new, tension is normal.
here's the 1 problem, the reason i found this is my dad did the bottom end and rods 2/3/4 were backwards, so as above they must come out. let me explain this, cyl 1 hit the most, valve is gone. cyl 3 hit and valve i didnt check (im just going to get all new as it is). cyls 2 and 4 brushed. all were intake hits/brushes. why would this happen if as i said my crank and cam timing are on, and cyl 1 rod was not backwards, and cyl 3 hit substantially? 
i'm stumped, any feedback, and yes i know how to time a diesel. crank was at correct tdc mark, cam was tdc. has any one heard of this? rebuilt motor has less than 50 miles on it, and was never reved up much, valve springs are new and ok.

well i'll have to measure 1 and 3 piston heights and see what i get, gosh -busted.
