yeah piston rings.
big end and mains bearings.
well keep in mind u will (99% sure) have bent valves.
so there is more cost, and just hope they rnt bent enough to damage the head.
have seen valves bent over sideways, and smashed thru the head before (on a mitsy motor but)
now u could just do the head up, but if the motor is old prob best to to the whole things, although if the mains r alrite then u wont have to take the motor out.
the rings wear out pretty quick on them, especially the oil rings, think it's due to contamination from the egr and crank vent setup they have, and very small oil drain galleries from the topend to the sump.
