i have a 560SEL motor with 140k. seems to run strong, immediate start up, no smoke. since it is out of the car i am thinking i should change the mains, rods, rings and oil pump. an MB mechanic friend of mine disagrees and says all i should do is chain, tensioner, rails and POSSIBLY head gaskets. one of this thoughts is that he would rather keep the car factory assembled because of better build quality.

in my ignorant mind, i am thinking of polishing the crank, honing the walls, and throwing in some std. bearing and rings (providing that the journals and cylinders are not out of whack

i just don't want to pull the engine again; so if i have to bite the bullet and antie up, then allright
