I have my B230F motor out and all apart except for crankshaft, just don't wanna disturb it as there is just no appreciable wear on anything else that I can measure.. out and apart to decarbonize it and replace rings and conn rod shells and then all the seals, that's basically it. 220k miles. It had lotsa blowby and the rings were all stuck with carbon deposits. Anyway, my buddy says 'gotta put new wrist pins no matter what you see or think, just do it" but I have seen very little about that here and wonder if anybody has opinion from rebuild experience. I don't wanna pull wrist pins out, just don't feel compelled to disturb that part either, to get it cleaned up and back together is goal here...
