9U,some things you need to understand, from what I get from your post. The carbon ring is very good, that is correct. It means that your rings are not letting any oil past them. Now getting to your major problem the constant blowing gaskets. Take the old gasket and look where it was blown, you may have more than one spot. Then look at the liner tops in those areas for any signs of the carbon washed off the liners and pistins. Then polish the tops of the liners and block clean. Each liner must be clamped down with an H bar to 60Lb Ft. and the height of it's flange above the block measured with a dial indicator in 4 places around the flange. Projection should be 0.004" to 0.008" with each liner's measurement with in 0.002". You most likely have a low liner, you can get the piston and rods out the side but if you take the pan off!!! The oil pump and ballancer comes with it!!!! The ballancer weights must be timed upon assembley. ""any piston on TDC and the weights at the bottom."" Use one of the 1/2" mounting bolts to lock weights untill the gears are engaged, then be sure to take it out. When you get it apart new liners might not do it, liner seats might need cutting and shimming but will get into that then. Later Bob
