I almost have all the parts back from the machine shop for my ZC. Once thats done I can put it back together. I do have some questions, and will probably ask more after that. I want to make sure I put everything together just fine. Whats been done so far: parts: remanufactured crank (old one was out of spec) new rods new pistons new rings new gaskets all around new bearings (will get from machine shop, oem) machine shop work: block line bore w/crank rotating assembly balance (what I'm still waiting to be finished) block has been notched (by me actually) resurfaced stock flywheel I have access to just about any measuring tool available. I have checked the cylinder wall tolerances, and they are good. Please add any comments or tell me if I have done something wrong, this is somewhat of a learning experience for me. Questions: 1. I notched the block, there is iron dust everywhere in the block, whats the best way to remove it, powerwash and clean the cylinders with oil or wd40? 2. Is there any special bearing grease I should use? 3. I get differing answers on this. When I check the oil clearence for the bearings, should I check them dry, without any grease? 4. This may be a question for the machine shop. Once the parts are balanced, do they have to be clocked certian ways to each other?
