So I'm finally piecing together my 4.6L stroker, and thus far it's been a nightmare. I had the pistons in the block when a machinist told me that the hypereutectic style i was using required a top ring gap coefficient of .0065-.008, giving me roughly a .030 gap on the top ring. So I pulled out the pistons, filed down the moly rings to this gap, and then after talking to the piston manufacturers (KB Silvolite) found out that I really need a .0022 ring gap...Question #1) is it OK that the piston ring gap is so high for the top rings? The bottom rings are still at the stock oem recommended gap, and so far I have only filed down and installed half of the top rings. Also, when I was putting the rods/pistons back in, the rod journals got some oil in them under the bearings...at the time I thought nothing of it, but after nightmares of spun bearings and uneven wear, I began to worry, which brings me to question #2) is it ok that there was some motor oil inbetween the bearings and the rod journals? I havn't torqued them yet, so in theory i could go and dry the journals, but that would be my third time tearing that engine apart and putting it back together...Help?
