I have 402 stocker engine that seems to have a lot of blow by. Having build this engine several years ago . it is a 454 block sleeved back to a 4.185 bore. Cp piston race rings honed the first time sv 10 diamond stone sealed up made reasonable power. Hauled it back to sd where it sat for 3years in the shop. Was going to sell it so put it on engine stand and ran it smoked out of the valve covers a bunch. So I took it apart had it honed. Reassembled it new with race rings ,put it on the engine run stand same thing. Took apart once agin. Took it to victory engine had it honed once more . New pistons and rings etc. I look the engine over upped the oil the ring thing still smokes out the valve covers. Not a little a lot. Any ideas?
