Your doing a great job Allibaba,if it were me Jason I would do the moroso aluminum weld in breathers w/ integrated baffles and filter assemblies.I did notice some blow by but figured it would go away as the rings began to seat,I guess that is not the case?Or is it just the usual oil vapor and residue.Run it by the engine builder and ask him if he is alarmed by the amount of smoke maybe.LMK if I can help.
