Take a spotless cleaned piece of glass and lay it flat on the table next to your very expensive disassembled engine parts for the same amount of time the parts sat exposed…. There's a good reason why elite engine builders use a white clean room that's dust free for engine assembly and wear rubber gloves when handling parts to not contaminant surfaces with acidic finger oils. Like cams and bearing surfaces, block deck and cylinder bores, head deck and gasket…. Yeah it'll work your way but for how long??? TRC 1000+WHP 4G63 EVO HAS BEEN TOGETHER OVER 8 YRS AT THAT POWER LEVEL, CONSTANTLY PUNISHED AND IS GOOD AS NEW! HOW LONG WILL YOURS LIVE??? USING BACKWOODS BOBBY ASSEMBLY PRACTICES?
