Re: Engine cleaning after terdown, before final assembly?
Cleanliest is utmost importance in any build.
After my motor is back from the machine shop, after mill or bore work but before cam bearing are installed and with all cam oil galleys plugs out and tapped for screw in plugs, I was my motor with solvent to remove the remaining oil . Once that is done I wash the motor entirely with SuperClean , the purple stuff or something like that. I clean out all oil passages with a rifle cleaning tool.
I hot water clean manually , paying close attention to the new bored holes , water jackets and passages.
Once satisfied you can eat off this motor, I spray cly bores with light oil, WD40 will work.
I use lint free rags to wipe down and blow out everything.
I install my cam bearings and I now am sure there is no metal shavings in the oil galley behind the cam bearings.
Some guys go to the extreame of painting the lifter valley area with hi temp GE Glyotal paint to speed oil in valley area back into the oil pan.
Everything that goes into the motor , is inspected , included the oil pump.
Hope this helps
