I have a 1937/38 Ruby with a pressed steel tappet cover. This does not have any breather holes. I am having a problem with oil being splashed out of the filler cap. It is difficult to believe that the splashing in the sump could send oil all the way up to the filler cap. Perhaps blow-by is wanting to exit through the filler cap and carrying oil up there.
Does anyone have experience to help confirm that blow-by is causing the oil spilling? Also, should there be some other form of breather for the blow-by On this engine?
