I have a oliver 660 My brother thought it be good idea to put in 5w-30 in last winter .
thinnest oil I ever put in was 10w-30 . what it did is now I have oil everywhere
leaking from valve cover and head gasket. Have you ever heard of 5w-30 doing this to the gaskets ?
Im only guessing the 5w-30 might be more prone to do this .
