A puzzle with only piece of mind at the end.
While fitting the old sump guard (which is another story in itself) I noticed silicone globs all round the sump. Im just wondering what work may of been done on this engine. Its not clean enough to have been fully stripped or at least recently but it runs well with no crankcase fumes at all which is pretty good for 220k plus or minus any jap import adjustment.
Ive no interest in taking the sump off just to find out
