When I changed the timing cover seal on my 235 (1957 era) there was what I would call an "oil-slinger" type of cup on the crankshaft end where it goes thru the seal to the pulley. Obviously it helps keep excess oil away from the seal. When I did my other 235 (1954)this oil slinger was not there. I made some inquiries and was told that it wasn't really neeeded so I put it back together as-is. My first 235 has stayed bone dry in that area whereas the second (without the part) still leaks oil. In fact there has been a history of oil leaking from that area and I am wondering if I should try to find this piece and install it. Being a loose fit I don't think it actuallys keeps any oil from lubing the seal but I may be wrong.
