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. | | |

The Chev parts books are not very clear but it looks like the slinger started in 1956. The slinger is held tight between the gear and the balancer. It is the same slinger as small blocks use. If you need one I have several.
