Lower oil dipstick gasket part number?

[jhax]

Just as the title states, what is the umber for the gasket that goes in between the base of the dip stick and the hole in the block.

Thanks,
Justin

Consider getting an "O"-ring from the local hardware. You can size a pretty good fit for sealing purposes. Then a little RTV sealant before inserting it into position.
