Hi Guys,
I noticed I was getting a leak from this area the other day, so I picked up a new O Ring for the sending unit, cleaned the mounting surface, lubed the new O ring and installed, only to find that I have only slowed the leak.

It looks like the oil is not leaking from the seal against the pan, but from around the area where the wire plugs in.

If you look (obviously the sender is turned sideways) where the 'lip' is (around 9 or 10 o clock in the pic) that is 6 o clock when the sender is in the pan. Every time I open the hood, theres always a little oil right there on that lip.

The other thing I did notice is that there is an O-Ring around that plug for the wiring. Does oil run against the pigtail too?
Anyone experience this before?

Thanks
