Oil temp sender leaking (S6 and 4kq)

[MXHOWES at aol.com]

On the 4KQ just unscrew the sender, some oil will come out and a spring & 
ball. Have a clean dish under it. You won't loose any prime. On my 4KQ I was 
convinced that it was the sender leaking but it wasn't. Take a real close look 
before you buy a new part. I still haven't found where the oil is coming from, 
maybe the valve cover, but it ends up dripping off the sender unit.
