My rule is: if a steel bolt threads into aluminum, it gets a coating of

Therefore oil pan bolts get never-seize. 

Of course I worked on these since they were everyday drivers and oil pans
rusted through from the outside here in salt weather. So never-seize helped
keep the fasteners from seizing in the aluminum.

Remember, the never-seize pamphlet showed using it to keep the Corvair
aluminum bellhousing from corroding against the iron differential.

Hi Bryan,

I'm not too sure about using anti-seize on the pan bolts.  First, probably
not needed.  I don't remember ever having one rust into place <GRIN>.
Second, the lube effect of the anti-sneeze (an lclc word) might lead to an
over tighten (over-torque?) situation.

I DO suggest washers to help spread out the forces on the pan at the holes.

Later, JR
