Just putting my oil pan back together, and realized I dont know what kind of sealant to use, if any. I am putting the upper half back together with the lower half after doing the turbo drain tube job-o'-joy.

FSM makes no mention of any sealant for the upper to lower oil pan. I was going to use some Permatex High-Tack non-hardnening just to keep in it place which I screw it in.

Any suggestions?
