Leave the motor upside down for a day, or longer, to.make sure the silicon is.dry. Make sure you clean tye hell out of the new pan too. I put extra paint and then bedliner on mine. While the motor is out I would.also.spend the 60 bucks and overhaul the oil cooler. You'll probably wind up taking it off anyway.
Id strongly urge you to get new dipstick parts. Tube, nut, adapter and orings. I glued mine in. No orings. Also Connor, a seal kit can be had for under 100 bucks that will reseal the front cover, water pump, and hpop. It'll also get you the rubber where the oiltube seals against the front cover.
As stated, clean the bejesus out of it. Let the oil drain as long as you can.
