FC oil pan remove & reinstall question

[Rotary Related]

Make sure to clean the flange of the oil pan and the bottom of the engine really, really, really, really, really good before reassembly. Or the rtv/silicon will not do it's job. You may or may not use a gasket. That's up to you. Both ways work fine.

You'll know its clean enough if your willing to put your mouth on it. It wouldn't hurt to just clean the oil pan up inside and out. Then you could even repaint it if you like while it's out.

I would not recommend this for those who don't know how to paint something that was oil immersed.
I would NOT recommend painting the inside of the oil pan especially.
If the paint on the inside of the oil pan happens to flake off (and most likely it will), I shudder that thought of all that paint flakes in the oiling system!

Most people don't know that most metals are porous.
Oil can actually soak into most metals - i.e. steel and aluminum.
This is why the oil pan is a ROYAL PITA to seal.
Most RTVs and most sealants cannot seal against metal that has oil in it.

Why would anyone want to paint the inside of an oil pan? I gave about a millisecond of thought to painting the outside surfaces while it's out, but one look at it and I concluded it looks good enough as-is.
