The Haynes manual says to apply RTV sealant to both sides of the oil pump gasket but the BGB doesn't mention it, it just says to apply the gasket.
When I pulled the oil pump off I noticed it has RTV sealant on both sides of the gasket but it also had major oil leaks all around the oil pump area.

To seal or not to seal, that is the question! :)

Seal but don't use too much. Make sure there is no access sealant left on the inside of oil pump. It may get loose and clog up your oil routes.

I try to keep RTV as far as possible from the inner workings of the oil gallery. I use it on the pan and on the corners of the cam covers - only (and I prefer Hondabond on the cam covers and Permatex Ultra Copper on the pan).

Short answer - gasket only; and OEM at that.

+1 for NO RTV on the Toyota gasket

A new, high quality gasket between two parts that are not warped, will not need sealant. I think that using RTV to build up motors is a mistake unless the skin is ultra thin, no chance of creating a "worm" when the parts are torqued, which can literally swim somewhere else......sometime. I like Yamabond 5 applied sparingly. RTV just doesn't have the best consistency for gaskets under pressure. Just my .00002
