Oil Pump Options

[CG-914]

I know that oil pumps are the bases for discussion, but:

I do have a type for and a type 1 pump,
But I like the Idea of having a type 4 pump, that lines up and is made out of aluminum,
like this one.

It has the same expansion rates like the block.
Has anyone used it?
What is the QUALITY?

Thanks Mark, great info. and explanation of the purpose of the circular groove.
I assume the parts stores know what "Threebond and "RTV" are(?). I assume I will have to get both new gaskets, although the thick gasket between the pump and the engine case appears to be working and I may choose not to disturb it. Do you know if this plate comes with a gasket?
I hope I can pull the pump cover tomorrow without removing the engine again as described above. I will order the steel cover plate as you suggest and plug it and lap it flat.

Threebond 1104, Yamabond, Hondabond is all the same stuff, ebay or go to a Yamaha dealer.

RTV Black well some guys give me shit for that and tell me a different product is superior...then get all pissy when I point out their superior sealant is also RTV based.
RTV has a bad rep because peeps use it wrong and/or in the wrong places.

Other sealants also work, but on the pump cover if you gob it on and block the groove failure will happen, just a matter of time.

Cover gasket is often separate but only about $1.
