Just wondering peoples thoughts on using loctite 515, 518 or a similar anaerobic product in place of an oil pump gasket? Normally I'd say gasket, but curious as to what others think.

Most oil pumps that use a gasket are engineered to use a specific thickness gasket. Too assemble one without the gasket will likely destroy the pump and everything down stream. Getting sealer inside the pump cant be a good thing.
Or are you talking about the mounting flange?
Yeah, most every oil pump I have seen uses a very thin, almost see through, paper gasket between the pump and the block. In the case of a two piece housing only rarely have I seen gaskets between the parts of the housing, I think that's because the oil itself is sufficient to seal the gap. I have never used sealant because my fear is a blob will get loose and block an oil passage somewhere with disastrous results.
bentwrench mentioned gear clearances, the 9xx Lotus engine uses varying thickness gaskets to set the clearance, they are different colors so they can easily be identified. Ignore that at your peril if rebuilding one!
Thanks for the input guys. I'm referring to sealing the oil pump housing to the block. In this case its a Suzuki g13b engine, the inner plate that covers the pump gear is gasketless, but the housing to block flange had a paper gasket. The pump it's self is in great condition but I'm struggling to find a replacement gasket. I figured maybe I could use 515 because it will only seal between the flanges, any excess that squeezes out won't harden and would lessen the likelihood of a stray bit of sealant clogging something and destroying the engine. I'll try ringing the stealership and see if they still have gaskets available. Making a gasket is also within the realm of possibility, but I'd rather not if I can avoid it. Rtv is definitely a no go.
I use a thin smear of Right Stuff between Mazda oil pump housings and the engine in order to prevent any air leaks on the inlet side.
IMO, as long as the lack of thickness is not an issue, it shouldn't be a problem. I've had Right Stuff seal 100+psi oil pressure flange to flange. That said, this is one of those places where it would be really nice to have a gasket.
All good, rang the stealership once they opened this morning. $7 list price, I'll be using the gasket. Really wanted to finish the job last night, but oh well, at least this way I know it'll be right.
not sure what pumps(engines) you guys use... but some pumps don't use a gasket....
but they also don't call for a sealant
No gasket between that oil pump and the engine?
Use Hylomar

assume you are talking to me....
no gasket to set clearances... yes gasket between pump and block - no to it being any specific thickness, OEM is coated steel(pretty thin), most(all?) the aftermarket is paper of different/varying thicknesses depending on how cheap the gasket is.....
