Took off my oil pan today and found this
 

I took off my oil pan to install an oil pan brace and I found this. Ive yet fully disassemble a rotary engine so I am at a loss on what it is , and it has me scared that I will need an early rebuild.

Looks like an eccentric shaft oil jet. Have you had loss of oil pressure?

I can only guess it's the middle one and fell down the bore in the intermediate housing.

that's what I thought is might be, but shouldnt it have a hole through it? My oil pressure is good.

If this is a 2nd gen engine its the oil pump set screw...

Thanks! That is exactly what it looks like, but what is its purpose? Can i just take off the front cover to replace it?

Turblown's got it right.

The set screw keeps the middle plate (7) from turning. Oil pump wouldn't pump very well if it does.

How 'bout that. I bought a junkyard engine years ago and found the same thing laying in the pan. It needs to be staked into the oilpump body so it won't come out.
