Anyone know this triangle o ring size. Its pretty skinny and slightly leaking.
Dont see any other major seal.




this seal might need replacement but doesnt seem like oil goes in.


Looks like it might also be leaking around the hose fitting.
might try to tighten those as well

I was able to find a replacement for this o ring

are hnbr o rings good enough as replacements. I know they could reach endure temps up to 300f.

Anyone know where I couls purchase the triangle gasket? Is it the same size as the S4 gasket?

You can purchase OMP gaskets and o-rings from Atkins (https://www.atkinsrotary.com/Mazda-G...s-and-O-Rings/).

@Hot_Dog
thank you! Ive actually seen those but im looking for the odd shaped one. This one.

I just replaced mine a few months ago. Bought the replacement from Atkins. The o-rings are oval when new. It will conform to that odd shape once you insert it into that groove. Recommend using silicon grease to hold it in that groove.

@Hot_Dog
do you mind sending me the link. I accidentally bought the oring connecting to front cover. Atkins does have a 79-88 rebuilt kit but I have a an S5 91 oil metering pump. Does anyone know if these orings will fit the S5 o MP?
