yes

O-RING - OIL SEAL OUTER 0820-11-341 4 Green

O-RING - OIL SEAL INNER 1202-11-343 4 Green



- do not use 8341-11-343 black o-rings.



From MAZDACOMP






Reffering to the items above. what are these made from? I have the viton oil rings from RA that I am using. I have had to pull the motor out due to excess blow by. After reading this thread, I am considering using the stock oil rings when I put it back together.



Viton is better at standing up to chemicals like petrolium vs silicone, but silicone is better at withstanding heat. Are the green factory oil orings just silicone, or are they teflon encapsulated as mentioned above?

Fc3S.org went out on a limb an ordered a ****-load of the Correct sized viton O-rings from an unnamed source. I will have the Correct Sized inner coolant O-ring in a few weeks. https://www.nopistons.com/forums/pub...IR#>/smile.png




Not once, but 3 times https://www.nopistons.com/forums/pub...#>/biggrin.png I have had really good luck with my o-rings, especially in engines that have higher oil temps. Stock is always a good recomendation. Sometimes there are parts that are better. Mazda builds these in production. If they upgraded every single part they could, the cars would cost $250,000.

are these Mazda Green seals the ones that are black with the green band. Like Green on Black. rather than the all black ones?
