Which oil control O ring is better between the original MAZDA and th Atkins?. I know that the Mazda is silicone coated with viton and the Atkins is pure viton , but which would really be better for use on my motor?.

 

If I'm not mistaken viton is more heat resistant so my guess would be the atkins is better.

 

Thanks Kyle for your reply.If anyone else has any more info , can you please post it ?, I need to order soon !

 

I understand that the inner O ring is much higher spec than the outer (a friend had a factory set analysed). In fact the outer was nothing special - he found a local after market supply for a much cheaper price, with the same qualities/heat resistance etc etc (just a different colour). Going to be tried in the next race motor re-build...

 

Hey Marcel Burkett, a friends RX3 coupe (bright yellow 13B injected PP 13x10 wheels, cage etc) full race car was sold to someone over your way from New Zealand a couple of months ago... do you know anything about it???

 

Viton is good stuff. I made my own water seals using viton cord.
