how much and where ,2mm or 3mm?might need to rebuild asap ... anyone thanks

 

Just use Mazda OEM seals, they are the best for general street use. You can use Mazda 3mm seals, but the rotors will need to be machined out to accept the wider seals. You may also need new housings or other parts, depending on the mileage of the engine and how it was blown.

 

yes always use oem seals or those crazy *** ceramic ones if you have the $$. i hear all the other seals are pretty much crap.

 

I would use much of the factory seals, but I also would rec. seals from rotary aviation. They've made the two piece apex seals which are stronger than the factory seals, but stick with the factory apex seal springs.
