Detailed Description

This kit provides all the typical minor consumable internal seals and springs required for a quality rebuild. All parts are genuine Mazda factory, except for the substitution of our Heavy Duty Water Seal Kit and Ceramic apes seals. Kit includes apex seals (OEM 2pc.), long & short apex seal springs (OEM) side seals-"cut to fit" (OEM), side seal springs (OEM), corner seals with plugs (OEM), corner seal springs (OEM), oil control ring o-rings (OEM), oil control ring springs (OEM), Cut off seal springs (OEM),  Heavy Duty Water Seals, front cover gasket (OEM), Oil pedistal gasket (OEM),  rear stationary gear o-ring (HD), front & rear main seals (OEM) and more.

The options above allow you to add Bearings, Rotor Housings and Oil Control Rings to your order, which are otherwise not included. Bearings are generally replaced on a quality rebuild, but not always required depending on the condition of the existing bearings. Installation requires a press and special adaptor. Rotor Housings are very expensive but are mandatory for any rebuild expected to last and start well when warm. Used housings should be carefully inspected prior to re-using, in any event. Oil control rings have a fairly long life and can be re-used if within specification (0.020 inch or 0.5mm) of wear. Just measure the shiny part on the wear surface. While the rings themselves are not included in the basic rebuild kit, please note that the oil control ring o-rings and oil control ring springs ARE included.

If you do any price shopping, please remember that many places will sell you a rebuild kit with substitute aftermarket parts that are inferior to OEM. The most frequent substitutions are apex seals and oil control ring o-rings. Please don't fall for this. No aftermarket metallic (as opposed to ceramic) apex seals or oil control o-rings come remotely close to performing as well as the OEM parts. This is why we don't offer them. The only substitutions we typically recommend are premium ceramic apex seals (only for extreme applications) or the Heavy Duty Water Seal Kit (for all applications), which we tested for 7 years in a variety of engines on the street and track before offering to the public. Our HD water seals have seen coolant temperatures over 240*F and survived in real world situations. While we do not recommend running an engine at these extremely elevated levels, it is nice to know a temperature spike will not likely result in a water seal failure.
