This is on an FD race car with an rx-8 eshaft. We had to pull off the front cover to change a separate leaking oil fitting, and now that it's back together the front eshaft bolt is leaking oil(unknown whether it was leaking before, due to the other major leak). The bolt had the little oring present, as well as silicone applied to the flange surface of the bolt. It was torqued to 200 ft lbs. The car also has a solid thermopellet replacement plug.



Any advice would be appreciated as we are trying to make a race this weekend.



Thanks,



Nik

Replace copper washer, check for cracks

Ok, I was wondering about the copper washer. FD apparently does not have one? I was told it did not, and there was none in the engine.

yeah fd doesnt have one. front main seal?

Problem has been solved, It was just a matter of installing a different bolt for the 3rd time with different silicone sealant. No copper washers involved. Thanks to all that replied.

The REW uses a different bolt than older 13b's, and the renesis uses a third bolt design. How much of a difference does this make?

i dunno but they tighten the fVck out of the rew bolt

Let me guess, this is one part the RE shares with the REW?

Yes. The RE and REW use a bolt with a thicker flange and a much higher torque rating. Spec on the FC is 89-98 lb/ft where the RE and REW are 180-200 lb/ft. As has been said the RE/REW don't use a washer like the FC.

But I can use an FC one in the RE eshaft correct?
