Carquest part number for front main seal in the RB motor is;

[240z4u]

Its a Victor Reinz gasket and the part number is 66991. Listed as a z32 cam seal (as I was told by you guys).

Hope that help someone.

How tight of a fit was your gasket? I put mine on over the JUN crank collar and it seemed hella tight and now it is leaking slightly. Yes, I just typed the word hella.

I definitely would not say "hella" tight LOL

It slid smoothly over the snout of the crank. I literally pushed it into place with my fingers and the timing belt pulley. Fit like any other seal of that type I have installed.

I did NOT have to force it. I had my crank snout extended by a machinist who welded on material then ground it back off. That left me with the normal factory dimension snout.

If it was too tight, I imagine it would tear up the seal. You may want to make a few phone calls after measuring the OD of your snout to try to find a better fit.

Get that thing back apart asap, it makes a tremendous mess. My timing belt was kind of "sticky" when I took it out
