Also if you run a vacuum pump set up it helps seal your cylinders up and pulls fuel out of the oil by raising the boiling point, increasing your oil life.

I don't -really- have a "race" car. Just rally and autocross. The Subaru rally car gets Rotella T6. I'll use the same stuff in my MX-5 powered Mazda Rally truck when it's completed next year. The autocross car gets Torco. I've been using SR-5 and V-Series-SS. I went in with a friend and bought the remaining stocks from a distributor and still have a few dozen cases. In the late '80s I used to autocross an F-Prepared Datsun 240Z. It was an extremely loose engine with very high compression. That engine got Mobil-1, which was about as good as it got back then. And it got changed out fairly often too. But I was inside the engine about every fourth event. |
Anyone know if NB bearings can be repacked?

What was different about the rears on the msm? I replaced my rear bearings with standard issue Napa bearings.
I would give mad props to anyone that can get the rears out without breaking the bearing. The outer race stayed on the hub when i pressed mine apart and everything fell to shit in the bearing. |

The center race coming out with the hub does not mean its damaged. The outboard race usually does not want to come off the hub so I simply clean it off, then bolt it back together. Its good insurance to repack the rear because changing them out SUCKS. |
