I always heard it should NON detergent motor oil, maybe it doesn't matter.

The trouble with that is that a non-detergent is also going to be a zero ZDDP. The ZDDP is very good in this application. For someone doing enough of them, a SA 30 wt oil mixed with ZDDP Plus would be a good option.

I've never seen one, so maybe they don't exist. But does anyone make, or has anyone ever tried the needle bearing type of pilot in a Corvair engine?
I'm not suggesting there is even much of a reason to do so (I never had any trouble with bronze), but since they are available in both bronze and needle roller types for other engines, I wondered if it had been tried and found wanting in 'Vairs.

Thanks

Paul

"never have oiled them". I have never heard that one. I prefer the 2 finger method with motor oil being forced into the bushing (think hydraulic lock).

To Mr. Jamison: I picked up a broken clutch shaft from a vendor at the Toss in Palm Springs for $1. I use it as a clutch alignment tool and as a pilot bushing installer. Were you in Palm Springs over the weekend? There was a guy there that had a bunch of clutch shafts for sale.
