2.5 years, six passes and roughly 3k miles. Cold oil pressure would run 80 PSI. After the change from 20w50 to 10w40 cold pressure is something like 65 and hot idle is 25. Been checking the gear every Spring since and it looks like it's wearing OK. Don't drive the car too much anymore though.

No idea what the clearances are in the motor. Would have to find the paperwork from the shop.

An update to this thread i start. I changed the gear and bushing, i changed to Hughes "melonized" gear and i have drive it for about 800 miles more now and checked it, it has no visible wear at all now on both intermediate shaft gear or the gear on the cam and i drive this engine with a Milodon high volume/high pressure pump, external oiling and Valvoline vr1 20w-50. Hot engine just over 20 psi idle, 2000 rpm just over 40 psi, 3000 rpm 60 psi and so on. Main clearance 0.0033" rods 0.0028" and pushrod oiling aswell as oiling from number 4 cambearing through the rocker shaft. Its running great.

To me the cam looks to be extremely worn in the are area indicated. I've never seen a tooth profile like this. The profile of the cam teeth should match those on the intermediate gear which has a "V" pattern

The teeth have a bevel so it looks like wear.

Look at the lowest tooth to the right, down low.

In that case the cam gear was worn out as new. The gear looks the same when i installed the cam new. See the added pic with the cam installed with a bronze gear, its the same.

No metal in oil, but it sure was with the bronze "sacrificial" gear

An update again about the melonized gear, i have drive it for another 1200 miles and the melonized gear looks same as new, no visible marks at all, same with the cam gear and nothing in oil or oil filter. So about 2000 miles with the melonized gear so far and no wear at all. I drive the milodon high volyme pump with external oiling and Valvoline vr1 20w-50.

Good news, thanks for the update.

I just installed one in mine and fired it yesterday with a new roller cam install.

Will drive a couple of times then pull it to check.

Im sure it will be just fine. They are so incredible much better than the bronze gear, no signs of wear after 2000 miles, the bronze was toasted after 600 miles.

I probably go through 1 bronze gear every two years on a 493, HV oil pump, NSS car. My machinist suggested the melonized gear, but when I contacted Hughes, they said it would wear the cam (custom solid roller), so I elected to just stock up on the bronze gears.
