cam gear oiling
 

Any of you guys ever cut a groove, or drilled a hole, in a distributor shaft to add extra oiling to the cam gear? I was thinking of doing this, and positioning the oiling groove so that its aimed at the cam gear.

I drill 3 small holes. One in each end cap of the lifter oil galleys and one in the oil galley going to the front cam bearing. The ones in the lifter galleys caps are to prevent vapor lock of the oil to the front lifters after the motor has sat (like boat motors tend to do. Another one in the cam bearing oil galley so there will be oil behind the cam gear that way the hardened spacer (roller cam) wont burn into the block.

Im talking about the distributor being modified to oil the dist/cam gear better .

I think he is talking about a slot in distributor body to put pressure oil on dist gear to cam gear interface.

I never have but don't run the oring on the lower of the distributor. I figure enough oil will seep by.

MSD dist has the oiler hole, but I never paid much attention to where it was pointed. Then I installed my cam this time around and found the gear was damaged. The dist will go in as a cam sensor so I can orientate the oiler hole right over the gears and should have good lubrication to them. I have done the slot thing before also.. I believe it is a good idea..

i have never done it,also never had any problem with gear ware on cam or dist.i believe the gears get plenty of oil already,jmo.

No o-rings and slot; no issues with bronze dist gear wear on my engines.

I remember crane cams had a tech bulletin about doing the mod/groove. Apparently it helped lube the gears much better, and last much longer, especially when running a high volume oil pump. I seen some guys claim even their bronze gears living much longer after the mod, with a direct spray of oil on the gears.

I know on my 454 vortec truck engine, it was advised to pull the distributor at 100k miles, and take a look at the gear. I pullled mine at 90k miles, and sure enough, the gear was done. The teeth were razor sharp and worn big time.

Just one of those easy mods, i cant see hurting anything?

You have a groove cut in the shaft ?
