Distributor gear oiling.......
It is very important that the distributor and cam gear are properly oiled..if not they will chip, break or wear very fast and the pieces end up ruining your oil pump (timing cover) and eventually end up opening your oil filter bypass and damaging bearings,crank,cam,lifters and in some cases spleening your roller rocker bearing. Here is a pic of where why and how oil gets to your cam and distributor gear. The large timing gear (upper gear) depending on the manufacturer MUST have these oiling holes or grooves with a recess on the other side facing the front of the engine for oil to reach your gears....Lets take a look

Oops wish I saw this before I posted in the engines section; that is the same gear my 343 had in it TRW. I had been runnign a replacement MSD distibutor with no problems to the cam gear or supplied installed msd disy gear, with the TRW sprocket.
By comparison the rollmaster timming gear has the grove oil channel design on the inside diameter of the cam hole. It also has the multiple groves around the outside diamater of the hole. However I noticed the summit gear has a "cup" where the "hole" in the TRW gear is, I assume to channel oil, but the rollmaster simply has the grove in the inside diamter if the gear without the cup?? Why does the summit gear have that "cup" and the rollmaster does not?
timing gear oiling channels
I looked at the rollmaster gear and it seems like they took a unique approach to the oil path design. Instead of a hole or cup for the oil to flow through they machined a 1/4" recess around the outside diameter of the cam hole, this would take care of ANY alignment problems that have plagued other manufacturers designs, the mating oil channel could be anywhere within that 360 degree channel and oil would be forced into it, THAT was a design! :lo1l:
