I have same prob, wore out cam gear in 10 miles.
Help, this is an expensive build with edelbrock pro flo and much more. New everything, except timing cover. It seems to be in great shape, no visible wear. I think the oil pump set might be the problem. It seems to be tight, it feels funny like the gears are pulsating when turned by hand. They can be turned by hand though, so I dont know if that is considered loose enough or not. The oil pump gears seem to be slightly above the deck of the oil pump surface, so I will get some plastigage tomorrow and measure the tolerances.
I also ran 5w30 not knowing any of these issues before hand. How likely is that the cause? I never heard of oil causing extreme wear of this nature?
It is brand new motor, and I had great oil pressure after priming. I am sure it is a tight motor and I was worried about running too thick an oil and blowing gasket and seals.
MC what is your reccomendation from here?
I need a matched set of gears.
OK, frustration setting.
I munched a second gear now. Its been 60 miles or so and I pulled distributor to check it out. I can see the wear straight down the center of the cam gear. It not broke yet, buts it's a few miles away. Looking at the pictures of your gear, it seemed to have flatter surfaces where the gears mate. My cam gear(both) from Mopar seemed to have tapered mating surfaces. I ran stock oil spring, and 10w30. max 2500 rpm. still breaking engine in. Oil was 60-65 psi hot, 70 psi cold at 2000 rpm.
How do I get matched gears from MC. ?
I still need dizzy gear set
MC, did you get any gear sets in yet? I also saw some posts about development of cam buttons last year.
I would like a button as well just to be on the safe side, although I don't beleive I have that issue, I am trying to eliminate as many possibilities as I can.
Please get back to me, I have had my daily driver in the garage now 4 months.
again, I need a cam/dizzy set and cam button.
