Oil pump drive gear

**96speedZ28** · 06-18-2013, 05:12 PM

Well my cam ate the drive gear. I am trying to figure out which gear to get now. The GM melonized gear or a composite gear or maybe something better you guys know of? I just want some LT1 guys opinion who have maybe been in my position before I go spending money. Any help would be appreciated!

The cam looks to be fine. Here are some pics, what do you guys think?

I don't remember the part number but when my CC503 ate the cam gear I bought an everlast distributor hardened gear from Jegs.

IMPORTANT ... were you driving when this happened and did you drive very far once you noticed you had no oil psi

What gear did you have before and what cam do you have?

When it happened to me I had a stock gear and it was a CC503. It's a known issue where aftermarket cams will "eat" the stock oil pump drive gear.

How hard is it to change the oil gear drive?

There easy to change it. Once you get the intake manifold off. OP Get a GM melonized gear. Its what GM suggests useing whenever you do a cam swap. I was stupid and didnt realize that until after my LT1 chewed through 2 came gears. The first was the stock 180k mile gear and the next was the POS! Lunati Everwear. I had the dreaded stamped 13 unit. Which if you do research on was a bad batch from the manufacturer.

Hrm, I have the Lunati Everwear gear in my car now. It's only been a few thousand miles though... hope I don't have issues with that.

I was just cruising, saw the 'CHECK GUAGES' light come on and I put it in nuetral and costed to a stop and shut if off. I started it 3-4 times after that to check thiings like loose wires and if oil was pumping up to the heads. The last time I started it, it sounded like it had a stock cam. I am guessing the lifters bled out. It ran maybe a total of 2 minutes after I saw the guage read 0.
