Should I Worry?.. (pics)
Should I Worry?.. (pics) My Oil drive gear got whiped out from it having 182K miles on it and trying to push some thick oil. I pulled it out today and saw it marked up the cam gear alittle. Its a full billet cam that i got from LE with around 8k miles on it. Should i worry about the cam gear messing up the new oil pump drive gear? Im going to find a GM drive gear unit, hopefully thatll hold up.

You'll be fine. Just went through this on a friends car. It has a cast cc306 in it and it took all the drive teeth completely off. I bought just the drive gear from oriellys (just had them look one up for a 96 chevy pickup) it was made by borgwarner.
We put it in, along with a magnetic drain plug and it has been fine ever since, oil is clean and we havent had a problem with the cam as long as having great oil pressure.

I think its more the high mileage gear that does it. I used a stock 145k mile drive gear when I had my hotcam in (they're billet as well) and when I pulled that cam out the drive gear was paper thin and ready to go as well.

I have the older Comp ground LE1 cam and I have maybe 10K -12K on it with standard flow pump. I inspected the oil pump drive last year and it only showed light surface wear to the faces on the tooth that many I am sure would call normal. I recently looked at my original drive gear from the 60K stock motor and it showed a bit less tooth surface wear than the current one.
The wierd thing is I am still getting numerous very fine ferrous particles in the oil filter after each oil change. I was geting some wear on the old push rod guide plates but those have been removed and replaced by new Isky ones of much better quality. I am confident the particles were coming from either the guide plates or the oil pump drive gear.

I just pulled my valve train off and so far everything looks to be in perfectly normal shape. Im going to pull the rear 4 lifters apart to inspect and see if theirs any metal shavings inside. If not im going to let them sit in oil until i put it back together again.
I am going to be pulling my drive stub soon to install your bracket and I might go ahead and throw the gear on at the same time. But first I will do an in-depth examination of the current drive vs. the original one from the stock motor.
Ill be much happier when the engines back together and running. Hopefully with good oil pressure! Im going to be installing a little oil psi guage to where the sending unit screws in at the back of the block. That way when i prime the oil pump i can know for sure that i am making pressure.
I pulled apart the valve train after work today. Everything seemed to check out in good order. There was only one thing that really irked me. My intake manifold was Filled with oil! IDK where it came from, i mean i have 2 water separators in line with my PCV valve. I dont have any pictures to illustrate it, but take my word on it.... it was BAD... i left my intake on a table on one side and when i went to move it afew minutes later there was a big puddle of oil under it. Im wondering if i have some sort of vacuum leak....... hmmmm

"All of our grinds utilize the vastly superior 8620 Induction Hardened Billet Steel cores found in all forms of serious competition. Additionally, all of our Billet core custom grinds are automatically upgraded to a premium EverWear distributor/pump drive gear. Not only is the EverWear gear precision machined to significantly tighter tolerances, it is also case hardened with a proprietary nitriding process. Compared to commonly available cams ground on the cheaper cast cores, these features translate into improved reliability. This is especially true where heavy weight oils, higher volume/pressure pumps, and various aftermarket distributor gears are used."
