I just shipped mine back today. Marc gave me a bit of an update at the same time, I hope he don't mind me posting it here to keep people updated with progress

"So far I have found two upper sprockets that are out of tolerance but .002" and the gear cutter said that really should not have an effect given the chain length and diameter of the sprocket. The funny thing is, the two Jon (3400modified) sent back were well within tolerance. The problem appears, at this point, to be the lack of oil grooves in the back of the sprocket causing the chain to run dry and wear prematurely. You can see heat marks (blue) on the back side of the one Jon had in his engine. This shows there was a lack of oil getting to the back side of the sprocket which also slings out on the chain."

cool beans. thanks !

Sorry if that's what his gear cutter is going to say when the chain is walking out of the sprocket that's just not the whole story... One chain didn't fit and walked out 1 tooth, the other fit and only because it was badly stretched.

SOMETHING is wrong, Maybe it's the chain at fault... I don't know, but it's not right. This was not caused by lack of lubrication I can guarantee that.

If you take a bike sprocket and a chain and you wrap that chain fully around the sprocket, it fits... PERFECTLY... This chain did not fit into these sprockets it would center on one roller and then every other tooth after that it would begin to walk out of the teeth. If he is measuring to the profile of a Cloyes DRTC set for the 3.4 camaro and it's coming up right then he needs to measure the chain too and make sure those are the same profile.

No, I have not.

I sent mine back 8/24/13 but have not heard anything. I've tried sending an email a few weeks back (9/10/13) but still have no response. Does anyone have an update on getting this issue resolved?

[3400-95-Modified]

We are coming up on 3 months from when I discovered this issue... I hope something is figured out soon...

Getting real close to building my next couple motors....

[3400-95-Modified]

I sent an email Monday asking for updates and honestly don't expect a response, just kinda hoping.

[1988GTU]

I'm going to give the benefit of a doubt. Hope he's doin well.

[ericjon262]

I emailed him again asking for a response, I hope he's doing well, but at the same time, it doesn't take much effort to send a mass email.

My set is from the original batch, tce stamped, oil grooves, but no advace key ways are cut. For those that done know i got 20,000km on 2 chains, caught the ugly noise the first time, second time it was a knock and sounded like my tensioner was fucked, so maybe its partically my fault, but my top end needs to be replaced now
i'm having troubles getting a GM style chain from a 99-pre motor, according to the parts stores when i brought in a original gear set from a gm motor they told me its aftermarket and doesnt exsist. so i cant even get a melning chain set. guess i'll over night a GM Chain and slap this bitch together. hopefully for the last time.

I emailed Marc again, and still haven't heard back. I hope he's alright.

Find a new autoparts store... I'm using older OEM sprockets and I just picked up a 96 Beretta Chain from Advance Auto. SA Gear was the brand, I also grabbed an SA Gear dampener.

Summit has Melling, but I don't know if it's any good... http://www.summitracing.com/parts/me.../model/beretta

[SappySE107]

I thought the sa gear was junk along with the rest of the aftermerket gears and chains for 94 - 99.

I know AutoZone sells the factory style chains as well. It's the Cloyes brand, even if boxed as Duralast, still Cloyes.

Good luck with the unfortunate repair...
