New timing chain tensioner problems.

Hello everyone. New here, and getting a little desperate. I've been through multiple timing chain tensioners. The most recent from the dealer, lasted about 800 miles before I started hearing rattle again. I replaced chains, guides, tensioner, etc at Christmas this year (about 15k ago) since that time, the 1st tensioner (from autozone) went bad and made my chain skip. Put everything back together and installed a warranty autozone tensioner, and it started rattling writhing a week or so. Pulled a old style tensioner out of a cobalt I had with 90k on it, and used that (very noisy) until the dealer one, which led me here.

Thoughts?

Thank you!

I've had no problems with the new style ACDelco. All my Cobalts received this ''B'' version as soon as I acquired the cars.

I understand that it "shouldn't" have problems. Issue is, it does. Which is what leaves me baffled.

So your last tensioner was the new version with the bump on the head and you're still having problems?

Yep. Still with the rattles. I got about 6-700 quiet miles out of it. Now it's worse than it was. Rattles sometimes a few seconds then goes away, sometimes longer.

I really don't understand, it can't be a coincidence, are you sure the oil galley leading to the idler tensioner isn't plugged because it just doesn't make sense. If the new design has failed for you it's the first one I've heard that failed. Not impossible, but for it to happen to you after all these faillures would be a million to one.

How would I figure this out?
