I'm guessing there was no warning when they let go, and it just "happened"

This sucks. My LS7's are 2 weeks old. **crosses fingers**

I had plenty of warning, started with a metallic tap that just eventually got worse with mileage. Also notice tiny bits of the metal from the roller on the magnet of drain plug.

Don't sweat it, I think you'll be fine. For the few well-publicized failures we read about there are hundreds of successful LS7 installs still going strong.

Same thing with noisy lifters - lots of people out there with quiet LS7s. Unfortunately I'm not one of them.

If and when mine go, I'm going straight to Morel / Lunati and that's going to be the end of it.

LOL, right now my intake is off along with the valley cover. Haven't pulled the heads yet. Dunno if I want morel link bar or regular. I don't beat on it much and currently have a stock LS6 cam. Might go link-bar for future upgrades, but I might swap in a cam now also. Not having to worry about a twisting lifter is a plus.

Let me reformulate it if you don't mind.

None link bar lifters will not twist except in the case of a wrong valvetrain set-up' and this until above 8500rpm...been done for years on LS engines.

Link bar lifters will never ever twist, as with a wrong valve train set-up, but destruction of valve-train components will happen, sooner or later, even quicker if you rev your LS engine above 6500rpm...still happening everyday.

good points,

My rev limiter is set to 6500 and I have never hit it, 5500 is the highest I have gone. Brian tooley springs site has the link bar morels for $499, im sure they can get the non link bar ones. I will be contacting them.

Crap. I was just told by a well-respected LS guru & member here that I should just use LS7 lifters for my application. Said Comps aren't as good and Morels will be noisier. Now what do I do? If I still have ticking with new LS7's and new cam & heads it's time to hide the razor blades . Did I just get a couple of "bad" LS7's or what?

My LS7's are noisy too. My buddy thinks I am crazy and being paranoid but I can definitely hear the valvetrain over my dumped down pipe, ha. Mostly between the 1500-2000 rpm range. I am going to let it ride though and see what happens.

That seems to be the sweet spot or rather the unsweet spot LOL.
