Weird lifter/valvetrain noise

Weird lifter/valvetrain noise
Hey guys,
I just got back into the LS1 game with a 2001 SS that i bought from a member here on the board. I've been loving every second of it but for the last week or so its been developing a ticking noise coming primarily from the right/passenger side of the engine (valvetrain noise or possible bad lifter?). Maybe I'm just being paranoid but I figure i'd ask before i break something or do permanent damage. Here's a list of what is under the hood and a link to the video(hope it works) of the sound if it'll help...

Again, i hope i'm just being paranoid but who knows...
Thanks for the input!

this is how mine sounded when I spun a lifter and cracked a tray

Mine sounded the same as well. Started making the sound while I was driving though, in a construction zone with no where to pull over. By the time I got it pulled aside it had shut itself down.
After tearing it down found that the lifter had spun 90 degrees in its bore. Lifter tray didn't crack, but was weak enough to let it spin. Destroyed the cam and bent a couple valves.
I'd suggest pinpointing the location with a stethoscope and go from there. Good luck

I wouldnt drive it, just need to tear into it and figure out what it is. Its easy enough to take the valve covers off and see if it something simple, or find out at that point if you have to tear further into it.

Thanks for the replies. i think ill tear in to the valve covers this weekend and see if there's anything obvious. Tearing into an LS is one of the few things that i haven't ever had to do to an f-body in the past. Guess i wasn't running a big enough shot on my previous rides.....

Similar sound as mine, yours is a bit louder. I'm tearing into mine soon and replacing the oem lifters with Morels/changing cam/FAST 92. Might as well if I'm going in there already. My car also seems to drive fine, with great oil pressure. Keep us updated with your findings.

You all are scaring the s%^t out of me. Everyday someone complains about lifters ticking and tearing up their motors. I bought LS2 trays to use with my lifters but I've been thinking bout breaking down and getting the morels..

I have never had to open an LS1 before but i do consider myself pretty technically adept, so other than head gaskets, intake gaskets, exhaust gaskets, lifters and trays, what else will need to be replaced? Also, with head studs can i still get the heads off the car without removing the engine? Im sure there will be more questions to come....Thanks again
