Low oil can also cause lifters to collapse. The first thing I'd do is change the oil and filter. That way when you're checking for the noise, if it is just a lifter or a broken rocker or something you'll be running it with clean oil.
Changing the oil will also let you see if there is any metal in the pan or any other indication of damage.

question for you. If you collapse a lifter, is that lifter done for or can it "un-collapse"? Do you have to have zero oil pressure to collapse a lifter or just low volume?
Thanks

The expensive part is all the labor, but you could do that yourself if you are willing to take this on as a learning project and buy a few tools. All the tech you need is right here on the forum.
violator, if your anywhere near cherry hill, than your about 3 hours away. not to bad of a drive (i like driving) let me know what you find or what you want to do, and we'll go from there. For instance, if your problem is a lifter and you don't want to pay out the *** for labor, I will be more than willing to drive to help a fellow member out. (for your reference, i'm only 24, but have 7 ls1 head and cam swaps and about 5 or 6 plain cam swaps under my belt-not to mention like i said prior, I am a mechaninc)

Just for the record! I had the same thing! Mines was much much worse (i think) I heard the same noise! Took it to the dealer! My clutch was gone bent rod and bearing! Over all I got a new LS1....Damages and Labor = $5000 ...so they just said **** it and gave me a new engine! Had to pay $1200 for clutch and tranny!

i'm **** outta luck too , i know my lifter is toast again, but i'm unsure how to figure out if i have spun a bearing without replacing the lifter and then starting it up and finding out the car is still broken as i have already replaced it myself once and it isn't the most fun thing in the world to do.
