Is this the sound of a stuck lifter? - *** UPDATE 4/8/15****
***** update 4/8/2015*****
Car is back and operational! - see post #31 for a list of what was done. Thanks for everyone's insight and feedback. *********************** ---------- It sounded fine when I cranked it up and then when I arrived at work, it was making this noise. So, it came on abruptly, I have never heard it before. I have been researching it and looking at threads on the forum and I think this is what it is. I have already removed all the belts and it still sounds the same, so it is not any external pulley bearing from the a/c or power sterring, etc. I have about 40K miles on the cam motion cam using stock lifters with Brian Tooley Titanium double springs and hardened pushrods. 80K miles on the car. Does this sound like a stuck lifter to you? If so, what does "stuck" mean anyways - stuck in the up position, down position and is it digging into the cam? Thanks for any insight...

Stuck lifters typically make a tapping sound that varies with engine speed. I couldn't tell about the squeak with your video, but does it vary with engine speed?
Pull the filter and cut it open with a filter cutter. Look for metal in the filter pleats. To me it sounds like an idler pulley has a bad bearing, but you said it sounded the same with the belts off so I don't know. How long has the under drive pulley been on the car? Can you pull it off next time the belts are off? Maybe there is an odd problem with the idler and clearance or it's walking on the crank snout (rare for a non SC car). It's a long shot, but you never know.

That definitely sounds like a pulley. I would try using a listening tube (pvc pipe or similar) and hold it to your ear to listen around the pulleys and valve cover to pinpoint the sound.

I pulled all the belts off the car and it still makes that noise. It does vary with engine speed. I appreciate the insight. THe under drive has been on for about 1 year. It is a PowerBond.

If it is a auto ,check the flex plate bolts .And check to see if the flex plate is cracked. Check the clutch if its a stick .

OK everyone. It was a stuck lifter. I tore the engine down. I have new LS9 head gaskets, LS7 lifters, new CM cam (same specs), new trunnions, BT racing springs, new lifter trays, arp head bolts. Still have a lot of other upgraded hw like pump, timing chain, TF pushrods, ud pulley, arp bolts, etc.....
I will be working on it over the next week to slowly get it together. No rush, I have a spare car to drive. I have read a lot of helpful comments and read a TON about this whole process. Its not really too intimidating now that I had a chance to get intimate with the car. I read to make sure the bolt holes are free of water, debris, etc which I found to be very illuminating. Are there any other minor little nuggets like this to know about before re-assembling... like loctite on cam bolts, anything to do with adding back the anti-freeze, what you do before you turn the ignition for the first time, etc? Not looking for torque spec advice, or how to check ptv clearance, best assembly lube, or any stuff like that, just good little nuggets that shore it up well with best practice. BTW, the car went 40K miles on the cam with no issues other than the lifter. I took the cam out and it looked wonderful except for the lifter lobe that went out. if it was not for the lifter giving out on me, the cam was still in great condition. I use Rotella T6 synthetic and a quart of lucas ZDDP additive with every oil change.

got pics of the cam. I thought it sounded like a loose rocker.

I have a problem similar to this. My video h(in my posted thread) has a tapping...but I have brand new Morel 5315 lifters....
How likely is it that a brand new lifter, with roughly 800 miles on it has gotten "stuck"? Andd....(rookie question here)...How is it possible through the pressure from the springs, rocker arms and down through the pushrods for a lifter to get "stuck"?
