Is This a Lifter? (Video) So I just replaced the timing chain on my car because I kept hearing this strange off rhythm "*****...***** *****" noise. I don't think it was the timing chain despite numerous trusted opinions. I think it was a lifter
Helpful Info:
112k Miles
Cam put in at 66k, patriot dual gold springs (pretty heavy)
Heads never removed, stock lifters
Oil Pump has Fresh O-Ring (from timing chain), oil pressure in car is fine (see video)
Loud ticking noise showed up when I was beating on the car, High RPM pulls

yeah i actually just took the valve covers off and checked the pushrods for play, the pushrod for the intake valve on cylinder 8 has lots of vertical play where as the others have none... so i'm pretty confident that's the issue. I don't know what else it'd be

I'd just use some LS7 lifters they will drop right in but they will require a different length pushrods. The lifter cup height is different than the stock lifters that are in your car now. Hope this helps you.

Yeah thanks for the info, i'll look into like bar lifters, as of now the plan is ls7 lifters. I pulled the block apart last week and found out that a lifter turned, took out the cam, spit needs bearings and metal stuff everywhere, and made the oil look like custom pearl paint. Here's the damage:
This is the lifter:
This is the Cam:
These are the metal/valve seal shavings in cylinder 4
This is the cam bearing:
Based on this I'd just rather get new bearings in the entire motor while i'm at it. It's already down to the short block on an engine stand.
My plan at this point is to try to keep my short block, just get arp rod bolts, bearings and rings, and then buy a nice set of heads, new (bigger) cam, lifters pushrods, and all arp hardware.
Any input on my plan/ good places to get parts, recommendations on parts/cams/shops to do my bearings... anything is appreciated. Thanks

Sorry OP that it has happened to you. That is some pretty nasty damage just take your time do it right and you will be more than happy. As much as I hate to say it it looks like I hit the nail straight on the head. I'm sorry OP I was right.
I had the same thing happen to mine in Dec. Identical to what you posted. I let the car sit for a few months until after seeing your thread. Ripped mine apart last week, same problem. Mine was on Comp 850's though.
