Lifter Damage Poll. (Please chime in even if you've never busted'em up.) If you've chewed up some lifters or have some "ticking", please explain what you believe caused the failure.
Please include pertinent info such as, but not limited to:
A) how many miles were on the engine?
B) your driving style?
C) which cam you were using?
D) whether or not you bent push rod(s)?
E) were you running the engine cool (160* t-stat or whatever.)?
F) etc...
And on the contrary, if you've never had any lifter problems, please give some details about your set-up and what you think may have contributed to your set-up being a low wear system.
TIA

No lifter problems on either my B1 cammed (221/.558) WS6 or my stock Z28. Both were/are low mileage motors though.
I've always run synthetic oil (M1), use a t-stat (stock or Hypertech 180) and fan settings that keep the coolant temp in the ~195-205*F range, never bent P-rods (both auto trans cars), and never go over 2500rpm till the motor/oil is fully warm.
I used to rev my WS6 to about 6200rpm with the B1 cam, 26918 comp springs, 772 ti retainers, and hardened P-rods.
My Z28 is revved only about 100rpm over stock, and is using a stock rev limiter and stock valvetrain/stock cam.

I have done a lot of searches on this subject and have found that most failures are related to spring load. Perhaps you should find out what springs/cam/rocker setup they are running. I have kept tabs of this issue in a spreadsheet and found that open pressure seems to be a key factor.

bad lifters... A) how many miles were on the engine? 45000
B) your driving style? Easy
C) which cam you were using? Stock
D) whether or not you bent push rod(s)? 3-slightly bent
E) were you running the engine cool (160* t-stat or whatever.)? 160*
F) Etc...
Yep, I have some bad lifters. Dont know how many for sure. Been ticking for awhile now. But its my DD and been low on $$$$ to open her up. But taking some leave next week for the holidays and I'm pulling the heads and cam and replacing all. Been on stock valvetrain since I got the car. I think they went out when I was on the highway when my tranny lost 4th gear and it droped to 2nd. Not fun. When I pull the heads I'll give more info.

Installed a MS3 with LS6 heads, stock length moly pushrods, stock rockers, stock lifters. Engine had 80K on it, I bought the car from my mother so the miles were extremely easy miles from driving it MO to VA. Regualr conventional oil every 3K miles. Anyway, at the time of the install, I didnt rotate the engine over and go back through and check the rockers TQ. I drove it down the street and it started ticking. It was coming from the front of the d/s bank so I pulled the valve cover. Turns out the #1 intake was open when I TQ'ed the rockers and it didnt get tq'ed right so I was really loose. I rea tq'ed ALL rockers, rotated engine, did it again and drove it. Ticking would come back every few miles and go away with low rpm driving or idling. Now it only comes back if I spin the engine up to the 6K or so mark then goes away after the same idling or low rpm. I bought some lifters to replace all of them but am going to wait to pull the heads back off until I get my headers next month.
No bent pushrods, engine was operating temp, driving it easy at the time of the ticking

Had 4 lifters show some pitting at 88K mostly easy highway miles, 10K with an f13 cam on a 2002 car. One lifter was really bad, one cam lobe showed some scratches, but i didnt replace the cam. 3K on the new lifters, so far so good. Will be opening her back up in the springtime for a headswap. Ill check the condition of the cam and replaced lifters at that point. I run a stock thermostat but my fan clicks on at 200.

less than 50k miles. Ticking started a while ago. Now that i have a bigger cam i can hear it more. I dunno what's causing it. Now i'm assuming it was a lifter.
About 300 miles ago i swapped the cam and it got a little louder.

A) how many miles were on the engine? 72,000
B) your driving style? usually easy but I work it out weekly =)
C) which cam you were using? Stock cam
D) whether or not you bent push rod(s)? Nope
E) were you running the engine cool (160* t-stat or whatever.)? Had a 160* t-stat in for just over 1,000 miles - no problems yet.
My low wear's probably due to a lot of easy driving and a basically stock engine. Also, changing the Mobil 1 5w-30 every 3-4k miles doesn't hurt either. The engine does tick pretty loudly - especially on cold startups but the car runs well on the street and the dyno so I'm assuming that's just good 'ol piston slap. Future plan (basically a pipe dream at this point) is an LS2 402 stroker.

Please include pertinent info such as, but not limited to:
A) 45K , 60K
B) Weekend cruiser / 1/4 Mile car.
C) First time stock cam 2nd time TSP 224R.
D) 1st time 4 bent and 2 bent valves 2nd time hardened pr none
E) 180* t-stat
F) Both time mechancial over rev caused the damage.
I replaced the whole batch as insurance that I would not have to crack the whole thing open again because of a bad lifter. It is possible that I did not have any issues but I will have to send the lifters out to be tested to be sure.

Please include pertinent info such as, but not limited to:
A) 65K
B) Daily Driver 5 x summer track
C) FM 13.
D) Lifters became spongy, rung cam bearings
E) 160* T Stat
F) 7.4 PRs too long...7.35 was correct, worn bearing from???
I blame myself to a point...did cam/head swap with 65K miles...probably had some cam bearing wear...the new spring pressure probably killed the bearings,,,the long PRs probably killed brand new CompCam lifters.
