I can't say my lifters are toast, but my Comp Cam doesn't look real great after break-in.
What does that mean...you've had 3 sets fail? Or 3 sets of lifters have worn more than you think they should have?
If that's the case maybe something else is going on...
Bottom line, if you don't feel comfortable using Comp products, don't use them!
Be aware though, that the overwhelming majority of cam/lifter brands source their parts and cores from the same company(s).

more than one in each set have collapsed . pushrods are still spinning. it was a kit with springs lifters and cam. did as thay said to break in and that part seems to be ok. wondering if cam will live thro a 4th break in with in 500 miles.

I wish you the best of luck. I just successfully broke in a lunati flat tappet cam. Make sure the lifter bores are clean, make sure the lifters spin. Use break in oil, very your rpm with a snap of the throttleoh boy will be breaking mine in about a week,

I'm not sure I understand. You replaced an entire set of lifters because a few collapsed ? And then you replaced that set too? And then another set ? Why not just replace only the defective ones ?
What a pain. A friend has replaced a half dozen Comp lifters on his 440 because they collapsed. One at a time.
if 4 went by by why won't the rest later???
Just a thought @hacksaw......if different sets of lifters keep collapsing......is the spring pressure correct? Have the springs been tested and setup properly? You just can't go by the paper specs unfortunately. I've not had problems with anyone's tappets but everything gets checked and tested to the point of compulsiveness...that does not mean you can't get a bad one though.
But bad ones in three different sets? That's suspicious enough to get me looking elsewhere..
if you want to use the best tappets currently made call Mike Jones @Jones cams and see what he has. He used to keep plenty of sets of Hylift/Johnson in stock but if not he can surely point you in the right direction.

ya .. i got his number ... the springs are ok. and the first set went bad before i put the inner spring back in. this seems to be a not just me thing. and not just a comp thing nether. just shitty parts got in the system during/after covid do to not being able to get any parts.
Well I won't the argue the "shitty parts" deal, that's for sure! My point was we just have to be 1000% more attentive when putting stuff together these days...you're one of the good guys around here, I wish you much success!
ok .... just a FYI ... here is a set of NEW comp cams 822 hydro lifters...
pic #1 as you can see there is NO swirls on the face and is flat..... #2 has come pre flat with a dish in the face of it .... #3 has 2 dips in the face and no swirl marks ...
these are what is coming out. only 6 had a taper of 1-1.5k needed to make them work as thay should.

Junk. The ones without a crown won't turn in the bores and will wipe out a lobe.
at this point it don't matter who or where thay came from to sell us. no way in hell this should have been shipped out to a builder.
i sent them these pics ... as of yet have got no reply
