Tore engine down as its well overdue having around 15000+ miles on a well abused 10 second 406 pumpgas combo.. It has uncountable passes, and none of the steet miles are easy by any means. .After tearing off intake just an hour ago, found than link bar cap had come unscrewed from threads and lifter had turned and lunched itself quickly. With a slipping clutch and that the car ran 10.08! WTF! Clutch had also worn down to rivets after uncountable 6k+ launches at track and lots of street driving. Was contemplating a new cam, guess its not an option now.. Guess is this had happened just on the first pass last week, on second pass header gasket had blown out, I assumed it was due to the bolts needing retorqued and racing with muffler on as of late it had enough, it blew out on #5 where the lifter was. at that pass is was lunched but could not hear due to gasket.. Next pass yielded the best 60ft time ever, then clutch finally died - probably good for engine though.

I've always discovered my car runs it's fastest right before something lets go. I still haven't pulled the oil filter off after the season so see if there's any metal in it. My last track day did net me a new personal best. That's what scares me based on previous history.

wow man, cant believe it! All that hurt and still ran strong! So i guess you need to replace all the lifters now and stay with the same cam? Not a big deal i guess, fresh motor with that cam will run stronger than it did few weeks ago so you should be well into the 9's, especially with new clutch

What brand lifters thanks

Crappy :/ Had sort of the same deal happen with a set of lifters except I never even got the car on the road before they fell apart. The rivet holding the linkbar to the lifters wasn't swedged on one. The lifters turned and took out the custom ground camshaft. Sent everything in to Lunati and they took care of replacement lifters and reground the camshaft. When it happened, sorta sounded like a loose rocker and lucky me it was at an idle.

Good thing it was cought early for you, my link bars have a screw and nut that hold them to lifters, the threads we fine except where srem had rubbed block after turning, so it simply came loose over time.. Something I will check now going forward..

GTANUT:
They are comp cams solid lifters, I am going to contact them, though they will likely not take ownership after my years of use, its worth a shot - they have been great lifters other than that.

ORR:
I did not remove cam yet, it is surely wasted though, it wore the roller down to body then wore both on that short amount of time. The last pass the car was cranking slow, I know why now!!! the lifter was sideway with 420lbs against it killing the cam.. I don't know how much the cam hurt, as I think the 10.08 pass was mostly clean, but I am pretty sure I will pick up 2/10s with clutch alone, you can hear alot of slip on shifts..

Steven :Thats always in the back of my head, I have had it happen as well and heard of way to often..

I've seen more comp lifters break than any other lifter.

I have always been told that solid roller lifters need rebuilt or checked at least every 200 passes to be safe.

Just my $.02!

i have ran comp cam solid roller lifters for a long time.. never any probs.
but..and i will say But! i have not taken the top end down to see what it looks like..from the last time the eng stopped

I have checked them prior, but never checked that the linkbar screws are still tight. I will now if I retain these ones, they do not seem worn at all other than the 2 bad ones now.. I would say they have given a good life, but this was an acknowledgment to those with them, would hate to see someone else toast a cam due to this..

ARTICWHITEZ: Check them over the winter, I would never had known..
I would use comps again, the link bar screws now concern me some though.

to tell the truth.
who makes them for Comp Cams. i know there is only like 2 makers of lifters.in the U.S. if i remember right.

but as soon as i take my top end off ill check all of them..

Not sure, I assumed that comp was the manufacturer.. Just pulled heads off and checked the rest, there were several loose..

go back to a hydraulic roller

havent taken mine down to take a look.. just lazzy..and it's cold outside.

compcams when i picked up my last set. they told me they have them made for them.. forget the name of the Tool comp.
