Mark,

Hydraulic lifters have been a problem for about 5 years now. Everyone
who made them, or
made good ones got bought out. The supply is getting thin and no one
wants to manufacture
them. All the cam companies are having problems getting lifters, and the
quality has been going
down for a long time.

Hey all,
 
The next sentence will give you an idea of what kind of week I'm
having...
 
I was coming home from jury duty Friday night when I suddenly got a loud
clacking and engine miss in my 360.
 
This is a motor I built just about three years ago and have put about
6000 miles on. I'm running a very mild Comp Cams Xtreme Energy cam XE262
with their matching hydraulic lifters. Pulled a valve cover and one
exhaust lifter was obviously collapsed. Pulled the lifter and took it
apart and a little spring steel plate, probably about 1 mil thick, that
should be just below the plunger cap was in pieces resting in the bottom
of the lifter body.
 
Hmmm. This has me nervous wondering if these particular lifters are
prone to fatigue like this and others are going to go south now on a
regular basis, or if this is an anomaly. Anyone else have these lifters
and experience a similar failure?
 
For now, I swapped in a new lifter and went back through the break in
procedure. Running fine now. Wondering, though, if I should swap out all
these lifters.
 
Thanks! Mark
