It looks to me that this new comp lifter was bad right from the start.all lifters were just installed got my rockers torqued down spuned it over by hand heard ping the retainer that holds the unit together pop out.In the pic you can see a the good one has the 2 lips that holds everything togeather,the outher has nothing.What the !@#$ happened.I see nothing not even a rough edge were it may have just broken no pieces anywere.I paid a lot of money for there lifters to match up with the cam,warrenty you know witch will likly mean nothing sorry to rant on. has antone had this failure befor.My cam is hyd.i thought maybe i did something wrong pop in an old lifter and all is well now i will have to waite for a new one DAM.
