Just wonder if anyone else out there have had any problems with Comp cams hydraulic roller lifters? I just had 2 fail in my motor.
Couple weeks ago a heard a ticking sound in my motor. Thought is was a leaky header tap or a lifter. Pulled valve pan cover and #5 exhaust valve was ticking. I reset all the valves and that one would not set up right. Ran it to 0 lash and went 5/8 turn past that and it still felt spongy. I pulled the rocker off and I could push the push rod down into the lifter with ease. So I pulled the intake and removed that set of lifters. With 1 finger I could push the plunger down. So I went to my machine shop and he ordered me another pair. Have to buy them in pairs because of the dogbone link.
The new set came in and I reinstalled everything and reset the valves and it felt good. Fired it up and within 5 min. it was ticking again. WTF??? So I pull the valve pan and this time its #5 intake lifter on the new pair of lifters tapping like hell. Thought maybe it needed to run a little but it did not pump back up after about 20 min of run time.
Needless to say I was pissed because now I have to pull the intake AGAIN! My machine shop was going to contact COMP and see what is going on?? He ordered me a new set free of charge and said he will deal will comp on my behalf. He said he buys TONS of comp products and has only seen very few problems over the years. Just my luck I guess!!! Those solid roller lifters are looking better all the time!!! Anyone else hear anything bad about the Comp hydraulic roller lifters for our Cleveland's??
