Heading to the dyno

Comp lifters scare me w/big springs and heavy loads. Mine are coming out for sure now,this is happening way too often .

It looks like the roller bearing just stopped rolling. Everything was cleaned very well with brake cleaner when they came out of the box and the lifters soaked in oil for 5 days before assembly .

Yea,it's happening a lot it seems. Mine are new,but they are coming out for sure,it's not worth losing good parts because of a weak part that can be avoided. I hate that for you.

that just sucks! was looking forward to seeing your results.

agree if it weren't for bad luck... ide have no luck at all.

Man that's a total bummer!!

I sleep MUCH better knowing my engine no longer has needle bearing lifters in it

Real sorry to hear about your misfortune

Sorry to hear. I hope the damage not too bad and can get it back together soon. I agree like the bushed lifters better. I hear all the cautionary tails from the Moral camp, but have heard a lot of good luck from guys that have used the Isky EZ rollers for a good number of years now. For an engine like yours IMO be a good investment.

A short clip of it running

Wont let me open the link, says its been renamed or moved by owner.

I Never like to hear this, hopefully minimal damage and the reassembly will net you more than you were expecting on the next dyno pull.

I plan on firing up my 545 on tuesday for the first time. It has new Comp roller lifters in it too. Something else to worry about now.

I hope your damage was minimal.

Sorry to hear of the failure. Our thoughts are with you.

This is uber lame to hear...sorry.


How was the lash when you checked it after warm up? Did everything seem normal?

Everything seemed fine at the time. The only thing I can think of is maybe the tie bar hole was not drilled exactly center. It ground a flat spot in the roller before the lifter broke. But what's weird is nothing shows signs of heat. Not even the lifter. That broke. the pushrod looks brand also. I would think that if my lash was way off I'd hear it or at least see a little excessive wear on the pushrod tip?

Post some pictures when you do the tear down.
Others may have insight into the issues when pics are posted.

I am sure you will get it sorted.

what p# were the roller lifters?

You did that OK ... DO NOT use Non-Chlorinated Brake Clean, any type chlorinated solvent, toluene. acetone or keytone cleaners on any internal engine parts unless you soak them immediately at least a full day in oil before assembly; no matter what the brand.

On a new set of roller lifters I spend a LOT of time getting the assembly grease cleaned out of the roller bearings. I use mineral spirits in a can, soak them for a while, blow them out with an air hose and repeat over and over until no more grease comes out. Then I soak them in 10W-30 oil for an hour or so before putting them in the engine. Grease tends to not melt and or blend into the oil but instead it can stay inside of the roller and keep oil from getting to the bearing. I think that this can cause damage to the lifter and cause it to eventually fail. Maybe something like this happened.

This is my method also.............. So far so good. I have the 836-16 lifters in most of the engines I do. I have some with the Isky and Morels in them.

I have yet to have a failure.

I have had one go through valve float and pull them to check and they were spread at the axle. This was for one pass with a new cam.

I dressed the sides and replaced the springs reassembled and it is still running.

how long did you prime the engine with a drill on the dyno before you started it for the first time? and what was the oil presser?

I had the same thing happen when I build my engine with the custom cam and comp. lifters. Sent them back to comp. and they said the tie bar is what broke. Happy to say they sent me a new cam and replaced the lifters and tie bar for no charge. Been in 2 years now but are going to be replaced this winter. Sorry to hear about the bad luck.
