I jumped on the Schubeck lifters as soon as they hit the market. Ran them until last year. I, too, was a big supporter of this style lifter. But, dodged a bullet last year when two of them came apart. And damn if I didn't get talked into buying the Smith lifters and that mistake cost me $10,000.00. No more of that crap for me.

Re: Schubeck lifters
 
I have an old set of Schubeck lifters in one of my engines. They work fine. Then I built another engine and used Smith lifters and on the nInth run I broke two lifters, which caused severe damage to the block and 4 Pistons. From that moment on, Smith lifters was never to be used again. From now on I use tool steel coated lifters. They will not come apart and destroy the engine. I cannot imagine how anyone would take a chance on using a part in their engine that so many people had trouble with. Some people never have trouble with them.

Is it possible to go from shubeck lifters to tool steel coated and still use the same cam.

Re: Schubeck lifters
 
BTW what engines are breaking?

Is there a trend...?
A Chevy, Ford or Chrysler? BB, SB, Medium Block if that exists.
Which Engine seems to be breaking most often?

Do not think this is happening to Roller Lifters?
At least I did not hear of any so far.

If the cam in question is a steel core cam, yes, you can. If the cam in question is a cast iron core cam, do not run DLC coated lifters on it.

Re: Schubeck lifters
 
The answer is I have heard of all brands and sizes of engines sometimes
have problems with Schubeck lifters. I think more problems with solid lifters than hyd. lifters. My hunch is the problem may be with the solid lifter unloaded from any preload while on heel of cam. I alway put a few thou
more preload than normal with Schubecks.

Its been more relaxing this weekend driving a car with roller lifters, I'm not having to worry about idle RPM and oil splash.
