Change of cam in engine with Schubeck lifters

[Speed-demon]

I am considering to change my can drom FK 10 to FK 87 or FK 89. My engine currently runs with Schubeck ceramic lifters. Do I need a new (extremely expensive) set of lifters with the new cam, or can I run the lifters I already have?

I have heard that the Schubeck lifters do not need to break in, which tells me that I can use my old lifters with a new cam.

Does anyone know??

Thanks in advance.

No thats what you payed that money for,just put the new cam in and your good to go

I'll trade you for some new Scat Lube-Your-Hole's. 

Everything I've read suggests you can reuse Shubecks on any cam you choose over and over. They never wear out.

[Speed-demon]

No thanks I have tried them Scat lifters, and they pitted.... So I'll stay with the Schubecks. 

Any special advise in running ceramic lifters? Thall I use "break in" grease with the Schubecks and the new cam?

You dont have to bed them in either,unlike a normal Cam/lifter break in with Shubecks you just fire it up and are good to go

if you are just changing cams then a little lube to help till it gets oil pressure,but it should be imersed in oil, if the level in the motor is correct.

I'd use moly disulphide (arp lubricant you get with arp bolts) It just sticks on the lifter better. You shouldn't worry about the schubeks. I just hope you have silicon/bronze lifter bores.

I do not know whether or not I have silicon/bronxe lifter bores. The engine is built by Udo Becker, so I better contct him to find out. Why do I need such lifter bores with ceramic lifters (out of curiosity)

Because of wear. In mag cases there has been cases where the bores was oval after very few miles. I did not know that the ceramic lifters was more agressive against the bores than other lifters and thought this had more to do with cam profiles and pressure.

Alan - you had a bad experience with the FK47 in a mag case if I`m not mistaken? Please share your experience with us if you feel like it. Personally I`m interested in knowing if this is likely to happen with alu cases as well.

 Are those Ceramic lifters any good? I mean, if they break (or rather shatter) those tiny ceramic grains get dragged along with the oilflow scratching every singe part in the engine.
 Great things, but I wouldn't want to experience a failure of one of those... 

 (then again if a rodbolt fails it could do serious damage as well)

Must we bring up bad experiences 

I highly suggest silicon/bronze sleeves due to lubricating properties of the material. The sideload of a rampy fk40 series cam with stiff valve spring pressure is a very potential chance of lifter bore wobble. With a ceramic lifter your in real deep poop!!! My udo becker tool steels took a serious beating and I reused the lifter for an fk46 in a different case (sleeved). Mind you I'm using a mag case not an aluminum t1 case.

Aluminum is still not as good as silicon bronze. For example Rimco will sleeve a mag case with aluminum. IMO why spend money on aluminum sleeves when you can use a far superior material like silicon/bronze.

If I had an aluminum case I would use it till it needs sleeves. BUT in a mag case I will NOT EVER use a fresh virgin mag case without sleeving it. I've been bitten twice with severely wobbled lifter bores and getting caught with your pants down twice is simply stupid in my part.

I think Udo mentioned to me that he always uses sleeved cases.

I think your case has no lifter bushings . What engine do you have ? I never used ceramic lifters
