I saw somewhere that Ceramic lifters are being manufactured for flat tappets camshafts, and very hard wearing?

Do not know of anyone doing it for the FE, but Jake Raby at Raby's Aircooled Technology RAT uses ceramic lifters in some of his engines. They are said to be reusable on a new cam. Expensive at about 500 for a set (8).
Seems that several companies are now laser drilling an oiling hole in the lifters face on flat tappets. Crower and I believe Isky offer this option.
IMHO, the chance of a flat tappet cam break-in failure is at least as great as the possibility of a roller lifter failure, with similar implications.
As long as the Valve Covers come off easily, the solid lifter adjustment is less than an hour, so it is not a great big deal. |
