For want of a better word tappet rattle, its not a big concern thats for sure but anything to make our engines quieter is a plus, John Roberts new cam follower I'm sure will be a blessing for many.
I had and I'm sure others as well have developed their own "fix" , and some would suggest just put up with the klatter, well everyone is entitled to their own opinion.
I had developed my own "fix" and now after some testing will be making my remedy available to the masses.
It may appear a simple "fix" but much effort has gone in to this development to perfect it.
IF you think by sqeezing in a spring between lifter and pushrod will do the trick then go ahead, without modifying the lifter damage to your engine is guaranteed.
Modification to pushrods and lifters is required apart from the specially made spring.
I considered an exchange basis of lifters and pushrods but I expect people would be sending me junk lifters and pushrods and expecting new ones in return, so it would be a case of me modifying your parts.
Now, for the effectiveness of this mod, you can do your own test now,
(1) start your engine and listen specifically for tappet/camfollower rattle, even using the screwdriver in ear
method at your cam follower tunnel and tappet covers.
(2) stop your engine, adjust your tappets to zero clearance and restart the engine and again check
noise level.
this is how your engine will sound with the modification.
Of course this is only practical on engine rebuilds , or have a set modified ready for the next rebuild.
Cost ? send me your lifters and push rods and for $100 I'll Fedex them back to you modified and ready to fit.
