: My B engine sounds like a well oiled sewing machine because the valves and lifters clatter a little, but maybe that's a good noise according to other opinions.One of my Model A parts books shows the double lock adjustable valve tappets, but says, "for easy adjustment, adjust these with valve springs and timing gear removed".I really don't want to tear the engine down that far to install these.Any advice?
Adjustable tappets eliminate the removal of the valve to adjust clearances.The adjustable tappet is very adequate and should be adjusted as in a somewhat more modern engine with the valve springs and other valve components "loading" the camshaft.Sometimes with the use of a reground camshaft, the lifter isn't raised enough to allow access to the adjusting nuts.A remedy for this is to machine down the tappet bosses a bit.This involves engine disassembly.
The installation of these tappets is a good fix for valve adjustment at regrinding and has been around for years.If I may be of more help, let me know.
