Stupid question time

[the ferret]

So in conversations with the cylinder head blokes, owner of mechanics and floor manager at mechanics in regards to my cylinder head, we have spoken about "Tappets" "Buckets" and "Lifters"

My question is : are these all the same thing? Or are they different components.

Cheers.

Not such a stupid question mate, you are asking because you don't know, now you will know.
Generally The tappet is the name given to the clearance between the top of the valve in the head "noisy tappets" and the underside of the rocker arm.
Buckets, I can only asume they mean the seals on the valves inside the valve spring, these help to prevent blow by from the cylinder.
Lifters are the things that follow the lumps on the camshaft and in turn, raise and lower the inlet and exhaust valves to coincide with the compression,combustion, exhaust and intake cycles of a 4 stroke engine, be it petrol or diesel.
Hope this helps you to understand what they are rabbiting on about, just say ""MMMMM" and nod from time to time.
Cheers, the ferret.
