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.

So far have heard them called simply valves (from engine course at uni), one mechanic called them tappets (in his 40's or 50's), another called them lifters (in his 30's). Buckets is new to me. So far to me it seems to be put down to what they were taught.
Brother has a similar issue at his work being in a wreckers, they know a part under one name, customer comes asking for the same thing but calls it something else, no idea what the customer actually wants without some discussion.
Not 100% on this so if someone actually 'knows' for certain would be great.
Not such a stupid question mate, you are asking because you don't know, now you will know.Originally Posted by GQ snail
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.

Actually i had a mitsubishi express van years ago unfortunately.
Anyway i had the head fully recoed fitted it up and had lifters not pumping up i was stumped turned out the morons that recoed the head put the rocker assembly back together the wrong way.
What happened was the oil gallery supply for one side was upside down or the wrong way round and it was an absolute pain to find you may have something similar.
worth looking at anyway.

Cheers ferret, that has cleared it all up.
Cheers mate, it's only a basic description, It might not be specific to your engine, but the design of the internal combustion engine hasn't changed much in a hundred years.
The 1927 Ford A had tappets, cam followers (lifters) and valves, even tho they were in the engine block and not in the head.
Cheers, the ferret.
Ferret, I know you have a black belt, 10th dan in Mechology & that you're a Supreme Grand High Master in the Secret Society of Patrolology but your off the mark on what a bucket is. Buckets are those things in the corner of every mechanical shop. After the mech has finished fixing your donk & torques down the last bolt, any spare engine parts left over go in the bucket!
cheers,
PS Has that pretty french nurse managed to escape ferret castle, or you still got her locked up in the tower?
Well, tie my face ta th side of a pig and rooooolll me in the mud.
Ya learn every day, thanks Dingo.
If you send me your email addy, I have a nice pic of an easter bunny, the nurse escaped.
Cheers, the ferret.
A bucket is another type of adjusting setup for your valves instead of having a locknut and adjustable grub screw they have what is call a bucket and shim. The bucket sit over the valve (like an upside down bucket) and the shim sits up inside it when you do a valve adjustment you change the thickness of the shim to get the correct spec. Lifters are what the cam acts on to then push the push rods up and moving the rocker arm. Tappets are generally the bit that acts on top of the valve. They are all different items. Hope this helps
Buckets are usually used on dohc installs where space is limited. You will find them on most late model 4 cylinders. oh my god its got v-tec bro.
