Valve bearing accepted with catch (3-6)
I believe the answer is:
air-intake
'valve' is the definition.
(I've seen this before)
'bearing accepted with catch' is the wordplay.
I cannot quite understand how this works, but
'bearing' could be 'air' (both can mean an attitude or pose) and 'air' is located in the answer.
'accepted' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
'catch' could be 'take' (I've seen this before) and 'take' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for air-intake that I've seen before include "Engine valve" , "part of carburettor" .)
