Crew provided obsolete engine part, for example (8)
I believe the answer is:
manifold
'engine part for example' is the definition.
(manifold is a part of a car engine)
'crew provided obsolete' is the wordplay.
'crew' becomes 'man' (I've seen this in other clues).
'provided' becomes 'if'.
'obsolete' becomes 'old' (I've seen this before).
'man'+'if'+'old'='MANIFOLD'
(Other definitions for manifold that I've seen before include "having many features" , "Many and various" , "maths set" , "Abundant" , "performing several functions" .)
