Old car of bishop has incense (6)
I believe the answer is:
banger
'old car' is the definition.
(I've seen this before)
'bishop has incense' is the wordplay.
'bishop' becomes 'B' (abbreviation used in chess).
'has' says to put letters next to each other.
'incense' becomes 'anger' (I've seen this before).
'b'+'anger'='BANGER'
'of' acts as a link.
(Other definitions for banger that I've seen before include "Sausage (informal)" , "Old car (colloq.)" , "It might just drive" , "Noisy old car or slang sausage" , "Decrepit old car" .)
