Make issue for energy-guzzling old banger (9)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
procreate
'make' is the definition.
(procreating is a kind of making)
'for energy-guzzling old banger' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'energy' becomes 'e' (physics symbol as in E=mc2).
'guzzling' is an insertion indicator.
'old banger' becomes 'crate' (I've seen this before).
'e' placed inside 'crate' is 'create'.
'pro'+'create'='PROCREATE'
'issue' is the link.
(Other definitions for procreate that I've seen before include "To be a breeder" , "Make children" , "father" , "Get children" , "Produce offspring" .)
