Remove your afm, block it with something with a port in it to blow air into then listen for leaks. You can blow cigarette smoke in there and look for smoke leaks.

Spray some aerostart around where you think its leaking will find you the general area where its leaking

Some guy on youtube also uses this method but he said try do it with a cool motor to reduce the chance of combustion under the bonnet. He also said that butane gas in a torch works better and is generally safer...

Id use aerostart as its designed to go into engines and has anti-knock additives from memory. that's just me but

How do they do this? Suck smoke through the intake and see where it pops out or blow smoke around parts of the engine?

Ok that sounds awesome I might give them a call how much did that cost

on a 26, one of afm intake pipe is blocked, the other has a bung with nipple attached fitted and smoke is pumped thru on low pressure, costs $25 from memory

it will pick up leaks on vacuum hoses etc but not internal leak like bov seals etc, anyways they will explain better
