A bit smokey

Hi all,

Over the past couple of days i have noticed that my GU is quite smokey in comparison to others in town.
I was looking under the bonnet today and noticed what appears to be leaky injection pipe
(see attachment).

Would this cause the excess smoke or is there something darker lurking that will bite me in the @rse.

If the injector line has a leak, the pressure will be lower, the injector won't be atomising the fuel as it should, so, you will have poor combustion in that cylinder.
Poor combustion can cause white smoke !!!

Thanks ferret, will have a look this arvo.
