smoke out of the exhaust

[jj0688]

my ford transit seems to blowing out alot of smoke when i rev the accelarator its not the oil but i dont know what it is?

[bigboots]

If it is white smoke then it is water and most likely head gasket problem
If it is grey then it is unburnt fuel and could be an injector
hope this helps

The old rule of thumb for smoky exhausts went as follows -
White smoke - Water (ie steam) or brake fluid.
Blue smoke - Oil.
Black smoke - Unburnt fuel.

Brake fluid might sound strange but I'm told it can get into the inlet manifold if the brake servo is faulty.

think youll find on a transit 2.5 di that white smoke would indicate unburnt diesel, cant say ive ever came across brake fluid fumes from an exhaust!!!

David, read all of my answer. I said myself it was unusual.
But the info came from a guy who has worked on cars and trucks for 50 years so I reckon he knows a bit about them, eh?

[david1702198]

well i have worked on cars for around 10 years myself and i know h o r s e s h i t e when i see it. no body who has worked on any sort of transport for 50 years woud come out with a stupid answer like that. brake fluid coming out the exhaust!!! they should rename this site to jokerbank

blackthorn you tried to answer yourself but unfortunately you dont have any knowledge do you!! you do what most other folk on this site do - talk a load of s h i t e and guess. brake fluid dripping ONTO the exhaust ill give you but brake fluid fumes coming out of the tailpipe?? unfortunately not my friend

[david1702198]

we will go with your faulty servo theory then, in order for this to happen we will need the seals in the master cylinder to go, the diaphram inside the servo to go and then for the fluid to be leaking to the extent that it would force its way past the vacuum which incidently is coming FROM the inlet manifold/vacuum pump to the servo!!! all the time there NOT being a fault with the brakes or abnormally hard or spongy brake pedal!! 50 years my arse
