Problem with van

[La Poste]

Brake fluid gets into the inlet manifold via the vacuum pipe that leads from the vacuum drum/brake servo , the big round thing underneath the brake master cylinder.

I can see the logic with this, on my old Peugeot 306 DTurbo the vacuum caused by air being pulled into the inlet manifold is used to suck air out of the brake vacuum drum/servo. If the master cylinder is leaking then brake fluid will leak into this vacuum drum/servo, this fluid will be pulled through the pipe that connects the vacuum drum/servo to the inlet manifold and the fluid will then enter the diesel combustion chamber and be burnt along with the diesel fuel, it is quite possible for this to happen is you have a brake servo connected by a pipe to your inlet manifold.

My Peugeot has an EGR valve but I took it off as it is unreliable, I cannot see how a faulty EGR would produce white smoke, it might do if the engine is cold but not if the engine is warm, well in my opinion anyway a faulty EGR would not produce white smoke if the engine is warmed up and operating at normal temperature.

The vacuum pump that creates the vacuum for the brake servo, is it connected to the inlet manifold or is it a standalone pump that has no physical connection to the inlet manifold?

Solving problems with cars or vans is like solving electrical problems, you need the right test equipment otherwise it's guess work.

if a Turbo went it would be black smoke as the Turbo is lubricated itself by the engine oil

Or blue smoke when the seals go...

To clear things up here's a little guide...

The vacuum pumps dump the air which they've pulled in under vacuum into the crankcase, remember this only happens when the valve in the back of the servo is opened letting atmosphere pressure in, now there's a slight chance of fluid being in the servo due to leaking master cylinder, now I can see how ths can find its way through the vac pump and into the crankcase, if oil level sumps too high it can be pushed up the breather system and into the induction but remember the brake fluid resivoir will hold less that a liter of fluid, the light comes on when ths level drops slightly, so I can see how you'd ever get enough brake fluid to over fill the sump enough for this.
Unless you stand there pouring it in?

Diesels do not normally create enough vacuum at the inlet manifold to operate a brake servo that is why they use a vacuum pump. There would be no vacuum on the inlet manifold of a turbo diesel as the turbo creates a positive pressure in the inlet manifold, on turbo vehicles I've only ever seen brake fluid dumped into the engine oil by a vacuum pump

The vacuum pump that creates the vacuum for the brake servo, is it connected to the inlet manifold or is it a standalone pump that has no physical connection to the inlet manifold?

All the pumps I've seen are standalone driven by the camshaft

So that rules out brake fluid then, it must be water or unburnt fuel.

Maybe it's washer fluid?

maybe to many chips in the oil.

backs of vans are far more interesting than whats in the front i think... x

I was being sarcastic when I wrote this but then I remembered years ago working on a mk4 escort, it was a rs turbo, there was a small pipe coming out of the washer bottle, through a actuator and into the induction (before turbo) looked into it, was a boy racer bolt on, the idea was that injecting a fine mist of water into the induction makes the air denser, allowing more fuel to be burnt, would have liked to see it if they got it wrong - bent rods!
Personally a thought the whole thing was a load of rubbish.

Unless it's a six stroke engine...

As per a post on the 1st page of the thread. We'll get there in the end lol

Thank you amp David, some one that agrees,

Thank you amp David, some one that agrees,

Had the same car, and got rid when similar things started happening.

makes no sense to me.... boys and toys..

Vans and cars are essential pieces of equipment, they are not toys.

Learning to fix your own vehicle can save you absolutely thousands of pounds, I would say teaching yourself how they work is a very good investment and also a very sensible thing to do.

Labour charges at £100 per hour and spare parts marked up so the garages make even more money out of you, imagine what else you could spend that money on.
