White smoke from the engine
Hello,
When I start my car with the engine cold, a white smoke is seen around the engine, for about 2-5 seconds, then it dissappears. It can be seen only when the engine is cold and it has a strange smell.
What can it be?
Thanks.

Re: White smoke from the engine
Where is the smoke coming from? Is it from the Engine Fusebox behind the battery?

Re: White smoke from the engine
Possibly a leaky injector - they have a habit of coming loose on the 1.6.
Look for signs of a coal-like substance around the base of the injectors.
The brackets holding the injectors are said to be easily damaged. The torque for the bolts is crucial as it is easy to shear them.
I believe new bolts are required each time, not just re-tightening the fitted ones.
Someone correct this if it is inaccurate.

I can’t see exactly, it just pops out all around the engine I guessGiveMeABreak wrote: ↑30 Nov 2020, 11:33 Where is the smoke coming from? Is it from the Engine Fusebox behind the battery?

Re: White smoke from the engine
No - if it is these that have come loose, just get them tightened to the correct torque.

Re: White smoke from the engine
Not usually. The brackets and bolts should be renewed as they break easily, also, depending on the severity of the leak, the seals and fire washers could need replacing, and the injector(s) seat(s) need cleaning - there is a special tool for this.
The problem with them is that if allowed to continue it can lead to more and potentially very expensive faults, one being a destroyed turbo.
If you have a look for similar faults on the forum, there are many tales of woe surrounding the 1.6 HDi if it is not well looked after and service intervals ignored.
Looked after it is a decent engine, don't be put off by the above.

Re: White smoke from the engine
Check if it loses coolant, it is possible that a little leaking antifreeze from the back of the engine goes to the exhaust pipe, as you start the engine the antifreeze evaporates in the form of white smoke. White smoke can also be from burning oil.

Re: White smoke from the engine
That was my first thought. When ethylene glycol is heated, it produces clouds of white fog. It is the basis of stage smoke! Our first BX produced whole streetfuls from the tailpipe under acceleration when the head gasket was on the way out. It usually has a characteristic sweet smell.petarc1971 wrote: ↑30 Nov 2020, 14:35 Check if it loses coolant, it is possible that a little leaking antifreeze from the back of the engine goes to the exhaust pipe, as you start the engine the antifreeze evaporates in the form of white smoke.

Re: White smoke from the engine
Yes, I have coolant loses, but I thought it was from the cylinder head gasket.petarc1971 wrote: ↑30 Nov 2020, 14:35 Check if it loses coolant, it is possible that a little leaking antifreeze from the back of the engine goes to the exhaust pipe, as you start the engine the antifreeze evaporates in the form of white smoke.

Re: White smoke from the engine
Could the leak be coming from a weak or loose hose clip on the cabin heater side of the system, could be something simple

Re: White smoke from the engine
Given that the symptoms are only stated to be present with a cold engine, I would not think it likely to be related to a coolant leak, as coolant doesn't produce white smoke until you heat it up.

Re: White smoke from the engine
Yep, but still, there is a problem with the coolant too. I’ve changed the oil cooler, because I had oil into the coolant, but I can still see pressure into the coolant sistem, because I loose coolant at the coolant lid. I hope this is not a cylinder head gasket problem (I don-t have coolant into oil, I just had oil into coolant). A lot of problems with my C5, but I hope I’ll fix them...

Re: White smoke from the engine
Over-filling the coolant (presumably at the expansion tank) will lead to coolant being expelled every time the engine gets up to working temperature. There should be an air gap above the coolant there, to allow for expansion. Check out the level.
