Mondeo TDCI white smoke

    Hi,

    I have a 08 Mondeo TDCI

    When I start the car there is no white smoke.

    When it warms up it starts

    Yesterday there was loads and loads of white smoke and I used a Head Gasket sealant and this seems to have reduced the smoke.

    I can see it draining the coolant very quickly but I can see it leaking anywhere on the ground It also runs very rough like a misfire?

    Any help would be great.

    Sounds like a head gasket leak. There would be no coolant on the ground because its leaking internally into the cylinders hence the white smoke.

    How quickly is the coolant draining? As in how many times do you need to top it up?

    Have you taken it to a garage yet? They can diagnose for sure if its head gasket but it sounds likely that it is.

    Either it's elected a new pope, or it's trying to burn coolant. I think the latter, hence a failed head-gasket.

    Put this in

    I had a mechanic look at it and he said the stuff I put in fixed it but I didn't leave it running long enough to allow all the white smoke to leave the engine.

    No smoke and it seems to be running fine.
