Disco 2 Bluish haze on start up

Ian Mackay · Feb 21, 2018

Something is not right over the last few weeks there seems to be a fair bit of light haze on startup then clears but this morning the haze drifted like a cloud, as far away as about 20 feet and lingered, I drove to work and for the first mile I could see smoke / steam or whatever, when I got to work (15 miles) it was perfectly clear, thinking all sorts is it the turbo, bores, injectors, bought oil and filters for a change just in case then I noticed the coolant level was quite low, seem to remember topping it up quite recently, ......... only other thing I have changed recently is the fuel cooler, can there be a crossing over of water to fuel, ...or is it head gasket time, how will I know...:-(

And this morning Nothing, I wonder if it was water in the fuel, will drain filter to check tonight, fingers crossed.

Water/coolant will be a white smoke ( it is steam after all), a blue smoke is oil, if its diesel it will be a greyblueish colour and will linger about. Its quite acrid too if you can get a sniff of it. A bottle of injector cleaner wouldn't go amiss anyway

Summing it up recon I have a small leak into one cylinder overnight, a bit knocking to start, the hoses are not pressured, buying top end kit next week, and possibly getting the head skimmed, fan belt needs done as well.

Well that is the easy part, a 5 minute job max...just make sure to buy the right one.. Good luck with the others stuff.

Cheers

Thanks, head gaskets not a big job, I'm lead to believe
