It may be that the deep cold has shrunk some of the o-rings and is letting in a bit of air. If leakage is suspected, re-orient the nose of the car downhill, the steeper the better. Not easy if it doesn't run, I know.
Either way, if they aren't relatively new, replace them all with Viton o-rings.
Hi Alan,
How many O rings are there and where are they?
Also the behavior described in the OP is exactly how mine runs when a glow plug fails, very lumpy and lots of white smoke. One failed at the weekend so I have that joy to face this week. It's like Russian roulette, will it come out or snap
