Sorry for the late reply. No oil in the water or water in the sump but the level is dropping in the bottle at the rate of about a full bottle in a week. Even after a hard drive on LPG or petrol there's still steam from the exhaust too. Not as much as after just starting when it's warming up but it's there. Can't find any obvious leaks and the HBV was done recently too. Need to get a sniff test done on the coolant bottle. See if there's any exhaust gas in it.
If it hasn't gone though, it's a leak and I'll just keep on top of that until it becomes more obvious where it's coming from.
Back to lowering! After some 2.2 Sport or possible MV6 rear springs (if they're for the same axle weight) to drop the back 15mm. Does anyone have any going spare or know of somewhere that sells them? I don't trust my local dealer after last time and having done some ringing round, can't find any either.

Will be ordering 30mm Weitec springs for the front and keeping with the standard shocks for now. Will replace them with KW ones when they go in the future.
