All right, if you want me to be serious, all BMC 1.5 engines are like that (I have one myself). Before I lived on the boat I started the engine one January when it was -7 celsius and it hadn't been run for two months and a passing Soviet spy satellite reported that Warwickshire had disappeared.
Have not been to the boat for a few weeks so swung down there yesterday to give the engine a run and have a general check around. All ok and the awful rain has been kept out side the boat! Engine start was a bit smokey (well very). Took about 4 goes on the preheat to get the engine actually running. Prior to that it immediately fired after preheat and tried to run but would not respond to the throttle and died. Each attempted start gave clouds of white smoke and once started the engine smoked for a minute to two (and was a bit lumpy) before settling down to pretty smooth and smoke free (or close to) running. Oil pressure is fine 60 when cold and at fast tickover. When hot engine at tickover is around 40 which climb to around 60 at running revs. I'm told all is ok but I just do not like the early white smoke which is unburned diesel I am advised. Thoughts please?
Given that the engine hadn't run during the past weeks of damp soggy weather, and that yesterday was fairly cold as well, I wouldn't worry at all unless this reluctance to start and the white smoke turns into a regular performance at every start-up.
The BMC 1.5 is especially prone to doing exactly what yours did yesterday because of the combustion chamber design - the indirect injection Ricardo Comet Mk. V - which uses the CAV 'Pintaux' type Injector nozzles with an auxiliary spray hole which only operates at cranking rpm in order to assist cold starting. The great bugbear of that type of injector nozzle is that they only work as intended for a relatively short time (in terms of running hours in relation to frequency of hot or cold starts) before the auxiliary spray hole gets blocked up with carbon - which results in reluctant starting from cold and lots of white smoke immediately after it does finally light up !
There could have been other factors involved too - for instance, slightly sticky valves closing onto valve seats with specks of carbon on them that had been loosened from the insides of the exhaust ports in the head by damp air blowing into the exhaust system for several weeks. As said at thr beginning, . . don't worry, or undertake any remedial work on the engine, unless and until it becomes a consistent problem when the engine's in regular use.
loddon: Thanks for the confirmation, I am thinking of changing tablets because of the cough but maybe I wont

JohnV: There are other drugs but I haven't found the side effects with Ramipril to be bad, it seems to just make my throat a bit more sensitive so things that might have just tickled my throat and make me want to clear it now make me cough.

loddon: The cough is the only one I get from ramipril, although the combinatins of drugs I am on has interesting effects.
