Changed the oil at the weekend and spilt some so while I was cleaning it off I decided to gently spray the rest of the engine with a very fine hose to clean it up. I took it out after this and it ran fine for a blat up the motorway, but the next day it started fine then began to misfire which got worse until it cut out. It started a couple of hours later and also tonight for a few minutes then it did the same and it wont start again. Also there is white smoke coming from the exhaust pipe so I assume there is water somewhere. What do I do now any help appreciated.
p.s. my inner voice was telling me not to try and clean it perhaps I'll listen in future
