on the way home from the CVWOC jamboree today, the van was running rough and seemed to be missing on at least one cylinder. Lack of power and smoke (white/blue) billowing out the back made me pull over and I was then towed home when the AA decided it wasn't just an injector playing up and was something more serious...
The engine is an AAZ with about 100K on it out of a Golf, fitted about three moths ago...typical, really

Blown head gasket (probably between cylinders)
Holed piston
Broken piston ring(s)
Dropped valve
Timing belt slipped
Experience tells me it'll be the most expensive cause, whatever it is

Any thoughts will be much appreciated...
