Engine year 2009 fitted in Cranchi Zaffiro 36, private use only. Starboard engine has just been extensively stripped, injectors checked/cleaned etc by spe******t co. All other coolers etc refurbed. New exhaust elbow fitted, head gaskets etc. It appears that even with a slight wash/swell in the harbour our mechanic thinks there is evidence that water ingress is occurring when the engine is not running. Has anybody else had this problem and any ideas for resolving it?
