I didn't realise it was such an issue on mine until I first changed my spark plugs when I first got it
Completely rusted in and according to the service book they had been changed 14 months previously
The previous owner has done 12K miles in a year though
These are my do's as I've yet to fit my new cam cover and spark plug cover
1. John Taylor storm cover on every time it's parked outside and rain is forecast or if parked for a while
2. Always cover the engine with plastic sheeting when washing the car- no matter how careful with water on the bonnet (make sure engine is cold of course to avoid melted plastic)
Haven't tried it but would putting grease or vasiline around the spark plugs help or is that a no no ?
