Had an engine expire due to low oil pressure, but on that occasion we took the precaution of having it followed with a recovery truck due to it being a first proper road run. Then discovered the low oil warning lamp had been removed from the vehicle dash...
Also had a coolant hose split, fortunately not far from a show site. Cooled down, repaired filled and bled up the system. Also had brake pad, handbrake, brake cylinder, coil and road wheel issues but on show sites. Also had an HT lead ceramic end crack.
