Agreed, not a great start to the week. It took 4 hours from calling the rescue service to the low loader arriving. In that time i could have walked back to Farnham, gone over wiht my own trailer and still had one hour to spare. The cause was the crank pulley coming loose. The real problem, unfortunately, is that I did not notice the lack of oil pressure soon enough so the engine will need a complete strip down to check on the extent of damage. ☹️
