From Brendon - Plonky in the naughty corner at Ardmore waiting to go in the hangar. For those who have been asking, at some stage in the flight the aluminium cylinder head of the bottom front cylinder has slightly separated from the steel barrel by a few millimetres which moved the pushrod oil tubes out of their seals enough for them to leak and create a mess. There was no change in engine performance during the flight so no warning.

Yes. I once had a student go for an aerobatic practice sortie, and make a hasty return to Ardmore when an oil film started to cover the windscreen. He had neglected to secure the oil dipstick cap when he checked it during his preflight inspection - not great at the best of times but particularly so when you're going to be upside down! Needless to say only about a litre of oil was lost but it took all afternoon to clean the insides of the cowling and the engine block and accessories.
