An odd one. Been going 15 mins at low speed behind 27mph observer!. At 'D' restricted point accelerated past, but nearside rear wheel slewed and spun - thought I had puncture. Managed to get past, and stopped in about 1/2 mile and had shock of seeing oil everywhere, inside and out, and dripping off rear tyre.
Didn't know how much oil loss so got recovered. Having done detailed inspection found that oil filter seal was protruding, and on removal the seal is quite distorted at one point. For whatever reason assume oil loss from that there, but can't understand why. Changed filter about 3k ago, and know it was properly seated, and have had no leaks. Don't know if it's possible to get a pressure build up fo some reason, and it released at point of least resistance?. Have drained what was left of oil, and got about 1/2L out, so am thinking me crank may not be in great shape!.
What should I do now? - fill it up, new filter and start - hoping for the best, or get it taken in for proper check up. Any advice would be much appreciated - not feeling great at the moment!!
