I wasn't doing the change myself, i thought £20 that local garage charges for it is reasonable for not having to spend 2h on doing it myself. so i bought the oil and filters from local dealer and left almost 7l of oil and filter with them. I normally watch them do it, but today i couldn't and i think they've used all 7l (they claim it was ok on the dip stick), but i'm hoping it's something less serious. But everything seems to point to hydrolock caused by too much oil - engine started fine, then stopped with a bang, and would not turn over, after some time (presumably letting oil drain back into the sump) engine started again with a lot of white smoke and stopped with exactly same bang after few seconds.
Anyways i now have Nick in Norwich looking at it
