Massive oil leak with video for diagnostics (95 Oddy)

Hi,

My 95 Oddyssey starts to leak oil from close to oil filter mount after an extended stay (3 weeks in cold winter). It only happens when engine is running. I replaced the filter, but with no difference.
I taped the action in the following link, any suggestion is appreciated:

Thank you!

Just an update. It was the oil cooler seal that was leaking. paid $10 including shipping from parksgeek and now it is fixed.
