So i had the same issue. Noticed oil leak on my belly pand and it tracked to oil filter housing. I thought it was oil filter cap O-ring which was not. Then replaced oil cooling hoses O-rings, still leaked. It ended up being a crack in oil filter housing above oil cooling ports. It only leaked on cold start. I had to replace the oil filter housing which is pain in a a$$. You will have to remove pretty much everything from the front inculding radiatior and much more. So just make sure you do a right inspection and O-rings before anything else.
