I took another look at the pictures. Assuming the oil sump plate is oriented the way mine is, the leaking is in the area of the #1 cylinder, isn't it?

That's not the triangle of death - though if the #3 or #6 look like that, that's different.

A leak by #1 or 4 could be from a bad cam seal. It could be from one of the chain housing pins for the bits and pieces of the chain and tensioner system getting loose in its hole in the chain housing. It could be from a leak between the chain housing and the mane case. Or from one of the rocker shafts for those cylinders.

I don't think (based mainly on that one picture) that the leaking is from the cylinder base copper gasket. Has anyone found that to be a common issue at that level of leaking? What has been the experience of guys who found they had driven for who knows how long with several broken head studs? And in particular the lowers? Big leaks from the cylinder/spigot seal as combustion tried to lift the head away from the cylinder and thus the cylinder not compressing the seal enough?
