This one is greasy, what can cause this? Oil in combustion chamber? Backfiring???? I was going to guess the EGR would dump above this runner but this runner is furthest one from the throttle body and the EGR dumps right behind the throttle blade. Maybe the particulates from the exhaust collect at the back of the intake manifold and fall down the last runner?

That is from the PCV system. The big hole in the manifold at the #6 runner is where it sucks in from the crank case.
This is the path I'd like to run, but I am concerned the tensioner does not have enough movement left to give the belt nearly enough tenison. Maybe run a bigger pulley?

This could work. The tensioner has a stop on it at the end of it's travel. You could cut that little stop off and the tensioner will turn further. But.... The further it turns, the lighter the spring pressure gets, and there is no stop keeping it from pushing the belt together if it gets slack. I think there's enough room there for it to work though so long as you get the shortest belt you can onto the pulleys.
Another consideration. The tensioner is a sealed unit with the back of the center stud swaged over, but you can get it apart. Once apart, you can clock it by drilling a new hole for the end of the spring to sit in. I did this to mine as an experiment (but went the other direction). This would give the tension needed and I'd even swap to a smaller pulley on it so it won't contact the belt on the other side of the alt so soon either.
