So I'm trying to figure out why my 4kq (NG engine) is still having some hesitation issues. Before I got to what I was trying to do,
I took the big rubber intake boot off to find it dripping with this caramel-y oily stuff.
I'm guessing its coming from the breather hose that goes from the intake boot down to the crankcase.

What could cause this? It wasn't like this a month and a half ago when I last had it apart...

Any ideas?
