yeah, pretty sure its oil. I spent part of this past week degreasing the underside of the engine to pinpoint the engine leak and it's next to the heads. I can even see enough of the gasket to probable pull it out with some needle nose pliers. Maybe its always been like that but the oil leaks are coming from the same place on the heads, near the #7 and #8 cyclinder.
I don't have the time or money to pull the thing yet, and, as it stands now, if it's going to be pulled, I may as well rebuild the whole damn thing. I'll post pictures whenever I get around to doing it all but that won't be for LONG time. I have a lot of pictures of what I've been up until now, might post those when I get the chance. There's a diesel program at the local tech school where I grew up that I planned on enrolling in at the time but, there wasn't time. They have taken student's engines in and rebuilt the things during the course of the semester. That's the most practical solution for the time being, don't know how realistic it will be, though.
There'll be pictures since my wife is okay with it simply being a hobby van now, so there isn't any rush now. I was in a big push just to see where it was at with the most OBVIOUS and EASIEST problems fixed. Now that the least time consuming stuff is overwith and it is STILL broke, I know anything beyond this is out of the scope of possibilities now.
