Thanks a bunch Tim. With this information i think im gonna bite the bullet and pull the engine out. Ill probably only tear the top end down though. I think its leaking oil externally out of the HG. I could probably blast the block out with a pressure washer without taking the crank shaft and pistons out. This isnt what i intended to do when i bought the van but its gonna be a great learning experience. hopefully it pays off and i have an awesome van in the end haha. Thanks again!! James
