I've been working on a d4 d-4400 engine that sat under a tree for a while and had the frost plugs rust through allowing a large quantity of water to get into the oil. This is easily checked by removing the rocker cover. You said oil in the exhaust sounds more like precombustion chamber seals or a bad head gasket. Hopefully not the worst possibility of a cracked head/block. What model d4 are you working on?

[quote="Cattle237"]So how much trouble am I in. Put water in radiator and went to start engine water came out exhaust and now about a gallon in oil pan. This on a old D4 Cat. Any advice would be welcome. Also need to find wrench to remove oil pan plug.
Thanks Barry[/quote]
No wrench needed; find a bolt head that fits the plug and weld a nut onto your bolt. Viola, instant oil plug tool. Doubles as a final drive plug tool.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
