Water in oil D4/ D315 engine

have you checked the coolant to see if oil has pushed it's way into the cooling system?? I would have thought that the oil would go milky with coolant in it.

I would personally drain the oil and put to the side. go buy 15-20 litres and refill. run again and see if your oil get contaminated right away. (at approx $40.00 for 20 litres,it is a cheap check).

if you oil does get contaminated again, then you know you have another leak somewhere else...

good luck

Does the D315 engine have a gear driven water pump? I had the shaft seal on my 3304 engine go bad between the water pump side and the gear (oil) side. The coolant was pushed/drained into the oil pan. The engine did a nice job of mixing the mess into chocolate milk.

Did you start out with new oil? or at least drain the water/condensate off the bottom before starting it up?

Thanks for the replies.

There is no oil in the coolant, and the pump is driven by the fan belt and crankshaft pulley. And as far as draining the oil first,no. I thought that I would run it to operating temp, and then shut down and do a complete oil change with new filter, and oil. In hind site,I guess I should have at least drained some off first to check for water content in pan. I am not a mechanic, and have never worked on diesels before, let alone ones that have sat for awhile. All that I have learned came from reading manuals and what infomation that I have read from here. But I do love old cats.

OK, just thought I'd ask before going in to the long list of candidate sources of water leakage. Probably nothing wrong once you get converted to new oil and get the old crud flushed.

In the future you should check/drain off all compartments before starting a resting Cat.

Change that to ANY machine that has oil in it and rested for a long time.
