I have my 310 German Diesel tore down due to having spun a rod bearing. When I drained the oil I noticed some antifreeze in the oil. It was green antifreeze, not clear water. There was about 1/2 cup or a bit more antifreeze. After a week of thinking about it, I figured it was a cavitation issue with a sleeve, I then prepared myself (and my wallet) for a full teardown and overhaul. I now have the engine tore down right to the bare block, however the sleeves are still in the block. I filled the water jacket full of antifreeze 2 days ago and placed clean cardboard on the floor under the block which is on the engine stand. After 2 days, there is no antifreeze on the cardboard. I am wondering where else the antifreeze could have entered the oil at? or is the reason for no leakage due to the system not being pressurized?
I am wondering what I should do now. Should I still remove and replace the sleeves being that I have it tore down? or should I leave the sleeves in and look elsewhere for the point of antifreeze entry into the oil. Where else should I be looking for leakage? Can this happen in the head? I understand the engine oil cooler can cause this as well. Any other places that I should be looking at closer??
Thanks for any help that you may be able to offer.
