Water in the Oil: 1930 Packard 7-40 Super 8

Posted by Rich1028 On 2022/1/5 14:52:55

Going through making progress in rehab'ing a lot in the engine compartment...new head/exhaust gaskets, carb, etc.

The latest: I drained the oil and it looks as if I have water (antifreeze) mixed in with the oil. When drained into a pan, there is major separation with a layer of oil on top and a greenish sludge on the bottom. It does not resemble clean or dirty oil at at.

So my questions and areas where I need assistance:

-Where other than the head gasket can the antifreeze be mixing with the oil?

-I've removed, cleaned and inspected the head and it looks good...no cracks, no issues.

-I am changing the head gasket.

-If the block has a crack, where do I need to look for the crack...ie, are there places on the Super 8 engine that are prone to cracks?

-Where else, what parts of the car do i need to look at for why/how this water is getting into the engine oil.

-When I get home I will post a few photos that I took of the oil/sludge mixture.

I am hoping, so much, that this is some kind of one-off and water somehow got in here through a bad gasket or something else. Pending finding any cracks, I am going to reassemble, fill the oil, run it for a while and see if the oil remains clean or is starting to mix again with water.

Any help, suggestions or recommendations with your experiences would be greatly appreciated.

Thanks,
Rich
