Question: If Water was in the Oil, would the Water or the oil come out First when Drained?


( Back )

Answer #1:

Same Time, as Water Oil.

Answer #2:

If the head cracked, water leaked into the top of the cylinders on top of the pistons. Once your drain the oil and repair everything and put it back together, run it and change the oil after you feel it has flushed it, you should never have any milky oil again. You only need to change the oil once. If you are still getting milky oil, you still have the same problem. Besides a cracked head, you may also have a cracked block.
Putting warm water in a hot engine does not keep you from cracking the block or a head. Before ever adding water to an engine that has gotten hot, you need to let it cool down for an hour or so until it is below 100 degrees at least. When a motor runs out of water and gets hot, it can be up around 250 degrees. Even if you put warm water in it, the most you might get out of your kitchen tap would be around 140, you can still crack the block. Sounds like you need to pull the engine and replace it and start over. Getting it to hot, you can burn up the rings and do all kinds of internal damage that you may not have found yet. You have learned a very costly lesson the hard way.

Answer #3:

First things first - when the drain plug is removed, the water will drain first, followed by the "milkshake" and finally the oil.
There are simply too many reasons why the vehicle didn't immediately start after the head gasket was installed to try and address this part of the question. The bottom line is, does it start properly now?
As far as the charging system, you can easily check this with a simple voltmeter - the battery should read 13.8-14.2 volts with the engine running at 1200-1500 rpms. If it does, the charging system is operating correctly.
And any residue that's left from the coolant in the crankcase will be completely gone after the engine is heated up to temperature a few times and the oil and filter is changed.
