Engine Oil (Milky / Gray)
My engine oil recently almost doubled in capacity when i changed the oil the
other day. It is gray / milky looking. Suggestions from another post said have a mechanic look at it becuase it might be a warped head. Is there anything else it could be? Also do you recommend I get it service before the winter? |

Engine Oil (Milky / Gray)
PS: How do they determine where the leak is coming from? Is it trial and
error is it a test with a dye like a car? "Matt" wrote in message ... My engine oil recently almost doubled in capacity when i changed the oil the other day. It is gray / milky looking.

Engine Oil (Milky / Gray)
Last time I saw that mixture, it was in my S10 Blazer's V6. It was a result
of water/antifreeze steaming into the oil. Eventually led to my crank seizing hard one cold Winter night, bearings have no sense of humor. Cost of repairs - new short block assembly, rebuild the heads, and reinstall and test. I'd say your's is a similar problem and you best start stripping down to the basic block and rebuild it. My guess would be warped heads or even a bad head gasket. But these days, I'd end up letting another wrench fix it and I'd go find another vice to keep me occupied. lol! Whatever you do, do it right away. Don't run the engine or you may end up shopping for a new short block assembly for yourself. Murph "Matt" wrote in message ...

Most likely a perforated exhaust riser. If not that, either a blown head
gasket or warped/cracked head. Bad news in any case. "Matt" wrote in message ... My engine oil recently almost doubled in capacity when i changed the oil the other day. It is gray / milky looking.

Those are the classic signs of getting water in the oil. Now the question is where does it come from? Do you have a fresh water cooling system? If so, then if the leak is from the cooling system into the oil then you should also be losing water from the cooling system. A leak from the cooling system into the oil can be from a number of places. The head gasket is a common failure point, but it is generally the secondary effect of "blowing a head gasket", which generally is accompanied by a loss in engine perfomance and overheating. The "warped head" leak is generally the result of a significant overheating experience. Another possibility is that rust/corrosion has created a leak path between the cooling passages and the crankcase. This could be at a gasket, such as the intake manifold or head, or through a casting itself. This is much more likely to occur on a "raw water cooled" system, especially if used in a salt water environment. Is there any possibility that bilge water got high enough to cover the dip stick? I have seen that happen before. My suggestion would be to run a compression check on the cylinders. If you had a bad head gasket, I would expect a problem to show up there. Next if you have fresh water cooling, I would run a pressure test on the cooling system. Above all, you should definately take care of this now, don't wait! You may have a major problem that will require a fair amount of time to resolve, so fix it now so that it doesn't subtract from next season! Rod |

Engine Oil (Milky / Gray)
The most common problem in boats is the exhaust system. The manifolds,
risers, or the gasket between them leak. The water runs down into the cylinders through open values and then leaks past the rings into the oil. How old are your exhaust manifolds and risers? Do you boat in salt or fresh water? Second problem is that people don't drain the water form their engine, it freezes and cracks the block or heads. Did you winterize last year? Did you change the oil during the summer and it was ok then? A warped head is usually the results of severe over heating. Did the engine overheat? It is best to make every effort to figure out what has happened before you start disassembly. It's going to be bad no matter what it is. "Matt" wrote in message ...
