Water in my engine oil. Where could it come from ?
Hi,
Today I removed mx timing gear cover. The inside looks very strange . Its grey and like an emulsion. So I think, there is water from the radiator in my engine oil. Quedtion: Where could it come from ? Thanks Willi |

Could be from a blown head gasket, crack in water jacket.

Also can be condensation build up from cold starts and short drives.

About head gasket: all plugs looks good and looks the same. They would look different with blown head gasket

I will try to close the water in and oulets and then try to blow air in . Maybe I will see or hear, where it leaks.

Do you run straight water? Or anti-freeze mix? If you run anti-freeze mix then I would suspect condensation, as Tom suggested.

Re: Water in my engine oil. Where could it come from ?
Easy things first before you start worrying .. as Tom says in #3 first of all ,
consider other things ..... I'd change oil, and see if it happens again. If it does re-occur take head off and change head gasket see if it happens again, if it does then suspect possible crack etc etc |

If you close the inlet and outlet, how would it affect the radiator? The radiator would be out of the circuit.

Remove the drain plug in the bottom of the oil pan with a catch pan under it. don't drop the plug, just tip it to the side to let the coolant come out slowly until it stops. Coolant will be at the bottom, oil on top. This is a beginning only. and, yes, do not pressurize the radiator.

Re: Water in my engine oil. Where could it come from ?
Hi, of course, I dont presurize the radiator. I removed it. The radiator can not bring coolant into the oil.
I presurized it now, but I didn't find out anything. Condensed water sounds good, but also the other sympthoms made me looking for a leaking in the Jackets or around the valves: 1. Oil level was suddenly higher than expected, higher than maximum. 2. Coolant level in the radiator went down. So I am still confused, Willi |

@katy and 100ih: I dont understand: how can my coolant (wit antifreeze) come into the oil?
Thanks for any ideas Willi |

An oil analysis from an oil lab can tell immediately if it is condensation or coolant leak. antifreeze in the oil will destroy babbit bearings in short order. Caterpiller dealers have oil analysis capabilities.

PS you mentioned earlier "... all plugs looks good and looks the same. They would look different with blown head gasket" If the head gasket was severely blown yes there would be other symptoms too, but if the coolant is simply "weeping" through the gasket then there may be no change at all, other than occasional misfire or hesitant starting.

Re: Water in my engine oil. Where could it come from ?
Hello Willi:
Two places to check is first head gasket as typically number three cylinder will go first. Second is to remove side cover as Model A engines have weak area in valve chamber around number three cylinder and will crack and leak water into oil. see picture. There is a friend of ours in Aarau, Switzerland that can help you. He is Proficient in Model A engines. |

Re: Water in my engine oil. Where could it come from ?
Good Morning all...Years ago, I was taught that flat head engines should be re-torqued once a year, as they have a tendency to work loose and bolts can stretch and washers can collapse. All the suppliers sell a C shaped wrench to add to your torque wrench to make the job easy. They also have a chart that shows the tightening sequence if you don't have it...only takes half an hour and it is good insurance. Ernie in Arizona

Is the engine oil in the pan milky? If not, I would venture condensation!

Certainly worth a try! ( Reminds me of a 1950s book "Overlanding with Annabelle"- they had a cracked block in a Chevrolet truck and put in "Chemiweld" (whatever that was!) and successfully drove round Australia without any problems.

I have absolutely no reason to doubt that after using it, they were able to drive around the country and I bet the engine still running well for a long time after. It has been about here for decades and stories of miraculous "workshop in a can" feats are numerous.Here is a link to the manufacturers descrption: http://www.goss.com.au/assets/Upload...nformation.pdf I'm sure other sodium silicate products will work just as well. One of them might help out our original poster.

Run a compression test to see if the head gasket is compromised.
