The Ford Barn

charlesea · 01-31-2016, 05:25 PM

I recently changed the oil in my car which has ran fine all year on several tours. I have had an issue with the gas cut off leaking & installed a new cut off yesterday. I have a Webber carb & when I checked the dip stick the oil was milky. Does gas turn the oil milky or water?
Water level is fine. I have not driven the car 50 miles since the last oil change.
Needless I drained the oil pan today.
Thanks for FB'ers that help keep Shasta going.

Water turns it milky

Fullraceflathead · 01-31-2016, 05:31 PM

Milky oil is oil contaminated with water.
Gas in large quantities in oil will just thin out the oil and smell like gas.
Fresh oil after fixing water leak is a must.

A lot of gas in the oil it You can light the dipstick with a lighter... It will not get milky from gas
Could be condensation built up from short runs

Thanks for the fast replies. I have only been on short runs during the winter. Now I have a good reason to drive Shasta on longer runs. Hope that is all & not a blown head gasket.

if you have a down draft carburetor and your fuel shut off valve does not shut off completely fuel can run down past the carburetor and fill the manifold and then drift down past the valves and the rings and into the pan. Several club members I know of had this happen to them. If you really do have fuel in the pan you should remove it to clean it out thoroughly, then address the fuel shut off valve.

This doesn't happen with an original updraft carburetor because a faulty shut off valve and a leaking float valve will deposit the fuel on the garage floor.

I've seen engines destroyed by fuel leaking into the manifold like this. It washes the oil off the cylinder walls and shortly after start up, the piston grabs the bore. Pour some oil down there before you restart the engine after this happens and you have FIXED THE CAUSE.

sounds like water in the oil
just draining the oil is not good enough
as some oil stays in the baffle
refilling the pan will just mix with the baffle oil

Retorque the head.

May want to also do a compression test. This may tell you if you have problem with head gasket.

WestCoast · 02-01-2016, 04:18 PM

this is one time you would want your radiator full to the top, if the head gasket is leaking into the cylinder you will see bubbles coming up to the top of the radiator fill neck

if the oil is milky its because there is water in it
