14 Jul 2015 A good quality engine oil should not foam up because of the anti-foaming additives that are mixed with the product. There could be several  Oil flows through dozens or hundreds of tight spaces inside your engine -- particularly in the valvetrain -- and every time it does it picks up a few air bubbles.

Simple as it can be, air bubbles may actually turn out to be dangerous. Overtime, they may cause overheat when trapped in car engine cooling system. This is more serious than it sounds, as the bubbles can build into an air pocket and not allow coolant to pass. White, milky oil.

Oil flows through dozens or hundreds of tight spaces inside your engine -- particularly in the valvetrain -- and every time it does it picks up a few air bubbles. Under normal conditions, these air bubbles would simply pop in the oil and release into the crankcase, but very cold oil tends to trap the bubbles and turn them into foam. The owners manuals usually state to check the oil at normal operation temperature, 5 to 10 minutes after shutting off the engine. With the engine warm thermal expansion is accounted for. After sitting over night there could be an abnormally high reading from the oil that has drained from the upper engine parts, you want an oil level reading that is close to operating conditions, not one of a parked vehicle. Bubbles are normal. Oil goes through he!l and back in the engine. Bubbles float to the top and is a good thing. So your dipstick will have a few. Not an issue. Just make sure that your oil level is correct. The big issue is when the bubbles don't float up quick enough and get pumped through the engine. Air isn't a good engine lubricant. if you put to much oil your crankshaft will wipe in to it and cause bubbles and inside bubbles is air and air does not lube the engine at all. it will ruin it. If you hear bubbles in your stomach If your head gasket was bad, you would almost certainly find oil in your coolant or vice versa. The suggestion that bubbling was a symptom of the head gasket is probably linked to the idea that

Any of these could be signs of a blown head gasket. Oil Consumption There are just as many oil passages in the cylinder  A more serious problem is how the bubbles got there.

Oil flows through dozens or hundreds of tight spaces inside your engine -- particularly in the valvetrain -- and every time it does it picks up a few air bubbles. Under normal conditions, these air bubbles would simply pop in the oil and release into the crankcase, but very cold oil tends to trap the bubbles and turn them into foam. Oil that is a whitish milky color is contaminated with water, while oil that is a greenish milky color contains antifreeze. If the water is the result of normal condensation in the engine, the milky color will disappear once the lawn mower engine warms up. If the oil still looks milky after the engine warms up, The owners manuals usually state to check the oil at normal operation temperature, 5 to 10 minutes after shutting off the engine. With the engine warm thermal expansion is accounted for. After sitting over night there could be an abnormally high reading from the oil that has drained from the upper engine parts, you want an oil level reading that is close to operating conditions, not one of a parked vehicle.

The oil coming from the other components (pressure regulator and unloader valve) is a sure sign that the oil is still suspended in the air and not falling to the bottom of the inside of the receiver. edit:
