Most likely a blown head gasket. Foam or froth is caused when antifreeze mixes with oil in the crank case. Could also be a leaking radiator if it is a dual engine/transmission coolant system.
Can also be you overfilled it and the crankshaft is making contact with the oil creating a froth of air mixed with oil. Drain the excess out if it is overfull, as this will destroy the engine.
If it is high enough to be splashed by the crankshaft it would foam up. That would cause a lack of oil pressure and engine damage.
Viscosity breakdown
Well, doubtful. Overfilling can cause oil to foam as the crankshaft whips air into it. Foam can cause hydraulic lifters to operate incorrectly. But you'd have to overfill by several quarts to do that.
Yes it can. To much oil and the crank can turn it into foam. Which will cause a loss of oil pressure. This can lead to engine damage and over heating if you run it long enough.
I wouldnt. The heat would cause the foam to melt and possibly catch fire
Harley motorcycles may puke oil due to a few common issues, such as overfilling the oil tank, which can cause excess pressure and lead to oil leaks. A malfunctioning crankcase ventilation system or faulty seals and gaskets can also contribute to oil expulsion. Additionally, riding the motorcycle at high RPMs for extended periods can cause oil to foam and overflow. Regular maintenance is essential to prevent these problems.
No, foam is not recommended for oil fires as it can actually spread the fire and cause it to flare up. Foam is better suited for extinguishing class A and B fires, such as wood or paper fires. For oil fires, it is best to use a fire extinguisher specifically designed for class K (kitchen) fires or a fire suppression system designed for commercial kitchens.
There are a couple possibilities for foam in a gearbox. Gear oil is created with an anti-foaming additive in it, so if the fluid starts to break down because of normal wear, then it will start to foam. The solution is easy. Just change the fluid. The second option is that it got water in it, and the water will cause a foam. Also, just change the fluid.
The foam is atomized oil. Crankcase oil flows with the freon.
Water is getting into the engine. Change the head gasket before it blows.
I have to assume you are talking about an automatic. But in either type of tranny the fluid will over heat foam up and expand, causing pressure in the trans case which could blow out some of the oil seals. this would cause a major oil leak and reduced life expectancy of the tranny.
No, that's caused by oil problems (sludge, foam, improper oil change schedule) or sometimes just plain engine age.
