Oil foaming can be caused by several factors, such as water contamination, high oil levels, or mechanical issues in the engine. When water mixes with oil, it can create foam due to the agitation of the oil. High oil levels can also lead to foaming as the oil churns excessively. Mechanical issues, such as a malfunctioning oil pump or excessive air entering the system, can also cause foaming. It is important to address the root cause of the foaming to prevent damage to the engine.
Possibly,Rabies.
Grease foams when you cook because of the presence of water or food particles in the hot oil. The water evaporates rapidly, creating steam that gets trapped in the oil, causing it to foam. This can happen when cooking foods with high water content or when the oil is overheated.
I'm in the process studying for my epa test and this is one of the questions and their answer is foaming occurs in the compressor.
Disodium cocoamphodiacetate is a surfactant derived from coconut oil. It is commonly used in personal care products such as shampoos and cleansers as a mild cleanser and foaming agent. It is known for its ability to remove dirt and oil from the skin without causing irritation.
Alginate
Plant foaming and polymer foaming
bad gasket
Foaming at the mouth is NOT an actual sign of rabies. Most likely scenario is that the wolf that is foaming at the mouth has just run very fast or very far, causing it to salivate.
You need to have the oil pressure checked. It could be a worn engine or thin oil causing that.
Sounds like distemper
Foaming often indicates that the fluid level is too high. Maybe you overfilled the oil? Rough running could be many things. If you haven't changed plugs and plug wires lately, that could be a good place to start. FriPilot
Could be gas in the oil causing low or no compression.
