Spill valve is a overflow valve.
Wherever oil is handled there's a chance of a tank or a pipe bursting, or someone leaving a valve open. And that's all it takes for oil to spill out into the enviromnent
Valve Stem Seal are designed to make sure no oil will spill into the engine piston as it eat the gas coming from the Fuel injector through the exhaust manifold.
It is a quick response valve, which opens fully in 1.5-2 seconds. basically will be of fail open type. Its opening depends on the surge control.
The most common cause for lack of pressure with a karcher pressure washer is a stuck "spill valve". This is the assembly under the black cylindrical cover and push-on retaining nut. Pry up the nut, remove the cover, use a star hex wrench to remove the assembly. The spill valve itself is very difficult to remove. My trick is to hook up the water and turn the washer on briefly. The valve should fly out. Sometimes it takes a couple minutes when really severely stuck. I replace the orings...be careful, the older style uses a flat cut nylon back-up ring that is split...you will need to reuse that ring. Occasionally the spill valve is broke in two and needs to replaced completely. I swab out the spill valve housing with a bottle brush. First with carb cleaner. Second with mild acid or vinegar. Flush with water. Grease the spill valve with high grade water resistant grease and reassemble.
