A crankcase would be the lower portion of an engine block that houses the crankshaft.
There are two! One by the oil filter cap and the other is at the opposite end of the crankcase. They don't look like drain plugs, but they are.
To find the positive crankcase ventilation valve, look on the right bank of the engine. The valve is located beneath the intake manifold.
usually a small metal elbow shaped tube thicker than a pencil but smaller than a marker. It will be plugged into a grommet on valve cover/crankcase somewhere with vac. hose attached going to carb/induction. It's a 1-way valve to burn crankcase gases.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
replace your PCV first if it persists you will need to look into why you have so much pressure in the crankcase.
open crankcase ventilation and closed crankcase ventilation.
Crankcase - Transformers - was created in 1989.
crankcase oil is the oil in the engine .some call it crankcase oil some call it engine oil
It is flooding liquid back to the crankcase
A leak in a hose or the radiator itself. This should be obvious. Possibly a head gasket. If it is going out the exhaust, there should be white smoke, if it is going into the crankcase, the oil will look like chocolate milk.
On a Suzuki Boulevard C90, a positive crankcase ventilation (PCV) system typically includes a PCV valve connected to the engine's crankcase and intake manifold. This valve allows for the controlled release of crankcase gases back into the intake system to be burned off, preventing pressure buildup and reducing emissions. The system may also have hoses and fittings that ensure a proper seal and efficient airflow. Visually, it may appear as a small, cylindrical component integrated into the engine layout, often located near the air filter or carburetor.
Generally speaking, the crankcase is the lower part of the engine. It's where the crankshaft connects to the piston rods. If you drop the oil pan and look inside, you'll be looking at the crankshaft and the bottoms of the piston connecting rods.
