A stuck open thermostat will cause a car to run cooler than needed. It will cause oil to sludge, a loss of gas mileage due to running rich and numerous other problems.
on 2.4 models,crankcase vapors pass through a hose connected from the timing cover to the oil/air separator. a plugged oil/air seperator will cause excessive crankcase vapors and sludge buildup. no pcv valve!! or a plugged hose.
It will cause the oil to sludge up over time.
Yes. If stuck closed the car will overheat. If stuck open the car will never warm up properly and the oil will slowly turn to sludge.
No, the check engine light will come on at first, and in the long run the oil will sludge up form running to cold.
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.
if sludge is keeping oil from draining away from valve guide a cylinder can suck in oil and cause plug to misfire
The positive crankcase ventilation or PCV system uses engine vacuum to draw crankcase vapors into the intake where they are directed into the combustion chamber and burned. This keeps pressure from developing in the crankcase which could otherwise cause gaskets and seals to leak. It also reduces sludge build up by drawing out water vapor. Once the engine reaches 212 degrees Fahrenheit (100 degrees Celsius) water in the oil turns to steam and is extracted with the other engine vapors.
The primary cause of a thermostat malfunction is corrosion. It prevents the thermostat from opening and closing as it normally would.
Its called Positive Cranck Shaft Ventilation PCV Valve. a one-way valve on a motor-vehicle engine for regulating a pollution control system that draws crankcase fumes into the cylinders for burning. Besides totally eliminating crankcase emissions as a source of air pollution, the constant recirculation of air through the crankcase helps remove moisture which otherwise would cause sludge to form. Thus the PCV valve extends the life of the oil and engine.
Yellow or "milky" sludge on oil filler cap is caused by short, frequent driving and not allowing engine to reach operating temperature because crankcase vapor, inside engine, isn't being allowed to "boil" off of crankcase and starts to film on engine block. Shutting off engine when it's not at operating temperature will cause it to stick to engine then restarting a cold engine, driving short time will start this all over again. Always allow engine to reach operating temp, it's ok sometimes but not all the time.
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
