I would change PCV valve before changing cover gasket. Sorry, no RU keyboard
you have cover gasket leaking not head gasket - две большие разницы
Спасибо за совет!
А вы можете подсказать почему ваше мнение, что надо прежде поменять PCV valve, а потом гаскет??
A PCV valve, or Positive Crankcase Ventilation valve, is a crucial component of your car's engine that regulates the flow of gases from the crankcase back into the intake manifold to be re-burned. It helps to reduce emissions, prevent oil leaks, and maintain optimal engine performance.
Here's a more detailed explanation:
Function:
The PCV valve is a one-way valve that allows gases to flow from the crankcase (where the crankshaft and other moving engine parts are located) into the intake manifold. These gases are a byproduct of combustion and contain harmful compounds.
Why it's important:
Without a functioning PCV valve, these gases would accumulate in the crankcase, potentially leading to: Increased pressure: This pressure can force oil past seals and gaskets, causing leaks.
Oil contamination: The gases can mix with the engine oil, leading to sludge and increased wear.
Higher emissions: These gases would be released into the atmosphere, increasing pollution.
How it works:
The PCV valve regulates the flow of gases based on engine vacuum. At idle or low speeds, when vacuum is high, the valve restricts the flow to prevent overly lean air/fuel mixtures. As engine speed increases and vacuum drops, the valve opens more to allow for proper ventilation.
Signs of a faulty PCV valve: Oil leaks: Especially around seals and gaskets.
