No. It would cause the coolant and oil to mix and it would look like a Milkshake drain oild and check it.
No, only a blown head gasket or cracked head will cause coolant to mix with the oil. A leaking valve cover gasket will only cause oil to leak onto the engine block externally.
Check: 1.- PCV vacum hoses 2.- Engine oil cap looseness. 3.- rocker cover gasket
you have a blown head gasket water is getting in to the engine oil
Hmm... it could be several factors. Is the Check engine light on? If so, see if it points to your fast idle control valve or air intake valve. Either one may be the cause of the high idle, especially if the idle is rough. The leak in the valve cover gasket could be as simple as replacing the cover gasket, unfortunately, it is difficult to assess the machine over the internet.
Yes, a leaky left bank valve cover gasket can occur as a result of engine overheating. When the engine overheats, it can cause the materials in the gasket to expand, warp, or degrade, leading to a compromised seal. This can result in oil leaks from the valve cover, which may require gasket replacement to resolve. Regular maintenance and monitoring of engine temperature can help prevent such issues.
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
You have to check the valve cover gasket from all sides. If it's not the gasket then you should check the break fluid level, and the break tubes around the passenger tire.
Bad engine seal? Bad oil filter? Leaking valve cover gasket?
Check the valve cover gasket, if not that you may have a warped head.
The head gasket seals the head to the engine block. Coolant and oil flow through the head. The gasket prevents then from mixing together. The valve cover gasket only prevents oil from splashing onto the engine and exposing the valve train and moving parts to the outside of the engine. No coolant makes contact with the valve cover gasket.
If the light is on, it will need checked and diagnosed.
