how can i remove?

Answer 1

If your car is used for short trips to the store and back, it does not have a chance to warm up completely to evaporate the moisture that gets drawn into the engine as it cools down.

If after taking it for a long drive one hour or more, if the moisture doesn't go away, you may want to seek proffesional help.

It could be a leaking head gasket.

With the engine warm, and coolant topped of, look for bubbles in the overflow tank to the radiator. That would be one indication of a leaky head gasket.

Answer 2

This is a touchy one...Some cars are prone to slight condensation buildup in the filler neck, but it isn't always a problem. It should wipe off with a rag...

HOWEVER, it can also be an indication that there is a small leak in the head gasket...I would recommend you have a shop do a pressure test on your cooling system. Have them do one test "engine cold", and one "engine hot", since a small leak may only show up one way.

Any pressure drop after 10 to 15 minutes indicates a small leak may be present, head gasket or something else...

Answer 3

Seems like a little bit of moisture, engine needs to run at operating temperature which is 200 degrees

Answer 4

1. PVC valve is not functioning

2. Head gasket failure

3. Engine operating too cool, due to malfunctioning thermostat

4. One dead cylinder – fuel leaking into crankcase
