I find lots of bubbles in my engine dipstick.anyone know what happen to my engine ?

 

What oil is it? Oil companies use anti-foam agents that control this. Sodium is one sucj additive. I have also seen where oil stabilizers actually hinder an oil's ability to remain stable (counter-productive).

Another possibility is an overfilled crankcase, which would cause cavitation and foaming.

 

Oil this Honda factory oil~~~
Its that an problem ?

 

It sure sounds like it. Are you over-filled?

 

 

Overfilling is a very real possability.
If the oil is so high the crank is slapping into it, you will get thousands of air bubbles.

 

 

Royal Purple at the correct level FTW!

 

any oil at the correct level ftw.

 

there is soap in your oil pan. using dish detergent in your motor is a great idea... the dish detergent provideds a much smoother lubrication for the pistons
