Why did Haval h6 leapfrog intake branch pipe leak oil?

First, there are not only air holes on the manifold pad, but also water passages and oil passages. At both ends of the manifold pad, the front and rear ends are easy to leak oil and water. When replacing the intake manifold gasket, it is recommended to pay attention to whether the gasket is in place and apply the sealant higher and more evenly. You need to wait until the glue is completely solidified before starting the vehicle. The most important thing is to use special antifreeze to avoid mixing deterioration and corrosion of the manifold pad.

Two, for carburetor or throttle body gasoline injection engine, the intake manifold refers to the intake pipe from the back of the carburetor or throttle body to the front of the cylinder head intake. Its function is to distribute the mixture from carburetor or throttle body to the air intake of each cylinder.

For port fuel injection engines or diesel engines, the intake manifold only distributes clean air to the intake of each cylinder. The intake manifold must distribute air, fuel mixture or clean air to each cylinder as evenly as possible, so the length of air flow channels in the intake manifold should be as equal as possible. In order to reduce airflow resistance and improve intake capacity, the inner wall of intake manifold should be smooth.
