Hello, glad to have advice please. I have oil leaks from above (valve covers) and oil on the oil pan from below. Besides, I also have leaks on a tube that will be sent to you in the video, have to know where is the exact problem. Because I am tired of hearing different opinions. Some told me it is a piston crack and excessive blow by, others told me that there is nothing significant, but I am having oil consumption about a quart at each 4000 kilometers, letting you know that there is no exhaust smoke.

Thanks for the video, it helps. This happens when the PCV valve needs to be replaced. Here is the location and how to replace it, to see if you have an internal engine problem such as a piston (which I didn't not hear in the video) while the engine is idling remove the oil fill cap to check the pressure, it should be minimal. If you are unsure, please upload another video so I can see.

REMOVAL

Push in on the tab (1) to release the quick disconnect and remove the hose from the PCV valve.

Release the lock tab (2) and turn the PCV valve (1) clockwise and pull out to remove from the right cylinder head cover.

INSTALLATION

Clean and inspect the sealing surfaces of the PCV valve and cylinder head cover. Lubricate the O-ring seal with clean engine oil.

Install the PCV valve (1) into the cylinder head cover and turn counterclockwise until the lock (2) engages in place.

Install the PCV hose (1) onto the PCV valve.

Check out the images (below). Let us know how it goes.

This is totally normal, the engine looks like it is in good shape, I would just replace the PCV valve and that should fix the problem. Thanks for the video.
