the car was fully warmed before I performed my "test".
suppose I have to "argue" again with the managers in Honda dealerships.
should I asked them only for compression test or for leak down test as well ?
any other options ?

Just to clarify, if you simply hold a piece of paper near the hole it will most likely blow away (or just blow around). But if you push it agains the opening for a second it should stay there when you let go. It might flutter and make a lot of noise, but the PCV system will hold it there. I just checked it on my car and if I hold the paper an inch or two away from the oil fill it will seem like it is blowing away. But if I push the paper down until it contacts the opening it will stay there from the slight suction.
It is the same with the dipstick hole. If you simply put your hand above it you will feel a lot of air moving and it will feel like a constant blowing, but if you put your finger against the hole (sealing it) your finger shouldn't feel like it is being pushed away.
If your's blows the paper away no matter what then I would think you have a blow-by issue.
You could try explaining the test you did to the dealer, but that may or may not help. "But a piece of paper over the oil fill blew away"
, might not go over well. But who knows.
