breather modification

[jomaripretty]

i have b20vtec and im planning to do breather block modification on my b20b as shown in picture, may questions:

will oil be coming out of the said breather, resulting in lost of oil
will it have any effect on lowering of oil pressure and its delivery to head

Oil vapors will be escaping out of those two holes. It's important to have a larger diameter than what is shown otherwise it will result in high pressure and oil will be drawn up along with the vapor.

These two holes have no relation to how oil is delivered to the head - unless you lose a lot of oil because the venting hoses are too small.

one of those 2 ports are wet. i cant remember which 1. the old z10 breather kit didnt have a drain back and it use to fill the breather tank up with oil very fast. like 4-5 pulls.

should look into buying the kit from endyn or u can buy everything sperate for cheaper through summit racing.

If your just going to use those two ports i suggest you have another port at the bottom of your can and T it into one of those to act as a drain back.
