I have a valve slapping sound the day of boosting...drew oil from headport
I installed everything fine, replenished oil and everything. The car runs great, but there's a loud rattling/nocking coming from the valves....I think. My oil feed is coming from the headport by the VTEC sylonoid. Is this taking too much oil from up top? I think it's only 1/8 diameter hose i'm using. So, give me your input. Thanks.

I think it's just a test port that makes sure you have pressure if VTEC is malfunctioning. Any other suggestions?

its probably a rod knock. most people mistake a rod knock for valve noise because the sound seems to come up through the head.
