Air valve leak/discharge - normal?
After initial engine startup and building air pressure, this right front valve blows air after pressure has built. I can't tell for sure exactly where the air is coming from at the valve around the valve. Is this a normal pressure relief? After a while everything seems fine and I don't hear any air leaking, but I'm wondering if this is normal or an indication of a needed repair?
Thanks.
