Oiling issues

I am in need of some knowledgeable advice. Once again I have been plagued with engine issues. This is a fairly new race engine. Never been raced. Only broke in and ran a few other times. I am having an issue with getting oil up to the passenger side rockers. All of the push rod tips at the rockers are dry and blue . Driver side is fine plenty of oil. I am at a loss. Any insight to what the hell might be going on would be greatly appreciated. Thanks in advance
