After running a 15 minute track session, I have excessive fluid spraying out of the vent on the power steering pump cap. It's quite a bit, enough that it's dripping off the hood, on the valve cover and firewall. My guesses are it's either heating up to much(boiling) or from high rpm. Is there a remedy for this issue? Should I run less fluid for the track? I'm guessing it's not a good idea to plug the vent.?
