Quote: absolutely no smoke out of the exhaust... i have seen a lil oil dripping from the breather but only at the track
I would try running a tad less oil, maybe a 1/4-1/2 qt. I would prefer you do a leak down, but if you don't have the gauge or can't borrow one,that's your only option. The only other thing I can think of that would cause crankcase pressure other than a worn out engine, worn cam,etc. is too much oil. Are you sure you only have 5 qts? Stupid question....how old is this motor? If there is any way you can leak it down, do it.
