Added some rooler rockers to the 502 but had to put on some aftermarket aluminum chevrolet valve covers with no baffles. Tried two vents but oil leaking all over. Hate to put a PCV valve in the grommet cause it would suck me dry. Tried a breather with a 5/8 hose to the air cleaner but still getting oil in carb. Hate to have to buy a 150.00 puke tank. Any suggestions??
