I have a quick question, I have a 68 coupe with a 302 motor in it. It is actually an 80's 302. I have M/T or mickey thompson valve covers on it. I have a breather cap on the drivers side and nothing on the left ( passenger) is there a problem with leaving it this way for a while or should I upgrade to cobra valve covers and have a pcv valve on that side?
Should I also set it up so a tube connects the pcv to a port under my holly carb. any thought?
I'm concerned that I should be venting on both sides
