I had to replace my thermostat in December so I saw the valves. They are gunked up. I put the occ on 6 months ago. I tried the Tracy Lewis $450 occ setup a few years ago that is why I have hole in the intake. It pulled enough vacuum under 1500 rpm to make the front main seal squeal. Had to pull dip stick to make it stop. Took it off.
