Aha !

Do as C 130 tells you !

Erson is cam maker, used to be independant now owned by holley or someone like that.

The valve covers are the stamped steel aftermarket types like the moroso ones I described before. I'll bet there is NO baffle in them. When you hook up the pcv you will get alot of oil being sucked into the carb and burnt = blue exhaust smoke.

Put the edelbrocks on there (assuming they are cast aluminum) and make sure you have a baffle under the pcv inlet. If your new edelbrocks are stamped steel then you will have the same problems as the erson covers. As I said before there is a type of grommet for these steel covers that has a baffle built into them. Hole size is probably 1.22", any car parts store should have them.

By the way your oil pan leak might get better once the pcv is working right.
