LT-1 Valve Covers

[George C.]

I have a 1970 LT-1 with the stock aluminum valve covers and stock PCV valve CV746C.

I am getting oil splashing and oil being suck into the PCV valve and hose because their is no internal baffle inside the valve cover.

Has anyone come with a solution to this problem?

If there are no internal baffles inside the valve covers at the PCV system orifices, then someone must have removed them. The valve covers were originally supplied with integral baffles, as ineffective as they might be.

George i checked the corvette central catalog to see the baffle you are missing.i don,t know why it is not there..are the oil drain holes clear ? No milky or thick oil buildup to plug them . Peter .

It's just the baffle are missing under PC valve in the valve covers. The return holes are clear and no sludge or milky oil. I engine was rebuilt about 1500 miles ago.
