Many thanks gents! To answer the above questions:

1) My car does NOT have a breather on the rocker/valve cover, but it does have the vented oil cap.

2) Oil pressure readings using the in car quadrant gauge (which still has the dedicated oil line) runs around 50 psi (midpoint), at least it doesn't look to be running high.

3) My car DOES have the convoluted breather pipe on the left hand side of the engine block (about 1 1/4 inch in diameter, with a beveled end)...can this get plugged? Any tips on how to clear it?

Many thanks!
