Puttered around a little today and still seems to be running good. I didn't really run it hard and noticed I didn't have the blowby when I got back, but wasn't out very long.

Jerry, I think the picture is a little deceiving as there's a good bit of space between the PCV hose and the solenoid. However, good food for thought as I should consider what would happen if the breather cap came out of the valve cover and was bouncing around in there. Are there covers for the solenoid connections similar to battery terminal covers. Seems a good idea to cover those up regardless.

Carnut, I think what Gessford uses is a steel wool filled "basket" under the breather that provides more barrier for the oil to go through. Had one on the old intake that seemed to work. However, stupid me, when I drilled out the plate on the new Edelbrock, I drilled the hole to match the size of the opening on the breather bottom - not the standard size hole that the basket fits.

Well, looks like I'll have to take the hole saw to the other valve cover and stick a breather in there. Is there any science to putting the breather on the front vs the rear of the cover? I was thinking it would at least look symetrical if it was on the front and matched the other cover, but then thought having it opposite (on the rear) the passenger cover would have more cross flow diagonally across the block. Suggestions?

Going down to Jekyll Island for the week and broke down and bought some street tires (Firestone Indy 500s) from Tire Rack, so will get those on when I return and then really give it a run. The left rear Goodyear is showing cords and I think is about to bite the dust.

BTW Dan, I used your tag line on my wife today because she was in that mode......she didn't seem to think it was nearly as funny as I did

Make sure you put the hole between a pair of cylinders so there isn't a valve under it. Ideally you should have a baffle (on both sides). I use these:

They're made for Chevies, fit in a 1 1/8" hole. The problem with them is the hole in the center of them is too big for a PCV valve; I find a grommet that fits a PCV (or breather) and has a long enough shank so that it will fit down in the Mr. Gasket #5425 baffle. The OD of the grommet doesn't matter, as I sand it down on the belt sander so that it fits snuggly in the baffle.
DSC Motorsports (and others) sell a plate that fits over the hole in the intake the rear breather goes over with different holes or no hole. You could buy one of those to cover the rear hole in your manifold and it would look factory. You could also drill a hole the correct size to fit your breather and sandwich it between the manifold and breather if you choose.
Sorry your wife doesn't have a sense of humor.

Dan
