Oil coming out of the breather

[94GPGTP]

So i am driving my 5 speed TGP as a DD right now since im down a car.. I had the engine rebulit no less than 1500 miles and just about a year ago.. I changed the oil 2 days ago.. but ever since i had this engine running i had oil coming out of the breather.. It wasnt alot but now its alot and drips onto the Manifold and creates smoke.. I have no clue what it can be since since its all brand new.. PCV has been changed so thats outta the question.. here is a few pics of how bad it is.. There is a puddle on the valve cover..

Do my eyes deceive me or is that a brake vacuum booster check valve you are using for the valve cover connection? If it is, then you have effectively blocked off the PCV inlet for the engine. Also, you should be using an oil/vapor seperator/catch can to eliminate the mess. In addition to that, did you check for good vacuum at the PCV valve? Are you using an AC Delco PCV valve dedicated to your application? The aftermarket is notorious for improperly calibrated PCV valves. Finally, at idle with the vacuum consistent and at better than 16" hg, there should be zero pulses coming from the PCV inlet on the front valve cover. One of my tests is to place a two inch square of notebook paper over the hole at idle. If the engine is sealing well and the PCV is properly secured and of correct calibration, the piece of paper should hold in place. If not, either the PCV system is incorrect or excessive blow-by exists which would warrant further inspection.

You are correct it is a vacuum booster check valve but i have gutted the inside.. So basically its just a 90 to help slow the oil from coming out.. The PCV has been replaced but not with a AC Delco one.. At idle and reading my autometer guage i have about 25 lbs of vacuum.. Im going to try your paper idea..

Is there any store bought canisters out there to catch the oil and be a breather?

I was always under the impression that catch cans were expensive (I've never really priced them). I did find a site that I had bookmarked some time ago where an autocrosser driving an S2000 made a homemade catch can.

You can also see if it is possible to attach some kind of baffle inside the valve cover to keep the oil splash from hitting the hole. Also, I suggest a leak down test to check cylinder sealing efficiency.
