After pulling the motor to do a full bay tuck and shave I've finally reinstalled everything, the only changes I made to the engine was I tapped the valve covers for -10 fittings and ran a catch can from tms. Now while running the engine it seems I am getting an excessive amount of smoke coming from the can. The engine was rebuilt I'd say 5k ago with 9.0-1 cp Pistons bored .040 over, gsc s1 cams. I know that some smoke is common especially without a vacuum source to draw out the fumes but this seems a little much. Any idea what would cause this? I've done some searching and all I really found was blow by gases but with a fresh motor I don't see why I would have this much. I will post a video link a little later when I get a chance to run the car. Any input is appreciated thanks.
