The Official Hot Rod Thread - Part 2: No Replacement For Displacement

[RustyHornet]

My Pontiac 350 has some blow by. Not a big deal but it spits out the breathers quite a bit, and the oil spots in the driveway are annoying. Sooo....baffled valve cover breathers? There’s a provision on my air cleaner for a tube, so I get an elbow to fit the valve cover and hook it up that way?

Factory PCV system FTW! I forgot to look through my stash to see if I have any of that...

Needs to be. And block off the open VC breathers. This is a must.

Otherwise it becomes a vacuum leak?

A huge one. Depending on where and how you connect it.

PCV won't necessarily correct the over pressure problem. I was relying on a pcv valve to to vent the crankcase and that valve requires a certain amount of pressure to unseat it and vent the crankcase. In my instance it took move pressure to vent the crankcase than it took to force oil out of various locations it wasn't been to be forced thru. I ended up installing a simple vent hose from one valve cover to the bottom of the air breather to give a non pressure dependent path for crankcase ventilation. Oil leak problems solved It's not exactly what I'd call pretty but until I get other issues worked out I'm not too concerned about "pretty".

Works a lot better if the lid is sealed to the bottom but this will work.

Plus it will run better in the configuration pictured....and sound better...

I tried it on the BMW but those plastic boxes and square air filters were engineered to stop the best free "hi po" mod out there!

I would say I always knew you were a closet Poncho guy, but the fender flags tell me different...
