Hey, BMRisko. You know me from the other site, and I'm looking at adding one of these, too. Can you post pics of how you have everything installed - which lines go where? You are bound to get some good answers on this forum.
Do you still have the blue smoke at startup?

I haven't driven it since I got home from my 100 mile trip. I will start it up in the morning and see how the blue smoke is. My main concern at the moment is the amount of oil that was in the can.
If you look at the first pic on page 1 in this thread, you see the stock plastic tube running from the pcv valve on the rear of the driver-side valve cover to the top of the intake. I removed this and did this: (sorry for the crappy cell phone pics)
You can make out the black rubber tubing leading from the back of the d-side cover across the front/top of the intake (under the vortec cover) and over to the pass side, where the catch can is mounted to the front of the block.
Looking down at the can, the right side is the inlet, left is the exit. The can I got appeared to be bi-directional.
The tubing exits the can and goes back over the top of the engine and attaches to the intake where the stock plastic hose was disconnected from. I can not see anything wrong w/ this set-up and am still baffled as to why I am filling the can so fast. Could the 3' runs of hose be creating some abnormal vaccum? I don't see how that's possible, but you never know...

Well I started it up this morning and no blue smoke, which usually would have happened after driving it 100 miles on the interstate @ 75-80 and then letting it sit overnight. Now if I could make it stop filling the can so fast.
Am I overlooking something with how I have the can installed? What else could be pulling all this oil through?

I just came back from running a couple errands around town and there was already almost a tablespoon of fluid in the catch can.

I'm about to go drive ~120 miles and I'll report back w/ any observations later on. In the back of my mind, I am fearing a bad ring though.
