Not sure about thread continuity. If I erred, my apologies. Hard to keep it straight late at night after a long day at the salt mine.

I pulled the vent tube off of the intake ducting and put it in an empty bottled water bottle (clear plastic). After running it in stop and go traffic, flooring it and then traveling at highway speeds for about 20-25 miles, there was hardly any oil residue in the plastic bottle. If I have to leave it on there for 1,000 miles, I don't know if I can stand it. The fumes in the engine compartment from that vent tube are pretty strong........ and enter the passenger compartment even with recirculate air in the "on" position.

I burned about 1-2 quarts after traveling 400 miles this week. I dunno but it is sure starting to sound like a turbo to me.
