For those running dual carbs, how do you attach a crankcase breather hose to the filters? Especially if you have K&Ns, which I plan to replace. Do you run two hoses? Got pics? (IMG:style_emoticons/default/sawzall-smiley.gif)

I received a PM question(s) that I'm going to answer here in the event that it may help someone else.

Gint,
So you have dual 40's on a 1.8L right? How are you venting your crankcase? Just at the oil filler? what are you running that into? How's the car runnign with this setup? I spoke to a tech over at auto atlanta and he said this should be fine. He also said just run the blowoff under the bottom of the car...
Appreciate your input


Yikes... one question at a time!
  • My mill is a 2056. 2.0 crank and rods with 96mm P/C's on a 1.8 case and heads with dual 40IDF Webers.
  • I currently only have a vent running off of the oil filler with a long hose running up to a small K&N type breather filter near the upper left corner of the engine bay.
  • The car runs fine. The carbs could stand to be jetted so that it runs less rich, but that's a task and conversation for another day. It does leak oil like the Exxon Valdez though. Probably from the push rod tubes and or oil sender. I suspect that the inadequate breather setup could also be a contributor to that condition. Gotta fix those one of these days...
  • I would not just run the blow-off under the car.
My breather filter pollutes the engine bay with oil vapor. Not horribly bad because it's still pretty high, but bad enough. I believe this is primarily because the current breather setup is not adequate. Regardless what an AA tech says. And if you run the hose under the car, the oil vapor will just pollute the underside of the car instead of the engine bay.

If this motor stays in the car much longer (probably won't), I plan to get a breather style like the one in this thread and vent the heads. That's what this motor really needs. Yours may be different, but I doubt it.
