Now that I have a handle on Weber fuel plumbing, I am moving on to oil vapor hoses. The engine I am installing is my first with carbs. Can someone tell me what the two small open pipes beside the intake manifolds are for? I assume they are on stock FI engine and I just never noticed them.
I believe I need some sort of vapor cannister (have seen one made by K&N). Do I connect it to the plastic nipple at the oil filler and then to the two nipples at the manifolds? Is this a crankcase vent system? Is there a PCV valve needed? By now you can tell that I'm not real sure I know what I'm doing! |

Jim,
Are you working on a 6 or a 4 cyl car ?? Our thread about the fuel setup had me thinking all along that you where working on a 6cyl car. We bring all three together into a common "junction" heads/oil filler. The ideal situation would be to pull a vaccuum on the heads and the oil filler like the factory did... but since you have dual carbs.. this isnt going to happen. You will end up with a catch can of some sort that left over oil/vapor will accumulate into. B |
