I've also seen folks cap them off altogether. One reason I like Indiana, no emissions tests .
That would still pass the federal emissions regulations because it doesn't bypass any of the emissions equipment. It just makes it so the entire bulk of fumes has to pass through the PCV valve instead of using the direct head vent.
I'm not a lawyer, though. I could be wrong about that.
I ran one for years, the vc vent that goes to the intake pipe, leave it alone, that way the pcv is pulling metered air thru the vc instead of atmosphere. As long as you don't vent the catch can it should be legal. The only difference in the whole system would be the catch can and its just giving the oil vapors a space to condense and collect instead of going directly into the manifold.
Wow. The answers are all over the place, haha.
I'll look into the construction and placement of the catch can while everyone decides where it should attach
Plug the intake side and install a breather filter on the VC.
I drove mine to Greenwood to meet up with Spike, then made my way to Southeastway Park to check shelter availability as a backup plan for...
IndyStiva!
Illegal.
Also, creates improper PCV operation because the vacuum from the PCV will pull from the easiest path, so instead of pulling the fumes from the block like it should, it'll just pull air from the filter on the other side of the VC. I'd sooner put a bolt in the hose than use a pod filter.
I thought about a catch can. Should I do it on the PCV line or on the little tube that runs directly from the valve cover to the intake piping? I know I have some oil getting sucked in there as the intake piping always has some in it.
I'm not really sure. I'd try both and see which one has more crap in it.
