Oil catch can solved one problem, created another.
Oil catch can solved one problem, created another.
I've put in a vented oil catch can earlier this week.
All seems to be running well, no codes.
As I did more driving with it, I discovered a new problem that catch can created.
I get serious amount of oil fumes coming out of the catch can. When car is in motion, you cant smell them, but when stuck in traffic the fumes are felt in the cab and it's pretty bad.
I wonder if my cab filter will solve that problem. I have not replaced mine in a while now.
For plan B I'm thinking to vent those lines under the car. After all the catch can is nothing else but a vented line with a can that catches oil. Except that it vents now under the hood.
What ya all think.

just vent the lines outside of the engine bay. i think the cabin air intake for our cars in under the battery. so as long as the lines vent out or under the car i think it will be ok.
The vent into the car is right in front of the passenger seat dash. Bring the vent to somewhere on the drivers side with some cheap rubber. This will make the smell disappear.

A closed catch can still creates vacuum in the system so not all oil vapor is settled and some still sucked in into the intake. The key to eliminate all oil vapor to go into the intake is to vent the line and eliminate the vacuum.
That's wat I always wondered
Joker is there a reason we generally disagree? When I installed my MD spacer I found oil residue in my plenum. Contacted my friend Dave O of Nissan Sport mag in '05 knowing he'd installed a catch can in his ride. Installed the Home Depot can like he suggested. A few months later I installed a polished upper plenum, this time there was zero oil residue in the plenum. Joker maybe you should rethink using an open catch can! Currently using a closed C6 Corvette catch can, SLICK has 56K miles on her and uses zero oil between changes...Gary

How much oil you get in your can between the changes?
I have a closed HD catch. It catches a lot but I also see residue on the outlet hose as I have clear hoses. Did not help with oil sippage.
I don't see how a closed can is to reduce consumption if the pressure isn't relieved.

Another reason why I went with vented can, because my setup eliminated both vapor lines. From the front of the engine and back of the engine by the throttle body
Most closed cans only put in line between the valve cover and plenum. Nothing is being done with another line that goes from the valve cover and the intake tube.
I eliminated both lines and vented them through the can.
I think what I'll do is take my can out, put small home depot air/water separators on each line and just vent them down below the car. That way I'll catch the oil out of the lines and bent the lines below the car to eliminate the smell.
