Step 1 is complete - I have replaced the air intake that has the orange gasket with a new air intake which has a black gasket and there was a lot of oil that has leaked from the air intake onto the swirl motor.
Step 2 - I am waiting for my aluminum plug to arrive from Kurt Kiefer at Shibby Engineering.
The original flow had the CCV air flowing into the stock air intake so I can assume that there needs to be some sort of vacuum in order to make things work (or in order to keep things as 'original' as possible).
My questions are with the catch can install -
1. Can I assume that if one of the hoses leaving the catch can is simply left to drain below the vehicle that it would be sealed. I believe I saw another member with a valve on the end of this hose and therefore could drain the hose periodically if there is any oil build-up. If this is the case would the sealed line cause any pressure upstream? Obviously the stock air intake system was designed to permit and even promote the flow of air? Would preventing the normal flow damage any components upstream?
I believe the member you are referring to has the elephant-hose-mod which does not use a catch-can. He just installed a plastic fitting on the end of the hose, not a valve. Regardless, you don't want to plug/restrict the outlet. A blocked or restricted crankcase breather will, at the very least, blow your dipstick out of the tube, while in the worst case scenario blow some engine seals.
2. If a valve is not used on the hose coming from the catch can I have read there is a chance that some oil vapour or oil may drip from this hose. If this hose is not directed into the air box and therefore there is no vacuum, is there a chance of damaging any component upstream?
well, yes that was my theory, I didn't want to chance damaging anything so I installed to the airbox, but it seems a number of guys have just an elephant-hose-mod and no issues with seals. The guys with the elephant-hose-mod do not have catch-cans so there is a reduced chance of a restriction.
3. Suzieque - do you have a part number for the "airbox fitting?" In order to install the air box fitting did you simply drill a hole in the air box? I am looking to install a Billet Technology catch-can in a similar fashion to yours and my only question so far is about this air box fitting you have installed.
Actually, when I first installed, I just cut a hole in the air box and stuck the hose into the air box through the hole and that worked just fine. After a while I just decided I wanted a more professional finish, so I spent some time at the auto parts store looking at a rack of PCV fittings until I found a fitting I liked. Sorry, I didn't keep the part number.
Are you still satisfied with this configuration? Is there any chance that the colder temperatures and potential for increased condensation will become a problem?
I installed this setup in May, so I've not run this configuration in the winter yet, but you raise a good question. Previously, I had a Racor setup where I did run the hose back to the stock air intake tube, not the airbox, so it basically used the stock inline heater to melt any condensation. The problem I noticed is that the Racor was not catching all the oil vapor, some oil was still getting into the intake. I will be more vigilent and look for condensation in my new catch-can. It is easy for me to check since the model I bought is clear and water would make the oil appear milky so I do know what to look for. Also, I park in a garage in the winter where the minimum temperature is +5 celcius (40 degrees fahrenheit). If you are worried about the condensation issue, then you should run the hose back to the air intake tube and utilize the stock inline heater for the winter.
