This is why you should run a catch can
Ok that's good by any chance do u have a picture of what ports I hve the weapon r catch can so I have two hoses but I don't know where they go ha
^ Sorry I more meant that tools and other sorts of objects have been starting to rust in my garage. However my car has not rusted. Living in Seattle has its moments.. I was maybe thinking for us running E, and those of us who let the car sit for long periods of time, maybe some of the fluid were draining is fuel/water. Although I took the torch to my fluid and it burned/evaporated.
Hello I Want to hear what you guys think is a good, respectable, durable catch can. I'm in the business of looking to buy one don't know where to start looking or which brands make them. I looked at the buschur racing one any thoughts on that one? TIA
The topic of this thread should be " This is what happens when you disconnect your PCV Valve "
The reason these people are experiencing large amounts of H20 in their catch cans is from the lack of a operating PCV system to remove the condensation in their motor. Water Vapor is a by product of the combustion process. Under boost the crankcase is further pressurized by the higher prssure which is pushed past the rings. Plus every time you start your motor you are adding more moisture to your non PCV'ed engine. After many hot , cold cycles you have what is displayed in their catch cans.
PS. On a daily driven vehicle, I would not recommend operating it with out a pcv system to purge the motor of the moisture.

I feel that this is the best with it's return port to the oil pan doubling as another pressure relief under boost. Therefore you do not have to drain the tank. If you run the PCV line to the old pcv fitting on the intake manifold and T off of it to the top port on this catch can you still pull a vacuum on the valve cover and the catch can when not on boost. I use a Krank Vent

directly off the manifold thus allowing the old pcv port on the valve cover to empty into the can when under boost. The can will only allow the moisture to be drawn into the combustion chamber which is harmless to your engine.

i did probably 150 pulls in my car the last week and i have not a droplet of oil or fuel in my catch cans.
heres the route i went; http://oi51.tinypic.com/2a5dkwg.jpg with a 5/8" fitting from the valve cover to intake, and standard from pcv to can.
more info here; https://www.evolutionm.net/forums/ev...re-issues.html
i still use a spring i got at ace hardware to secure the dipstick just in case, but i forgot to reconnect the spring the other day and did like 40 pulls and the dipstick didnt budge. the only thing most people need to do is just drill out a bigger relief hole in their valve cover and that will cure all the crankcase issues they have.. you could even run the line to the ground, you dont even need the catch cans really.. if you drill only where the old side port is, the valve covers baffled enough to stop all oil sloshing. the factory pcv system works fine once you allow the valve cover to breath better out the side. atleast for my driving habits.. which is mostly straight line WOT.

So from what I've gather one catch can would be enough I don't need to have two? As long as it has 3 ports and 1 vent on it your good? If I'm wrong please someone correct me. I'm thinking of fabricating my own catch can or buying a buschur one.
^I think it depends how much oil gets tossed out your valve cover side port. I barely get anything so I just run a breather filter. I've seen others like EvoDan that run a can there because sludge is collected. My 2c anyway..

It would be neat to see what it is. My theory it is from running E85, but I can't say for certain. All I know is that every hundred miles or so of hard driving, I drain that much from my car. I am sure it wouldn't ruin my engine going through, but everything stays that much cleaner by properly venting it out of the system 
moroso catch can here I come
