How important is an oil catch can?

 

it's definitley a good investment. It's obviously not a performance upgrade but more of a safety upgrade. Keeps the oil from getting into your intercooler which is really important.

 

Can you put in inline with the pcv valve or does it screw up the idle?

 

Plumbing the can is relatively easy. One barb from the catch runs to the barb on the valve cover that connects the vent hose to the MAS intake hose/pipe. With the hose connected to the barb on the catch can, route it as you wish to the front/right side of the valve cover. Remove the stock hose from the barb. Cut the hose from the catch can to the appropriate length and attach it to the barb on the valve cover

Now make the connection at the MAS hose/pipe. You can follow the hose you disconnected from the valve cover down to locate its position on the MAS hose/pipe (facing backwards just under the BOV) if it's not plainly obvious


All that needs to be done now is to run the hose from the MAS hose/pipe connection to the other barb of the catch can. Again, route the hose as you wish, leaving adequate clearance around the waterneck and lower radiator hose. Cut the hose to length and attach it to the barb on the catch.
When all hoses are connected, tie strap them to keep them in place and you are done!

 

^ Great post! Thanks... So is this more of an item to buy when you start making higher hp numbers? I use my Evo for mostly Daliy driving. Maybe 1 every 4-5 months do I go to the track.

 

i hope i helped

 

It helps keep your intake clean!

 

i view a catch can on the same level as having a turbo timer. its not going to give you hp but it does help in the long run.

 

works for me

 

So its a good idea but not needed right away?

 

^^ Yup. Be careful though, some catch cans aren't all they're cracked up to be.

If the inlet and outlet are close to each other and the inside of the can isn't baffled, that leaves a lot of opportunity for the blow-by to blow right through the can and into your intake (since it's sucking the air directly from the inlet to the outlet).

If you get one like this, you can stuff it with a Brillo Pad, but I would recommend something that's got the inlet on one end and the outlet at the opposite end, and baffles or Brillo pad will just increase the amount of blow-by you catch there.

 

I think it's more sustained, high rpm rather than high power. My car is nearly stock but after a few track events I have 5-10ml of oil in my trap. A cheap CH line trap with a glass frit works really well.

The hardest part about the oil catch can is finding a place to put it. I have mine right behind the batter wire tied to the strut tower brace. Temporarily until I install my intake. But I did notice that even after 1,000 miles my stock intake was covered with oil residue.

 

Thanks guys... I've been like the Weapon R catch can do to it inexpensive price and that it Evo specific. http://www.lancershop.com/customer/p...9&cat=0&page=1 Good buy: Yes or no?

 

weapon R is a very good choice i have it and so does my buddy. I drain it after ever oil change.
