Topic: Needed - Oil Catch Can Install Procedures

[spartan]

I've decided a catch can is a good idea, but before I purchase one on e-bay I wonder if any of those who have installed one can post up some procedures for the Kappas.   Some questions I have aside from the procedures are:

- What are the sizes of the fittings on the two 2.0L engine locations on which the two hoses connect?  I suppose I would need step-up or down fittings depending on the can I buy (and its fittings) but if I can understand this maybe I can buy one that is the right size to being with.

- The hoses that come with many of these look like they would melt around the turbo.  What size and type of hoses should be bought or are they ok?

I used 5/16th's hose all around, then i used a 5/16th's barb fitting with some electrical tape so it would seal tightly inside the steel braided line.
Best i could find was fuel line hose, but some parts stores might carry transmission oil cooler hose.

Shabby,

    Very helpful.  Just to be clear, you used 2 5/16ths barb fittings on the hose attachments to the engine points, correct?  Thanks.

Wait, I thought the catch can was suppose to go between the PCV valve and the intake? (the other steel-braided line in the pictures...)

I used just one to the steel braided line, the turbo has its own fitting once you manage to disconnect the steel braided line.

The line with the pcv valve draws in fresh air into the engine, the other line spews out oil vapor.

[spartan]

Ok.  I got it - went out to the car to orient myself.  I need to disconnect the braided line from the turbo and swing it around to whatever direction I put the can, then connect the other hose to the turbo location just vacated, and run that second hose to the can.  The line with the PCV is never involved...it stays connected to the air intake.  Yeah, this looks like a very good idea.

Great pics Shabby.  Appreciate the details.  I have to think this would increase performance a small bit since one will no longer be burning small amounts of motor oil.

[Uranium-238]

FYI-When (not if) the PCV dies it'll dump oil into the intake just as easily as the other line. Been there, done that, got the T-shirt.

[spartan]

I don't follow.

[Uranium-238]

...The PC valve died on my car, and as a result it was dumping small amounts of oil into my intake.

[Kelu]

Wow, I thought OCC should be mounted between PCV valve and intake pipe.

[shabby]

Wow, I thought OCC should be mounted between PCV valve and intake pipe.

The pcv valve is a one way valve, i guess if it fails it might dump oil back into the intake, but until it does it won't pass any oil.

[Kelu]

Good to know, thank you for sharing shabby

[kennysabarese]

is there much a difference between fuel line and trans line?

[spartan]

Advance Auto has 5/16 transmission cooler hose in bulk in the back - bought 5 feet for about $10.  It may not matter but it should hold up to heat better than fuel hose.  Also...FYI..Redline water wetter is on sale til the end of the month for $2 off.

Shabby,
    Which catch can did you buy?  I guess it came with 3/8 or 5/16 fittings on the can?  Thanks again!

[kennysabarese]

I think I bought the same can as shabby:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=220626618175&viewitem=&sspagename=STRK%3AMEWNX%3AIT

40 bucks shipped. Got it quickly. It came with some clear hoses.

[spartan]

Oh Vendors,

    This seems like a great opportunity to offer a simple standardized package for the Kappas.

 

[kennysabarese]

With all the right connectors, directions and stuff yeah this would be great and you'd sell a ton of them if it was $50 bucks or so.

[shabby]

Shabby,

The one that kenny posted looks identical, mine came with 5/16 and what looks like 1/2 fittings.

[IBDRINKEN]

i think i spent to much on mine

From what I have read maybe not, depends on how it is installed. If the PCV hose is left intact, yes you are at overkill, if you route the PCV through the catch can and then back to the valve cover, in theory, without some kind of baffle it can suck the oil fumes back into the crank case being worse than the stock system, so there are some variables.

By the way this is why they seem to be failing on the 2.0
"The PCV valve also functions as a check valve to prevent
  intake manifold flow from reversing back into the crankcase when there is a
  backfire, or during periods of high manifold pressure (boost) during forced induction
  by turbocharger or supercharger."

I think the factory PCV can't handle the pressure.

[DeepBlueGXP]

I agree, with the higher pressures of the aftermarket tune, it probably can't handle the pressures.  Perhaps a oil catch can will prevent the oil from being sucked into the intake.

[Gentleman Jack]

what about an upgraded PCV valve?  Stronger spring?  Perhaps not available?  DBG, after changing ChuckDocs, were you able to see if the valve can be disassembled?  Perhaps we just need to try a few different spring rates?

[DeepBlueGXP]

We haven't changed it yet, chuckdoc ordered it Monday.  I did try to clean the part.
