catah can
 
Anybody with a good source for a oil catch can? How about someone that has built there own? Lets see what you guys are using. Philip

A930Rocket 02-23-2011 05:46 PM

Look at Summit or Jegs. They have several including one that fits the hose coming off the oil tank filler (that went to the air filter).

I can post a pix tomorrow.

I've made a few now. this one here is for my GLH turbo dodge. The second, not pictured yet is for the Porsche, after I removed the factory airbox. Instead of just putting filters on the end of the oil vent pipes I'm putting a small catch can on with a filter on the top. I may also change it from a filter to a fitting to attach
to the top of the air filter..pics soonhttp://forums.pelicanparts.com/uploa...1298552632.jpg

I've done quite a few of these, Peterson Fluids Systems makes nice cans. Proper crank ventilation commonly overlooked. In kit form, Jim Patrick of Patrick MS has a good deal going and specific to Porsche.

Serviceable with internal baffles, drain plugs and lightweight aluminum etc...

A930 Rocket; Thats the can I'm looking for. Any more info on where to source? I checked the links you mentioned, but to no avail. David, nice custom touch, really thinking outside of the box. Philip

boosted 89 02-24-2011 03:46 PM

Just made this the other day..It does not replace the one by the oil tank but is
used for 2 hoses that normally hook up to the factory airbox. Some people just put little filters on them but I figured I'd make something small but neat

Try searching for Moroso products at Summut and Jegs. It's not called a catch. can but something else. Overflow tank maybe?

Made this for my turbo 535is, but will be using on the 930.

1" hose connection
 
I have been looking for a tank with a 1" ID hose connection. I would like to not reduce the vent size from the oil tank. What is the ID of a #12 an fitting. Philip

A930Rocket 02-25-2011 08:09 AM

-12 is just under 1" as I measured mine, but it fits perfectly. No need to squeeze down the hose.

looks like jegs is beating summitt by about 4 bucks on the moroso

A930Rocket 02-25-2011 11:42 AM

Even with shipping they beat Summit by a couple of bucks.

AN fitting size
 
Going to a chart on the web, I see a 12 AN fitting has a inside dia of only 11/16. The oil tank breather hose on my car measures 1" inside dia. This is more than a 25% reduction in ID. I would like to find a can with at least a 1" connection. With the new breather assembly/turbo drip tank that am installing, the vent from the drip tank will not be hooked up further more eliminating yet another way for the oiling system to breath. Any input on this guys? Philip

I held a tape measure to mine. The outside of the threads are ~15/16. The ID is ~12/16.

I can take a picture tomorrow.

Yes, my mechanic also agrees with the 1" theory... without it, could cause pressure to build in crank case...

Here's the one I had made for mine...-16an from oil breather, -8an for turbo sumps, 2 extra -6an for future use and -8an drain to easily empty contents as needed

Did my homework, and figured this catch can had a good design with the baffles. Thanks Kraftday for the link. Lots of nice custom cans out there guys, but the nice weather will be here soon, and still have a few more projects on the list to get done. cheers Philiphttp://forums.pelicanparts.com/uploa...1299980751.jpg

spence88mph 03-13-2011 12:06 AM

Has anyone noticed crank case fumes are reduced or eliminated with a catch can? I read that you should stuff them with steel wool, it helps filter and separate the oil and air? My car just uses a k&n filter on the end of the hose and it really stinks out the cabin, I just can't see how a catch can will really help with that!?

I've wondered about this as well . . . if the catch can or "filter on hose" vents into the engine bay, wouldn't the engine fan draw the fumes in and then blow them through the cabin heating sysyem (as well as all over the engine itself)? Some past posters have said this is a problem and others have said it is not . . . go figure.

Glad you checked it out. Peterson is a great quality american suppler for the tanks. The Peterson can above works great too but since it is bit taller with that filter element on the top, it is not as flexible installation. With every oil service, the petcock valve on the bottom is easy access though. The German Cohline company supplies the OE cloth braided hose in the proper metric size.

If you wanted a super trick OE setup, I'd check these out..

Really nice and flexible set up there. Love those BMRS lines!

I was lead to believe that the original 930 AOS is a very good unit.

Have many 930 users found it to be inadequate?

My issue with all of these except the MANN unit is that they vent to atmosphere = nasty oil and fuel smells http://forums.pelicanparts.com/suppo...oilet_claw.gif[img]

philip j 03-15-2011 04:24 PM

fumes
 
Anyone else have this problem? If thats the case, the can could be vented down through the tin to open air. I can't see there being any more fumes than what would burn off your engine with the small leaks most of these cars have. Philip

kojo911 07-06-2011 04:11 PM

MyTurbo3.6,

Looks like you have two turbos. If your running a stockish 993tt set up, do you take the lines off the turbo sump breather and run them to your catch can? The stock 993tt is pretty complicated, I'd like to eliminate the turbo sump breather to intake/throttle body and just vent them with the catch can I'm already using for the crank case.

Thanks.

E-man930 07-06-2011 04:25 PM

I picked up my carbon one for cheap of eGhey. (internal baffles / drain / seperate vent chamber) Lots of nice race bits on there if you take your time.

Yes, I vent from the factory 993TT sump tanks to the catch can shown above.

krasuskyp 07-07-2011 05:05 AM

Thanks for posting up all the options, links etc.

I'm tiring of my filtered vent line misting the upper / right corner of my motor with oil - getting old, esp as I've got a pretty damn clean engine bay otherwise.

1/4" of inlet ID loss aside, that Moroso one @ Jegs looks like it'll do the trick - $80's certainly better than mid $200's for that Peterson unit... yikes.

Regarding fumes - I get an occassional whiff here / there, nothing bothersome. Notice it's worst when sitting w/ the windows closed for a few weeks, but even then it's not so overt to be annoying.

So how often are yous boys finding you have to empty them thar things anyway??? Curious to set expectation, measure comparitively...

JFairman 07-07-2011 06:16 AM

Your '87 came with a black plastic catch can mounted behind the oil tank and it has a hose on the bottom that drains back into the oil tank below the engine tin.
It origonally vents blowby gases back into the aircleaner.

Venting those gasses into the engine bay through a little k&n air filter is a bad idea because if you use heat in cool weather all the hot air that comes into the cabin came from the engine fan and the engine fan is sucking in the blowby gasses from the k&n vent in the engine bay along with air.
Blowby fumes are like exhaust gas, definately not healthy and stinks.

You can run a hose from the breather tank through the hole in the negine tin for the air pump hose below it and let it vent to air a few inches below.

kojo911 07-07-2011 07:25 AM

My3.6,

Just so I'm clear, your going directly from the sump breathers to the catch can. Not "t"ing off w/ the throttle body. That is no vacuum in the sump breather lines. Sorry for the redundant question, thanks for your patients.

Ken

krasuskyp 07-07-2011 10:42 AM

Thanks Jim - it's my oil tank breather vents to the filter which is what weeps. My OE can / vent is still as originally fit.
