I ran across this video today. Nice aluminum part, inexpensive, it has a dipstick to see if it’s full. Comes with a few different brackets. It doesn’t “fit” a 6.0 powered F250 according to Amazon but I’m sure I could rig it up. What do you guys think? Will it work ok or am I missing something? Maybe there’s a better choice?

 

Lol. I was just looking at this on my Ebay account as one of my saved items. The one I'm looking at is 3/4 fittings and has a drain with a sight tube. Best part it's only 25 bux.

Plug the hole in the intake and run a 1” heater hose from the CCV to the frame rail. Cheap, simple, no drip, no oil vapor going into the intake.

 

I did exactly that 90K miles ago. I ran it along driver frame rail and terminates near fuel tank.
It is oily at the end and sometimes smokey .
On one hand im glad im not putting all that oily vapor into the intake but is my situation normal?
Just curious as im thinking about adding a cheap catch can.

 

Yes, that’s the Crank Case Vent, just oil vapor from the crank case. Mine is short, stopped it by the transfer case. I think I have 12k on it, no drip but I made a rise by the degas bottle before the hose drops to the frame.

 

I think he is asking "At what point of visual appearance does it become an indication of excessive blow-by".

It doesn't sound like yours is in that category, but if you were worried about it, I would take it in and have it actually tested. There is a special tool to measure the crankcase pressure.

 

Okay Rusty this is your fault if this blows up. But really I got it just for ****s and giggles.
It was only $37 after tax.

P.S. I think that guy sounds like some used car sales man.That tells me one thing. RUN!

 

I think Rusty’s is going to be small on the ports, Pete’s might be OK. It will be interesting.

 

Sean, yup Scotty is a trip. The little pictures he puts up while he’s talking are hilarious sometimes. He’s right most of the time though and a lot of his posts are about vehicles I’ll probably never work on so I don’t check him out a lot, just when the subject sounds interesting. But he’s a fun dude if you can get past all the arm waving stuff. I’ve looked in the Jeg’s Catalog and others, I just liked the looks of this one. Kinda small, I’m sure I can find a place for it and the little dipstick is too cool. The one 87crewdually posted a link to (thanks) actually looks like a better one and for a few bucks less but it’s larger. I’m gonna give this little one a shot also.

Jack, in the picture there are several more fittings and an adapter of some sort, for sure that 3/8 isn’t going to be big enough but if there isn’t anything larger with it I’ll just get something locally. Heck, I can even drill and tap the housing if it comes to that (and there is enough meat there). I don’t think I’ll use the dishwasher hose either, lol. I imagine that stuff will be hard as a rock in a year.

Any thoughts on his description of injector placement/carbon buildup as it relates to our diesels?

 

I have been reviewing my orifice calculations for the blow-by testing aparatus. The orifice itself is around 1/2 an inch. I tell ya, I would want at least 1" hose and fittings. No telling what the pressure drop of the internals are going to be on the small "catch-cans".

 

Hmm. If it turns out to be a significant restriction, I’m guessing that will raise pressure inside the crankcase and promote leaking seals and gaskets. I was thinking more about the fittings themselves and not so much about possible internal restrictions. I’d have to have one in my hand to even guess. From the pictures it looks like a 3/4 fitting may be possible as far as that part goes. Is the factory hose 1in? I haven’t measured but I was thinking it was maybe 5/8 or so (ID).

Hey Sean, when yours comes in can you take some pictures of how the inside is made? I know, kinda tacky. Lol

 

It has been too long - can't recall the factory hose size. If it is 5/8 (or even 1/2), just remember that there is only an inch or two of it. Way different than multiple feet.

 

True...I guess I’ll have to study on it. I was thinking with the small size, I could find a place for it under the hood, keep the hoses fairly short, wouldn’t expect for it to fill up quickly and it would be easy to check... looks there may have to be a compromise or more modification than I was expecting.

the other larger ones I’ve seen look like they would need to mounted under the truck somewhere.

 

You know I will.

Well it it tunes out to be smaller than neede one could always do a parallel install.

One thing I have had in the back of my mind is to do the oil separation like the Allison A250 turbine engine does it.
That engine uses a spinning gear between the gear box and the vent. The oil/air mixture is spun and the oil being
heavier is thrown to the outer section of the ger where the return ports are. The air that goes down the center is
cleared of the oil and allow to exit.

I have some photos around here somewhere of that assembly.

 

My intention (if I ever do it) was to order the one I posted and mount it close to the engine. Then I was going to run the rocker cover port hose to the catch can. Then out of the catch can back to the intake. I was going to use the clear vinyl hose because if I remember right the 3/4 inside diameter gives you the correct outside diameter for the intake and breather holes. I just want rid of the oil vapor. I like the idea of the turbo drawing the crankcase pressure.
