Oil Catch Can/CVV delete mod doityourself

[derbo]

A catch can is always better that recirculating the fumes and gunk back into the intake manifold. It would seem to me as purely a part of the emissions components. I am not sure the effects of its remove has on tailpipe emissions but I know visually it will fail. I should try and test it out with it removed on the smog dyno to see what it the tailpipe numbers are.

I've been a gearhead for years, but never heard the term "smog dyno" before. I suppose it is because emissions isn't an issue where I live. Sounds pretty cool. I'd be interested in the numbers.

One of the most intriguing things for me is, the liquid goop I am catching in the cast must have been making it into my oil through the CVV's return line. How do these engines live so long with all that crap running back down the dipstick tube?

Just a thought but I wonder what kinda crap you would find in the can if you ran some seafoam through the motor.

IDK because the Blackstone oil analysis say it's a good system based on data. .

Funny you should ask. I have another thread about sticking oil rings, in it I describe my woes. One thing I did was run Marvel Mystery Oil and currently I have a mix of dino oil, ATF and seafoam. What I noticed with the MMO was more "crap" and it was black vs the whiteish colored stuff. Here is a pic, I thinned it some to get it to pour from the can, but you can clearly see the chunks of "stuff" in there. Scary!

I am sure it is a good system, but this crap I am catching had to be going somewhere, no?

You couldn't post this just a couple of days ago, could you? lol
I literally just replaced the CCV... ugh.

If it makes you feel better, so had I. My CVV has roughly 300 miles on it, just sitting in my garage staring at me. Stupid plastic POS. Maybe I will blow it up come New Years when the fireworks stands open back up!

I just showed this thread to a BMW tech friend of mine. His question is: what did you do with the remaining 3 openings?
The CCV attaches to the intake in 2 different locations and also connects to the dip stick tube.

He also makes the statement that the increased pressure on the piston rings will wear out the piston rings prematurely.

California Smog Emission test involves a visual test, 15mph dyno emission test and a 25mph emission test. No fun at all since a car may pass idle smog emission test but at 25mph it may fail. :X
