My new CCV system...Version 3.0 - Page 9

tadc · November 19th, 2009, 11:33

The idea is to condense oil vapor out of the CCV system before it makes it into the intake, based on the theory that the intake clogging happens due to hot, sooty EGR gasses and cool, oily CCV gasses combining and forming 'sludge'.

So theoretically, it helps prevent intake clogging. There is no performance benefit, and I think it's not 100% proven that this will prevent intake clogging. I've recently heard a competing theory that it's really bad MAF performance that results in intake clogging...

Last, I dunno if PDs suffer from this issue anyway.

Can I just buy like a K&N Crankcase Vent Filter(62-1517 or something similar) and attach it to the engine and the L shape hose router back to the intake? would it give me a code?

Yes PD's suffer but not as bad. I don't know how a MAF would make the oil go from the engine to the intake more. Yes some vent to atmosphere and just put a plug into the intake so it is like a gasser vent. Some have them ice up in the winter so you have to watch how you do it or oil starts coming out the dipstick.

2P133 no longer available from Grainger.

2114130 is the part # at Tractor Supply Co. for the 1" poly strainer.

Here is a link to the racor closed CCV filter system. It's a bit expensive for my taste but should serve a good example of what our homebrew filters should be doing, I guess.

Anybody make use of anything like this?

Land Rover part number ERR1471

Cyclone action seems like it would work very well. Looks like it may take a bit of creativity to adapt, but may be worth the effort.

To me cyclone implies high flow which is absent in the TDI CCV. It isn't a flow through system like most gas PVC systems.

Not that they flow that much air either.

You are correct, the cyclone separator needs a minimum amount of flow to work properly. The internal dimensions are set so that they will be functional at different flow rates. Looks like these are used on the defender 200 and 300 TDI. The 200 TDI at least is 2.5L. It has a mechanical vacuum pump that is vented to the crancase so that is about the same as ours. Not sure if the reduced flow from our 1.9L will still allow proper functionality. My gut says it will probably do just fine, and most likely better than stock setup. I might see if I can source one to play with.

The ProVent CCV system outside looks similar in design to the 200 TDI Cyclone mentioned above. Wonder if it uses Cyclone separation action too?

Another example of cyclone separation....Looks like these types would be readily available at the junk yard for cheap...

I'm planning to run to the local junkyard tomorrow to scour the yard for a BMW that might have a cyclone oil separator. I made some notes as far as sizes on my CCV pieces and oil dipstick that I will have to tap into so that I can gather most of the parts needed when I'm there. I also made some notes on engine sizing vs vehicle style(ie 535i etc) so I will know what the displacement of the engine is. I'm looking for a cyclone separator from the lowest displacement engine I can find. With any luck I will be able to find some parts, and more importantly get something functional put together that will really help me.

Went to the local junkyard on Saturday, and acquired some various pieces for about $10.00 I didn't find a BMW Cyclonic air/oil separator like I wanted, but found enough stuff to create my own. I assembled it on Saturday, and installed it on Sunday. I have about 400 miles on it so far, and it seems to work very well. The first 80 miles(in town) or so I didn't notice anything that had started to give evidence that it was collecting. After tonights journey to pick up my father in law at the Orlando airport I had a good chance to give it a work out. Looks like I am collecting liquid oil on the Stainless Steel funnel that helps to form the cyclone in the unit. The bottom of the cyclonic unit(Drain) is "T" ed through a 3/8" rubber hose into the oil dipstick to return any collected oil to the sump. Now that I know it shows the potential to operate, I will have to install a measured collection system so I can quantify it's effectiveness.

I read in post 1 that wingnut is now using Kayakkermit's setup, and i found the PDF, but it doesn't list what parts were used. I've tried searching, but can't find them, can anybody point me in the right direction for the list of parts?

yatzee · May 19th, 2012, 14:52

it's an agricultural Strainer. Without your location listed in your profile, we can't tell you when to find 1.
