| Post subject: | Simple Vent Tube for CCV |
I'm wondering if there is any reason not to do a simple vent tube aimed down towards the ground on our CRD's? My Dodge has one, along with most all other non emission controlled (pre '07) diesels. Is there some kind of electronic signal or sensor that must be disabled? Other than having a few oil drops on the paint and rear hatch, which I'm used to on the Dodge anyways, I can't think of any downsides to something this simple. |

That is often referred to as the Elephant Hose Mod on the board. It has been done. The CRD gives off a lot of vapor. In cooler weather it can really give off a noticeable cloud when stopped at a light. Especially at night. Some have found the odor offensive too. And, of course, it is illegal for on highway use. Some have called it active rustproofing.

How is it illegal, if all 5.9 Dodge's have a simple down tube for the CCV??? |

The Jeep is in a different emissions category than a 3/4 ton truck. Changing the Jeep would be modification of an emissions control device to defeat its intended purpose I suppose. Never said it was fair, and I'm not preaching. It is just something to think about if considering this mod. Around here it wouldn't be a problem normally. |

'63 was the year that cars had to have the CCV. It was the end all solution to LA Smog. Diesels got a few more years before the CCV was imposed, but it came along. GMCTD did not like the oil spots on the driveway and went to the Provert. I was inspired by the TDI Wagonguy oil separator and made one for my CRD that works. http://picasaweb.google.com/warp2diesel ... #slideshow |

My rubber slide on cap on the oil drain line will come off and puke all the oil onto the ground before any engine seals blow out for now. Pressure relief will get intstalled later when I run the plumbing to the turbo drain line. |

| Post subject: | In-line filter |
I saw an in-line filter at the hardware store that would be used in a garden hose sprinkler system to filter the jets from any dirt. It has a 3/4 inlet and outlet and a plastic mesh type filter inside. I thought of trying this filter in line and perhaps stuffing some steel wool or similar as a trapping medium. What are your thoughts on this or in line filters in general for CCV. |

That would be closed venting system, the only problem is that it would require periodic cleaning as there isn't really an area for the oil to collect. Then i would be concerned that the filter medium will clog up and cause pressure in the crankcase. |

| Post subject: | Provert sells their bells and wistles |
Mann supplies components that are used in large truck fleets and if a fleet manager is going to spend money on an extra attachment, it better protect him under all circumstances. Compared to the home made Provet inspired by the TDI Wagonguy, it ihas over kill capacity for a 2.8L engine and concerns of clogging up and building up crankcase pressure are border line paranoia. Considering that Jeep has no pressure relief other than no hose clamp and a wimpy CCV hose, Provert is almost as paranoid as worrying about your Wife standing you up on a dinner date where she does not have to cook. |

and quite a bit of vapour from underneath the vehicle aspecially at idle. Perhaps i should try these relatively cheapish plastic in line filters but use 1 in the outlet and 1 in the inlet. they would be installed horizontally as they are long and narrow with the inlet and outlet on either side. I hate to jump in on this because usually when I do I am laughed at,made fun of, called names ect, ect. But here it goes. MILLIONS of Ford/International Power Stroke Diesel engines over the years have used this same CCV set up with no ill affects except oily residue on the cac tube connections. People with hundreds of thousands of miles have removed their air coolers to find ounces of oil---Not quarts. I have never heard of an intake being clogged such as the VW TDI will. Time will tell whether our VM 2.8 will be clogged solid because of the CCV, but it seems that is unique to VW. Upgraded cac hoses may be the only upgrade needed here. OK,,, Flame suit on |

I did the CCV mod with the in line filter that cost about 9 dollars stuffed with steel wool and ran a 90 degree elbow to connect with the outlet. Neat fit right on top of the valve cover. I used clear reinforced piping so i can monitor the effectiveness of the filter. Will require frequent cleaning but i'm happy with that. The gumph that i cleaned off at the FCV when removing the butterfly and the oil in the hoses made we realise how ineffective the stock CCV is. Next job now is to clean the intercooler. |

My EHM is about 10 feet of tube connected to the CCV puck and routed up(so the oil runs back into the valve cover then the hose dows down to the frame rail. I have an open hose fith no filter on it at all. The othe tube I put a plumbing dummy end cap on it to plug it up. seems to work nicely and I am keeping my intake clean and that is the idea. |

Am i correct in saying then that open venting is okay and that there will be no long term engine damage due to the lack of crankcase vapour or vacuum or pressure. |
