I believe that it's a check valve to keep the filter from draining when the engine is off. That is because the oil filter is somewhat sideways when installed. It helps the oil pressure to build faster when restarted. I would stick with the oil filter with the check valve. |

Be aware that most filter manufacturers do this now... you want to look for both a check valve and the best filtration possible (smallest micron). NAPA Gold filters, Purolator, Wix, etc... are all great filters with these features. I say this because my wife stopped by an auto parts store that tried to sell her some stupid expensive Fram "special model" that had weaker filtering charecteristics than good ol' NAPA Gold's. |

I just love technical talk! 
Just joshing. I'd stick with Purolator PureOne filters. |

that thingy is there for one singular engine that has/had an oil drain back issue, it won't help or hurt the CRD engine. keep in mind the micron ratings is just one measure of a quality filter, every oil filter in the world will bypass oil when the engine is cold so its not even filtered anyway. the design of this valve is critically important so that it does not bypass once the engine is warmed up. many high quality filters have bypass valves that are metal on metal, which will leak a bit. but this is splitting hairs. when it comes down to it the oil filter is not really all that important, most of them meet the required SAE specs, and that really is all you need if your following normal service intervals. |

The oem filter works good and is just as cheap as a napa gold. Plus you know the bypass works at the corrrect psi. |

You mean NAPA has DOUBLED the price of their oil filters to $15? That's what the dealer charges for a oem filter around here. A CRD-specific Purolator is $7.50 at Advance (even has the "thingy" in top). |

Oh please, buy a 6 pack on e-bay for less than 6 bucks a filter. I never would have guessed your dealer tried to bend you over for a single oem oil filter. |

My dealer doesn't even stock them. If I go a ways to another dealer he wants $15. Just ordered six official mopar units off the internet $6.16 each with shipping. There are probably better units but those would definitely cost more. |

I've never seen Mopar Liberty CRD oil filters on Ebay... fuel filters yah, but not oil. Mopar filters are just re-badged Champion, Fram, etc..., just like the fuel filters. No idea who makes them for the CRD, but I will continue to run Wix, Napa, and Purolator filters in all my vehicles. Read too many reviews demonstrating the superiority of those brands to the el cheapo filters that usually make up OEM options. |

CRD filter is made in Italy so I kinda doubt the champion lab theory. I'm not saying it's the best filter out there. I know it works for me(backed up by uoa) and it is comparably priced to known good filters. |

I run a Purolator in mine since it matches the size of the stock one. The Fram is quite a bit shorter than the stocker. |

What singular engine? some 4 cylinder, don't remember the make or model. but the double anti-drain valve serves no purpose but for this engine. |

For those who wanted to know but didn’t ask. The following oil filters will fit our CRD’s. First, the one for the CRD is a FRAM PH8316, or NAPA FIL1516. For a full size oil filter, the one off of a Ford Truck with a 302 V8 will also fit, FRAM PH8A, or NAPA FIL1515. For a full size half-length one, try one off of a 1991 Jeep Wrangler with a 4.0 in it, FRAM PH16, or NAPA FIL1085. All the above filters have the same screw-on threads, same sealing surface. The full size ones have more capacity so hopefully more surface area for the filtering media. Note that the full size ones are a little “fatter” but shouldn’t be a problem. The length of the full size bothers me, but if something is going to hit it, I guess it doesn’t matter what’s there, it will get hit. As for me, I will NOT use a FRAM. Perhaps a WIX or NAPA Gold. Anyone using the full size filter on their CRD? |

I just cut open a Mopar CRD filter and I must say I am kind of impressed with how rugged the design is. I have 2K left on the oil change in my CRD now, at which time I will cut open the Purolator Premium Plus (white filter) and compare. I have one more of Purolator Premium Plus to use up and then I will get a Purolator Pure One (blue filter) and put it on and then cut it open. I hate to buy a new filter and cut it open, what can I say, I am cheap

I'm running an Amsoil EaO-26, about as full size as you can get - 1/2" larger diameter and almost 1 1/2" longer than stock. Screws on without any problem and still clears the skidplate. Added nearly 1/2 quart to oil capacity. Little thing I've tumbled onto with oil filters - standard thread size = standard gasket size. Any oil filter that has the same 3/4-16 thread as ours will have the same size gasket, regardless of outer physical dimensions. |

Is there something that the smaller EaO-34 is not doing that you feel the need to use a larger filter? |

You do realize you just necro-posted a topic that was nearing 5 years without a reply, yes? Your best bet is to go to http://www.hotrodoil.com and solicit a dealer's advice. |
