Navy, glad to see you are up and about and filling these pages with knowledge. Now, from the original thread: Quote:
I really think that we should go back to the original thread with the oil filter discussion. Clearly, two threads results in lost information for everyone. |

OK, which one is the first thread?
Changed my oil today. I put in a MANN filter, labled in red computer printed ink Product of Germany or something like that. It looked not much like the MANN I saw last week that said Made in Checz-something. Go figure. Neither looked like the filter I had in the car from the last oil change, which was physicaly stamped into the top of the case Made In Germany. Your guess is as good as mine. I do know looking at the holes in the bypass section I saw nothing but white, very bright clean white, in the one I just installed. Eh, what can you do. I'll try and remember to look for the oldest OEM looking filter I can find at work, but it may take me a bit to get around to it.

My thoughts about the OE is the same as for OEM, that's why I have a NAPA/Wix filter in the 240D & the VW. What really has me worried now is what the devil does my secondary filter have inside for filter media. My guess cheapest crap available, as mine is OEM. I have a spare FF on the bench I guess I could rip it apart and see. If I had any sense I would just get a NAPA/Wix fuel filter and be done with the worry.

The problem with just stuffing loose cotton in the filter is the oil will crate tunnels through the cotton and not really do any filtering. The woven cotton filter string would probably have filter about 50 to 75 micron size particle and the paper portion about 20 to 30 micron. With just the stuffed raw cotton in the upper section withe the paper holding it in shpe in the canister, that would mean as soon as the oil backs up at the lower paper filter section it would flow through and out the by pass section without and real filtering, other then what wraps around the upper cotton section holding the cotton inside the filter. That's why a some of here has decided to stay away from the cheap outsourced products made in India and buy US made Wix, NAPA and such filters using pleated paper filter s in the upper section.

The picture on page 7 is the oil filter from my 240D. I cut it openafter a short use period. The picture below mine of the Autozone filter is how they use to be made from the looks of the picture. Page 7

The issue of cotton gin waste has been found in OE, Hengst, and Mann filters.
May seem surprising, but it is true. Read the entire tread. |

Which Filters?

I am cutting one of each open tomorrow and I WILL post what I find. |

Rusty,
The concern is the bypass section of the filter, where we would expect very tightly packed, and clean, cotton or other material. Instead, there has been loosely filled gotton gin waste, bug parts and other material that would not stop a grain of sand. Certainly not the 10 microns that would be expected of a bypass filter. PLEASE, PLEASE, CAN WE GO BACK TO THE ORIGINAL THREAD? |

If we could settle on a particular brand (I think it's down to Baldwin, WIX and ?) maybe Rusty could offer a group buy?
I ttried to find Baldwin dealer that sells a filter for the OM603 but was unsuccessful. I hate to say it, but they may make great filters (for other than MB) but if they can't get the right one to market, they aren't in business to serve me. I was leaving WIX as a last resort after hearing that some of their filters were made in India. I'd rather buy Baldwin but have to special order from a tractor supplier in another county, they make it hard to do business at least in Metro SF Bay Area.

With the loose packed cotton waste packed in the upper section, I'll bet the oil isn't filtered more then about 70 micron to 100 micron in the upper by-pass section.

Thanks Navy,
If that is how it works, then I did have it backwards. The bypass section on the oil filter is used when the main section cannot provide sufficient volume to maintain pressure, correct? What controls the flow between the two sections? At what point does the bypass section get oil? On a brand new filter, right out of the box? Does it get more oil, as the main section is slowly accumulating dirt and debris over time? Any ideas on this? |

Oh Navy,
I think you might be trying to trick me.
I'm still trying to get Baldwin to respond with technical data. So far, without success. |
