Bypass oil filter
Has anyone of you thought of installing a bypass oil filter in the 335d? I remember reports from Germany where people were running engines 100,000km on a single oil change. They would regularly change oil filter and bypass filter and top off the oil which replenishes the additives.
I'm not thinking of copying that but wondered if it would make sense to try to get carbon deposits out of the oil using a bypass filter. What's your take on that? Here's a link to the AMS universal single remote bypass filtration system: http://www.amsoil.com/shop/by-produc...?code=BMK21-EA There should be cheaper options around though. |

A co-worker did this on his commuter car (Yaris) he only changed his oil every 25K, (synthetic) and it had about 215K miles on it before some drunk driver hit him. I'm sure he'd still be driving the piss out of it if that didn't happen.

Great idea! OTR Trucks as well as light/medium duty trucks have been using this type of system for quite some time. I have often thought of putting one of these on my diesel trucks(s). Would be a great way to keep our d's even healthier Here is a link from Blackstone Labs: http://www.blackstone-labs.com/by-pa...filtration.php |

I am in the half way thru it.
The hard part is to find adapter from M12 thread into 1/8npt and M12 back, there are not much clearance for that? and it needs a special adapter. |

Sweet! Nice solution on the exit reentry through the filler cap. I didn't like the suggested solution of drilling a self-tapping port into the oil sump.
Where is your entry port / where is the oil coming from? |

Actually i have order a insert into filler cap, as it is leaking right now.
The entry port is from the bottom of oil filter housing, where the oil pressure switch is located. |

I have got a kit with a filter from ebay, from a guy who bought it and never have installed.
So i have a huge filter, and it takes more likely another two quarts if no more. |

Nice job and thanks for sharing. You have motivated me. Here's an installation in a 325i. Same basic configuration, with discharge to the oil filler cap. http://www.amsoil.com/bypassfilters/..._Fleschner.pdf Last edited by DWR; 09-02-2015 at 10:11 AM.. |

Did some research that I thought everyone might be interested in. Here’s a link to a Baldwin bypass filter and filter base, that is much more affordable. http://www.adiesel.com/search.php
These filters are available at Grainger for $10.48. Performance is 2 micron nominal, 12 micron absolute, apparently the same as Amsoil. |

Sorry about the link folks. Just realized it brings you to site search. The filter is B164 and the base is OB1305. If you use the link's search with "B164", you will see 3 different size filters and the base. Thread on the oil pressure switch is M12 X 1.5 The filter base is for filters with 5/8-18 thread The oil input and out ports are 1/8 NPT Hope that makes it easier for all who would like to try this |

Can you share what the issue is? Threads, length?
I thought you said "in amsoil they have more than you will need." Now, you are saying you made your own adaptor. Please clarify, thanks. |
