Thanks for the tag.
You guys know me. I don't like changing something that ain't broke, even if it broke (once) ![]() I have only seen one person say they had to modify the housing so it's a little hit or miss. but Most everyone seems happy with it. i'm waiting for more data before i change from oem. |

Aluminium oil filter housing won't change anything as the seals will remain the same : plastic.
For the people who will tell me : well, the aluminium won't broke/crack at least, I'll answer : don't over torque your filter, that's all. People just get and OFH in aluminium hoping that it will solve their problem : that will not, that won't change anything at all. |

I upgraded to aluminum one. If youre gonna keep the car , id go aluminum just to avoid replacing it again. Yes the little gaskets could go. In cali it gets really hot , so to avoid cracking the housing again i went aluminum. i seen plastic one go out 30k 40k 60 70k all depends on the heating cycles. While at it replaced all the coolant lines down there, and aluminum connector that connects to the head

As someone who has worked as a designer in various industries (including automotive), I wouldn’t dismiss “plastic” parts out of hand. The gaskets very well may be the true culprit. If a high number of housings are failing, that’s one thing. But if the leaks are occurring due to gaskets, upgrading to aluminum is rather pointless, as some have already pointed out.

The lower coolant orifice broke where the seal sits. My metal housing is working fine. I have experienced no heat soak from the block to the exchanger that affects any of the temps in my logs (IAT, Oil, etc)... So far, no issues. I guess I'll pull this thread up in another 90K miles. ![]() |

Mine went out the same way as sighter2.0 posted, almost same exact piece cracked and caused coolant leak. Fortunately enough, water pump weep hole also show signs of leakage. Both of these were dealt with at the same time at around 64k miles.
I also did the coolant flange upgrade to aluminum one, but bought the flange that has a built-in o-ring gutter. There are a bunch of "flat flange" versions of the coolant return junction, I couldn't trust those so I found the correct flange so I can use the OEM O-ring and things went well. On OFGH replacement into the aluminum version, I'm at about a year after the replacement now, got 88k miles on the clock, and no issues at all. I also did MHD Stage 2+ tune after the full coolant/oil piping refresh. So yeah, the aluminum housing held up well. Few small tweaks I did were that I went with OEM rubber gaskets, OEM bolts, OEM oil cooler unit, and I swapped out the built-in oil check valve from the plastic OEM unit simply because I only trust that aluminum cast housing, everything else I can't help but suspect the quality and the risk involved. Anyway, job took me a full Saturday to take things out, the whole Sunday to put things back along with VRSF CP and DP, and a whole radiator since I did accidentally crack the inlet hose during the big job. The radiator has plastic junctions which are very easy to crack. So if you're doing a bunch of work altogether at the same time, be careful not to proturberate the radiator joints too hard; they crack easily.

Just did a B38 engine - 100k mikes. Exact same failure as in picture. That plastic bit just came away.
The gaskets are not the issue here, the plastic disintegrates at the gasket junctions, so if I ever have to do this again I'll source an aluminium housing with OEM gaskets👍 |

Did the job a while back, so I can't really recall unless I get back on it again. If/when I get to do it again, I'll try to post it up here, that is, if no one else had given an answer by then. But I don't reckon it be too difficult.

Don’t remember the brand and I had to just guess which one to buy on Amazon when I was looking at replacing mine. At that time there were only 5-6 reviews and not that insightful so I took a big gamble on mine and ended up just fine. I reckon they are all pretty much made by the same plant, just distributed by different channels. So as long as you’re getting the aluminum one, it’s already an upgrade from the OEM plastic.

340i housing replacement
I'm looking to do this soon with an aluminum housing as preventative maintenance since I drive a lot and rack up miles quickly. I have a 2016 340i with ~77k miles. Does anyone have a recommendation on specific companies to buy the housing from? I'm also looking for a shop in the Hudson Valley area in NY.
