That hose went to pieces on me too - and I was down for a couple of days waiting on the part too. That was on my last e92. When I have to do this on my new one, I'll definitely make sure I have an e10 wrench. Thanks for that tip.

Sorry I did a lot of online resarch on the N55 oil filter housing gasket DIY and as my first time reading this thread I must say I've not heard of any of these"priming" requirements that you guys are joking about....
Quote:
I thought opening the oil filter cap allowed most of the fluids to drain out the housing BEFORE opening the filter housing. "monitor the oil pressure"? I'm sorry how? Quote:
Only time I primed my fuel system was when I replaced my fuel filter on my E36 318i.

You're right that an OFHG is really no different than changing an oil filter and it doesn't make much sense. It's not like an OFHG is actually draining the oil galley from the housing to the oil pump, or, bleeding the oil pump dry, but, who knows why else these cars might have seized after having the OFHG serviced... One theory is aerated oil. |

So forgive my ignorance but I must ask if this is specific only to the N55 in the E9x cars! I've seen the DIY done on numerous N55 F30s and other N55 BMWs without any priming done or engine seizing after issues. Quote:

N54: https://www.reddit.com/r/E90/comment...ay_on_the_way/ https://www.e90post.com/forums/showthread.php?t=1554479 https://www.1addicts.com/forums/show....php?t=1537202 https://www.bimmerfest.com/forums/ar.../t-953140.html https://x3.xbimmers.com/forums/showthread.php?t=1582839 Seems more common on N55s but in reality I just think a lot of N54 owners aren't posting up failures, going to dealers, or actively participating on forums as much as those cars age. They are still posting up failures in Facebook groups on the regular though... Used N54 is so cheap that they just swap in new engines rather then obsess over what went wrong like someone might do with a 2013+ N55 they still owe 20k on. Quote:
Priming the oil system involves cranking an engine WITHOUT starting it. How do you do that? Multiple methods were posted, but basically you disable fuel injection. No one said to "prime the fuel system" so not sure what you're referring to... |

uh yeah....um I didn't see these threads before. This is serious. I just spent the last four hours reading threads at various forums for 1 series/X5s/X3s/E9x cars regarding engine seizure after maintenance work was done to engine primarily the OFHG service.
This is definitely tied to vehicles with the same N55 engines that are in 2011 E9x cars! https://www.e90post.com/forums/showt...1554479&page=7 https://www.e90post.com/forums/showthread.php?t=1565205 I apologize for my ignorance but I'm still dumbfounded how I've been doing research on my OFHG for the last two years off and on and last three months intensely and never once heard of this connection between OFHG and total Engine Destruction!

Keep in mind there is probably 1 failure in every 10,000 OFHG changed lol There are techs that have replaced hundreds of these gaskets and they've never heard of this issue. It's an odd one for sure... |

That said I'm still reeling in utter shock on this topic. Can't believe I did so much research on E90 OFHG work and missed this crucial issue. This probably explains why there is ZERO online DIY tutorials for the 2011 E9x N55 but hundreds of online DIYs and videos for the 2010 N54 and 2012 F30 N55

There are no DIY's because it is an easy job and N54 tutorials exist. There is no difference between the two cars in regard to the ofhg job except the intake manifold on the N55 makes the job slightly easier I believe. You don't need to remove it you can just loosen it. |

There is no kidding the X5 N55 forums tho.... I feel bad for those people. E90 folks tend to be the drivers who understand our cars and tend to DIY stuff and tend to be younger and/or eager to learn and above all sacrifice because we love our cars. Imagine a soccer mom in her X5 trying to figure out why her engine imploded after a recent mechanic visit to replace a leaking rubber oil seal.

That said with 90% of the work involved regards what you remove to get to the bolts I felt the N54 E9x and N55 F30 DIY were useless to me. I've done the OFHG on my E46 (2001 330i) so I know what to expect once I get the housing open. It is just the getting in there scared me. Now I've managed to find something that scares me more....engine seizure. Another reason I've been putting off DIY my gasket is I want to produce a DIY video on the 2011 - 2013 N55 E90/E92/E93 cars specifically. So naturally I wanted to learn as much as I can which after months of planning, procrastinating, buying my E10 tools, and reading every scrap of intel I could find I'm surprised that I'm only learning about these N55/OFHG engine seizures now. In fact I found this thread ONLY because I was searching for a parts number for a ashtray plug. When I saw OFHG I decided to read what it was about. My world is forever changed now.

It's not easy to come across this intel because it's literally 20 people out of millions of cars (that we know of). Would love to see someone with some authority pressure an investigation into engine failures. People can submit a claim to NHTSA, state attorney general, or consumer protection office like the BBB. Start sending BMW certified letters showing the damage and requesting reimbursement. Not likely these failures amount to any significant defect though that they will ever address... |

New to forum and DIYs looking for tool advice
Looking to start a job on replacing some gaskets like valve and oil filter housing and doing a intake clean while I am at it.
What is a good full set I need to do a proper job and have the right tools for the job. E90 N55 |

Did OFHG without torque wrench. Though I would not recommend that.
delmarco As for the metal railing that you mentionned, it really doesn't ring a bell and I am an xDrive owner. All I had to do was remove air filter and the box with it as well as the scoops right over the grills. I then removed coolant line before even touching OFHG so it minimizes spills and contamination chances. Then I loosened the intake manifold bolt and started working on the OFGH 3 torx bolts. Finally, bbnks2 I've read a bit on the N55 oil pan and system. I am pretty sure there is a design flaw where the pump can't feed in a consistant way when the system is exposed to ambiant pressure and air might introduce itself (OFHG replacement). But then there are also a lot of inconsistencies that would not really support this. I still have to check the N54 oil system. I just think that a simple baffle in the pan could of helped a lot but then again I have no clue if this even makes sense.
