Anyone have to replace the oil filter housing gasket?
I have 124k on my F30 and know there is an oil leak but minimal one. I had to get a new battery today so the dealer said one of my leaks is the oil filter housing gasket. Anyone else have this issue? If so, how much were you quoted and is this a DIY or too labor intensive? I know a valve gasket is leaking but they said this one will need a repair due to under pressure and will get worse. Other than those issues they couldn't find anything wrong with my car-thankfully.

This is an easy fix at home. If that's not your thing, do not go to dealer. Find a good independent BMW shop to have this done. The dealer is way to pricy for regular repair work.

Common with every modern BMW to my knowledge. My n20 is 5.5 years old and it's dry which I consider fairly reliable, I'm guessing engines with more horsepower and higher thermal stress experience failure earlier.

What is needed to prime the engine after? I watched the videos on how to change the gasket and it seems relatively simple. Dealer wants $1,000 and appears to be 2 simple gaskets for $60 and a couple hours of time.

Had my N55 OFHG replaced by the dealer under warranty. I only paid a deductible, but the cost I would've paid w/o warranty was $679.96.

I'd read up ion this priming business,. I have been driving Bimmers with inline 6 motors for 15+ years- I change my own oil and filter, DIY a lot of my service/repairs - have never 'primed' any motor after OFHG gasket replacement or a straight oil/filter change. I've read a few of the N55 posts on the topic, I'm highly doubtful on the need to do priming after gasket change; I don't feel the proof of need to prime has been validated-

I've replaced a few. It's one of those things that's not hard once you do it the first time lol. The alternator removal on the M54 had a "technique" to get it out, other than that the procedure was cake.
I don't know anyone that does the engine oil priming procedure but basically it's removing the injector connectors then cranking the engine over a few times to get oil into the system. The only times I've heard it's done is engine swaps. |

Let's see, another hour of labor at $130 an hour...
You do have to add both oil and coolant to replace what was lost in the process, but that's all that my Bentley manual makes mention of. |

It's not like your draining all oil out of the engine and flushing it to a bone dry condition through-out. There is still oil clinging to all the surfaces during the gasket change just as if you were doing an oil/filter change. Good money-maker for the dealer. I don't know of any of the BMW specific Indies that I have used since 2003 that recommend or try to push that procedure. Since yours was a warranty repair, its a money + for the service department without having to talk you into it.

Easy job. Did it myself as well. I didn't prime anything and motor is fine. Only thing that kinda sucks is that you have to loosen the intake manifold to get to one of the bolts.

I think I will hold off about a month to change the gasket and then do an oil change at the same time. It seems logical to me to do an oil change at the same time. Should be a short 2 hour fix. I will watch the priming video.

I replaced both gaskets yesterday so that repaired my oil filter housing gasket. I still have a valve cover leak but after watching that video not sure I am up for that challenge. This was fairly easy but the valve cover seems a bit more in depth. Anyone done the valve cover gasket?

I did, and referenced the above video. Hardest part was actually prying the VC off itself. I use some plastic trim pic tools and slowly worked the front corner (near the OFG) and it must've taken me a full hour of working around the cover just to break it free from the head. Lastly... I don't have the part number, but go ahead and pre purchase the vent hose located on the valve cover's front right side. It's brittle as heck after my 60K and you'll most certainly snap it off.

How long did it take to replace the valve cover gasket? It seemed that my biggest leak was the oil filter housing gasket which at least is now fixed. Debating how soon I want to tackle this project.

It all depends on how quickly you can dismantle all the stuff in the way. It's not hard but lengthy. I think the shop quotes 4 hours. I did mine a couple weeks ago but rolled the gasket a couple times and took a lot of breaks. I spent a total of 5 hours. She is good to go now.
