Very helpful! I was able to follow these steps and successfully complete the oil filter housing gasket replacement. Do you happen to have any instructions on replacing the heat exchange gasket? This is also leaking.

I'm afraid I don't, as I don't even know where is the heat exchange gasket? Are you referring to the cylinder head cover gasket?

Thanks for the DIY. Planning to tackle this along with the VANOS. Is there an RTV Sealant used along with the gasket? Or is it simply,

1 remove old gasket (scrape)
2 clean area for new gasket
3 install new gasket

No RTV sealant is needed for OFHG.

Oil Filter Housing Gasket - Replacement (M54)
 
Excellent DIY. When I did mine on my previous e39, I found that in removing alternator, spraying a bit of wd40 at the contact points to the engine block makes it come out nice and easy with no jerking necessary.

One question , do you need to drain engine oil prior of this task?

Slim Grim asks a good question...


Does anybody who has performed the OFHG R&R on m54 engine know if it's necessary to drain the oil? If so, is a typical drain from the oil pan plug legit enough?

Never done this job but am tomorrow. I have no idea how much oil is lost from removing, cleaning, etc... If the amount is negligible then that's that. But I could also see a drain & fill being possible.

Hey boys, sorry for the late response, but I don't think you will loose any oil with this DIY as the all the oil sit in the pan at the bottom of the engine. I could be wrong, so to be on safe side, better drain the oil anyway. If you don't want to spend more and think the oil is good, use the old oil and topup with 1L if necessary.

You are pretty much spot on. Just pulled mine off of my 2005 530i. It's almost exactly the same as my two E39's, except that there are three bolts on the bottom of the housing that are connected to the power steering pump, in addition to the normal six bolts that you may be familiar with in an M52 or M52tu from an E39. Two up front and easy to reach, and one difficult one on the back rear. The pump literally mounts to the bottom of the housing. No oil lost other than the mess spilled all over the place when I pulled the housing out. Just open your oil filler cap so the oil will drain down from the filter housing. I'm doing an oil change anyway, so I drained the oil pan before I pulled the housing.

I was following it just fine until I removed the 6 bolts---then I was like, this is way too much coming off compared to your DIY. Maybe I missed it, but with mine, removing those 6 bolts (all diff length), the power steering pump/assembly also comes loose/off (attached to OFH)?

I'm searching now, but man, not a good day to hit a snag. Also replacing CCV and bunch other stuff which I'm familiar with, but first time doing OFH. sigh.

Jarhed1964. Are you saying I have to remove 3 more bolts to separate the OFH from the power steering pump? If so, i would think a support is needed to keep pump and all the hoses from bending/falling?

UPDATE: I figured it out. I found another DIY that did mention the two PS bolts. :-) Man, OFH and CCV are a bear. But it was easier doing CCV with OFH. However, I've done CCV without doing the OFH. Having done both, yah, it's easier, but I'd still do the CCV alone if I had to do again (assuming OFH was ok).

My repair shop told me I needed to replace the bolts when doing the gasket swap - apparently the aluminum bolts they use are single-use and can snap off when re-torqued. Anyone else hear this? Sourcing those bolts is a PITA so far.

Had no issue re-using mine. Over a week and no leaking.

+1
I think replacing the bolts may only apply to the earlier N52 engines. IIRC all bolts that are one time use are marked blue. On the M54 its ok to re-use the same bolts. I re-used on my previous E39 with no issues. My 04 just started leaking so I will be making the repair soon.
