If sentences are this hard for you, then yes, repairing a bmw will be quite difficult.

Very nice post. It helped me out a lot. I did mine this afternoon. It took me about an hr and a half for the work, about 2 hrs for cleaning. I got it pretty clean, but not as good as you. I also went ahead and change the VANOS oil line gaskets while I was in there. Torque for those is 32 Nm (24 ft-lb). Torque 22 Nm for the M8 oil filter housing bolts. Just in case others need it. Thanks for the help, man!

BTW, I know this is an old post, but just thought I'd give props.

CHECK THE OIL FILTER O RING FIRST!!
Had this problem recently on '00 328 with 170k - replaced the OFH gasket twice! looking thru some of the posts one big thing to watch is the oil filter O ring- even in the pic above it is not installed right- I had done 8 or 10 oil changes and did not have any leaks till the most recent one- oil was pooling under the right hand side- just like in the OFH diy pics posted. Pulled it off again put a new one on and carefully torqued to spec, put back together- oil change and filter- STILL LEAKING POOLS OF OIL!! got feed up and took to local indy shop - if your in Sacramento CA area the guys a Stewarts Auto are the best - tech took one look at my filter O ring and said 'it's on wrong' the O ring should disappear inside the filter reservoir when it seats. IF YOU CAN SEE YOUR OIL FILTER O RING IT'S ON WRONG AND WILL LEAK DOWN THE BLOCK AND LOOK LIKE A FAILED OFH GASKET. Took cap off and looked real close at the 'groove' about 1/4 inch below cap lid and right above threads- there was a old O ring embedded in the groove!! pealed it out with a small screw driver- installed a new O ring, replaced cap- O ring vanished into reservoir!! NO MORE LEAKS!!
CHECK YOUR FILTER O RING BEFORE TACKLING THE OFH GASKET!!!

Thanks for sharing your findings. When you buy the oil filter it comes with a new O ring. So when you change your engine oil, this is part of the maintanence to change that O ring. Sounds like in your vehicle, previous owner neglected to change it.

Yep, I picked it up 2nd hand and have not had a problem with previous oil changes.. wish I would have seen someone point out the 'vanishing O ring' before I did the OFH 2x

1. drive car on ramps or put on jack stands.

2. remove bottom engine splash shield

3. remove air filter box and remove the 2 nuts holding up the power steering reservoir. Put it to the side.

4. Remove fan and fan shroud

5. remove upper radiator hose (optional step, it just help clear up some room)

6. remove the alternator belt.

7. disconnect the negative of the battery first before messing with the alternator. (added by SSM1991)

remove alternator at these locations. I think the 2 bolts are 13mm. pull the electrical connector and unscrew the red battery terminal (13mm). Also remove the lower air 3 inch duct.



8. with the alternator out, its time to remove the 6 bolts (13mm) that holding the oil filter housing to the engine. Important: Remember the locations of each bolt because they're different lengths. It will help alot when it's time to re-install the housing. Also remove the oil line at the top near the radiator hose and remove the electrical connector to the oil housing.





9. Pull the housing away from the engine. as you can see there are small collections of oil nearby. I didn't completely removed the housing, I just pull it off enough to remove the gasket.



10. picture of gasket that's harden and brittle. it's cracking in a few spots.



11. replace with new gasket and reverse all steps to finish.

12. top off coolant and some oil. Oil doesn't really leak out at all when you pull the housing off.



I dont see any mention of the Power stearing PUMP removal.. i saw a youtube how to and he removed 3 bolts, is it necessary to do remove the pump??

some cars its not necessary to remove. I had to do it on an '04 but not on a '99. Its extra 3 min job if you do. No big deal.

Man this was so much easier than I thought only took an hour or two. Even did it without taking out the fan or shroud. Longest part was letting it cool down. But I must say getting the alternator back in is a pain.

I just finished installing my new DISA and took a look at the "honeycomb" area and definitely there's alot of oil there so I'll probably be changing the OFHG next weekend (already picked up the gasket at BMW)

What was the hard part about getting the alternator back in?

Just getting it lined up. It's kinda of wedged in and it's a very tight fit took a little persuasion to get it lined back up. Not to terrible with two sets of hands.

I just replaced my alt.. didnt have too much trouble w/ it.. i found that the bottom bolt was tough to pull out when removing.. just took a pliers to it and wiggled free... gotta take it out again tho.. im just wondering if i need to remove the PS pump.. if i do then i need to get some rhino ramps... ill just get the ramps for this and future repairs... im excited to get my car fixed up..

OFH gasket, then window washer pump, then pillars.. those pillars are bugging me.

My alt wasn't bad at all...the bottom bolt that has the "bushing" was about 1/2" from even being seated...it was previously replaced, at what time I don't know. I will say all my bolts were torqued back together though. I think you can drive that bushing back out a bit so that when you do put it back in, it just slides in place, then when you tighten it back down it seats again. Ofhg isn't that bad to do, just take your time and make sure you tighten everything up.....so you don't find what could have been catastrophic to mine.

Did this today. I've already done a VANOS, CCV, and lots of other things - but this, by far has to be the most bang-for-the-buck repair ever. It really is fairly straightforward, and I spent about $5 in parts (carquest had the gasket and the two crush washers in a couple of hours for me). I feel stupid that I've been putting in a quart of oil so often ($7) when the cost of this repair was less than a quart.

My observations:
(1) If I wouldn't have cleaned anything, it would have been really quick (<1hr). I spent about 3 1/2 hours because I had a freaking mess in there.
(2) I did not remove the power steering pump. If I would have, I probably could have taken the whole OFH out and cleaned it separately. I pushed it to the side and made do, and still cleaned up everything rather well.
(3) You might as well check your serpentine belt before this repair, I should have, I would have replaced it.
(4) The pipe that connects the alternator to the fan housing pops right off. I had to pop it off after simple-greening, hosing, and scrubbing my engine as I got water in it. You might as well pop it off and shake out any debris in it.

Today I replaced my oil filter housing gasket, coolant tank, belts, pulleys, water pump and a bunch of other stuff.

I'd like to add a tip that helped me keep order of the six oil filter housing bolts. I took an empty box and using a knife cut and twisted six holes in it that roughly resembled the bolt order on the oil filter housing. storing the bolts in the proper order helped me later when reinstalling them.
