I just finished mine and was not that bad. Just make sure you have enough time to do it right.
To remove the gasket I used a surgical type pick to get the gasket out. Just dig into the gasket at an angle a little bit and pull upwards. Do it in few areas and it pop right out. Does not scratch the groove at all where the gasket sits.
Also to remove the banjo bolt for the oil line, use a wrench that pivots. I could not get a socket wrench in there. No room. Also dont forget to replace the two crush washers.

I just replaced the OFHG. When I removed the housing some oil dripped out, I followed the DIY exactly. I still have drips. I cleaned everything up pretty good. SO, I am not sure if I am leaking from a new place or if the oil that spilled is still falling off engine parts. I cleaned it up again, I will wait 1 week and see if there are new puddles. Anything to check out. I also replace my VCG about 8 months ago.

I put some RTV silicone on the outer edge of the housing for some extra insurance. Damned if I will ever be doing it again.

I followed this DIY to do mine. The hardest part was putting the alternator back on. Tip: use a narrow screwdriver and insert it through the top thread hole (alternator through mount location on engine) so you can line up the bottom bolt. I really have to get a 3/8 in. torque wrench because I cant quite get to 25 m torque on the oil filter cap. I either leave it too lose, or tend to pinch the oil gasket.

Just did my friends this past weekend, not hard but the cleaning job took some time, alternator was very easy, no problems there. Need to jockey the entire housing a few time to get it lined up and over the dowels but that was all. Will probably do mine this coming weekend or maybe during the week if I get the time. We also replaced the vanos oil line which was leaking as well on the metal ends. Mine is doing the same. It took us about 4 to 5 hours complete off and back on. Next one I can see being quicker.

Were the six bolts torqued down to spec? Gasket possibly moved during installation.
Try using a flexible magnetic pickup tool that has a LED light on the magnet portion. The light is bright and you can bend it and snake into tight areas to check leaks. Works well. A small flex mirror may help also.
You can pick one up at the auto parts store.

Probably, it is time to add dye in the oil that will show the source of leak in ultra-violet light.

everything is torqued to spec. Gasket was placed inside housing and was snug when it was being bolted. I see a bit of oil on the waffle design area on the engine. The oil seems to oil on the drivers side middle of the splash guard.

I just did this on a 323i a little while ago. It was not as hard as I thought it would be. Not sure why everyone has issues with the alternator, seemed easy to me.

2001 330 i

Guys did all that ws listed - gasket and all. Thanks for the great DIY - I have a new problem - Once I put everything back - now oil is pressurizing and leaking in streams from the oil filter cap - in streams like spilling lava over (top is scrwed on and closed of course) And when I turn the engine off it is making a slurping/sucking noise. Everything seems nice and snug.. I did replace the oil switch as well .It is not throwing any codes inside or oil light on either. Did I miss something - is that little fan type thing inside the oild filter housing stuck or something?? I am wondering if I scrwed n teh filter back or if I left some gap... dont even know what to look for. and Dont want to take the whole thing apart. I am hoping its just the oil filter gasket

My Ride: '01 330i
I replaced the housing gasket on my newly acquired 2001 330i that had 117k miles on it.

I told the previous owner that it had an oil leak and he said that it was actually a PS leak that was already fixed. Either it also had a PS leak or his mechanic doesn't know the difference between engine oil and power steering fluid because it was definitely my leak...

I was able to do it all without removing the fan (it is an automatic car so the mechanical fan is a pain to remove). If you remove the fan it is probably a good idea to change the thermostat and possibly the water pump while it is off. And of course check your belt and replace it if needed.

TIP:

Remember to buy both the new housing gasket and new Vanos line crush washers. I forgot the crush washers so in a pinch I reused my old ones (but I plan on replacing them in a week or two when I do the Vanos seal repair).

In a pinch if you forgot to get new crush washers like I did AND you have copper crush washers you can heat them with a propane torch until they start to change color and then pour water on them to quickly cool/quench them. This will re-anneal them so that they will be soft enough to reuse.

I still recommend getting new washers but re-annealing copper washers can work if you forget.

Make sure all the rubber gasket are in place on the oil filter housing cap. (2 small & 1 Large I think?)
Also make sure its not cross threaded.
