OFHG XI Specific

Any tips of advice for this project? I did a search and most of this stuff is RWD specific.

Should we pull the entire housing? What is the best way to address the PS pump? Some people say pull it up and unbolt?

Any advice is welcomed!

Joe

I did my 330xi last fall. It's the same procedure. You can just unbolt the ps pump and move it out of the way. I did not remove the oil filter housing completely , just pulled it away from the block enough to clean it up and get the new gasket in. Keep track of the bolts. They are all different lengths and when re-assembling torque to spec in stages from alternating sides of the housing. You want to spread the torque as evenly as possible. It's a good time to replace the vanos oil line & crush washers while you're in there, adds 10 minutes of work. Use some brake cleaner to get all oil residue off the engine and everything it dripped on. Then you can easily spot any future leaks.

I did mine last week. There are many good diy's. The xi is the same procedure. The only difference I encountered from the diy I followed was that the bottom bolt holding on the ps pump was accessed from above rather than under the car.
Yes you do want to remove the housing. And do keep track of the bolts as earlier mentioned.

Leave the pump attached to the housing. You will have enough room to change the gasket without unbolting the pump or removing the whole housing from the engine bay.

You don't need to remove the pump. I had plenty of room without removing it. Make sure to give everything a good cleaning while you're in there!

Yup... I just did this job on mine this past Saturday. I had more room as I was also doing a cooling system refresh and had the fan, radiator, etc. out too.

Take your fan off, remove your belts, take your airbox out, remove the two bolts for the PS reservoir and let it fall over to the fender well... Remove your alternator and you you'll have the 6 bolts holding on the housing and two bolts holding the PS pump and the one coming up from the bottom. You might have more room as well if you remove your top radiator hose too...

Allow yourself 4-5 hours minimum if you have never done this. I read somewhere that BMW techs get paid 8 hours for the job. (Though a post around here shows around 3) After doing it once now I'd almost bet I could do it in 2-3 hours.

Should be fine without removing, but it'll be easier to get the bottom bolt from that position if you do want to remove it.

The seal did not appear leaking when i removed it but with 195k on the car I replaced it anyways. The CCV system on the car was 100% orginal and never been remove, I can tell from the way the clamp was on the intake boot was facing down. I replaced the entire CCV system. Both upper and lower intale bellows were cracked, I had lower on-hand but ordered the upper.

Part # 11617503622 is cracked but I'm not sure if I can use normal vacumm hose or should I pay $18 for the BMW Piece. Both

Last but not least, does anyone know what the Vacumm line that came with the CCV kit is for? Clearly the extra port on the CCV is blocked with a plug to prevent me using it?

My Ride: 2003 Jet Black 330xi
Just did my OFHG on Saturday along with an oil change on my 2003 330xi 5 speed. I removed the PS pump just to be able to completely remove the housing. Was all fairly simple just a bit time consuming taking all the parts off. Also had to run to the parts store and get a new alternator belt because upon inspection, mine was ridden with cracks. Was suffering from an oil leak and although I haven't checked since then (but I plan on checking my oil level today) I'm not getting the check engine oil light anymore after I shut the car down. Hopefully this solved my issue.
