Asked by May 03, 2009 at 02:10 PM about the 2005 BMW 3 Series 325i

Question type: Maintenance & Repair

I have notice a minor oil leal in the front of the engine behind and below the power steering reservoir.  It's motor oil not power steering fluid.  Is the oil pressure sending unit located in that vacinity?  If not do you have any ideas on the cause? Thanks in advance for your help.

The Oil Filter housing stand (assembly) is located there. There is a rubberized gasket that mounts the Oil Filter housing stand to the engine. Likely, that’s what's leaking. You have to take the serpentine belt off of the respective pulleys (you do not have to take off the A/C belt). Remove the plastic covers from the tensioner and idler pulley (pry out with a small screwdriver). My tensioner ('04 325i) had a Torq head bolt. I've seen them with regular bolt heads. Disconnect your battery. Remove the positive battery lead from the alternator, the alternator and idler pulley. You can just unbolt and move the power steering reservoir out of your way (you probably should cut the end of the reservoir's bottom hose off and put on a new clamp). You may have to remove the power steering pump (you can leave all hoses attached unless you plan to change them or cut the bottom one). Check this as you go, it seems like I got by without removing the power steering pump. The upper or lower end of the Vanos hose (banjo bolt) may also need to be unbolted (you'll need 2 crush washers to reattach one end) to help with space to work. The Oil filter stand has about 6 bolts (not all equal in size/length). Pay attention to, and label, which goes where. Unbolt the stand from the engine. Clean everything (brake cleaner spray is probably good provided you then clean any residue off—Dawn liquid is good for this). The gasket and crush washers can be purchased over the net or at a BMW dealer. They are not expensive. You just pry the old gasket out of the Oil Filter mounting stand, clean the track, and smooth in the new one. Be sure not to over-tighten the bolts. I think it is 10 Newton Meters. You can check the net for this. Then reassemble in reverse order. Good luck.

Thanks Tracker. I found out it was the head gasket and I was was also leaking coolant into ajoining two clyinders. The mechanic said that those two cylinders were "washed" and if they did a head gasket he could'nt guarantee it would not burn oil. He had some sort of opitical light he could put into the cylinder to view. The engine had 80k on it and he can get a replacement motor for $4500 and installation fees. The replacement motor has 40k and come out of a wrecked 2005 325i. Supposely it was a rear end total. You sound very knowledgeable, hows does that sound? Thanks for your help.

Sounds like you got hosed bud. Did you ever see your motor out of the car? Did you see the replacement motor? I'd check the vin if not.
