I can see the oil dripping below the engine about one drop per second which is too bad. I tought it's the front shaft seal but when I looked more closely it looks like the oil is flowing and comming from somewhere around the base of the oil filter can. http://www.realoem.com/bmw/showparts...68&hg=11&fg=30 I suspect the o-ring 5 or the gasket 6. Does anyone have idea what is 4 called bush for? I hope you can help me with your opinion or if anyone experienced this before. Is there any way to find where exaclty he oil is coming from?

Id suspect that #6 is the culprit before #5 but since theyre so cheap, id replace both while in there. Have you done an oil change lately? If so, have you made sure to tighten the oil filter cap securely and its on straight? How about the oil filter cap o-ring, is it sitting straight for a complete seal? __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone 1998 Schwartz II sport 318ti - M50TUB25/5 | | | 12-24-2007, 06:56 PM | #3 | Senior Member Join Date: Nov 2004 Location: Minneapolis Posts: 1,587 | I've replace #4, #5, and #6 before. From my inspection the gasket was the cause of my oil leak. It stopped after I replaced it. Here's a pic of that "bush" (#4). It actually came with the two O-rings (#5). I ordered the o-rings seperately, and now have two new ones sitting around. Anyone want them? Here's the gasket If you do this project, I'd recommend hosing down the area with brake cleaner and scrubbing it clean with a toothbrush before you take the filter housing off. It's so dirty around there, it's easy to get crap into your oil system. | | | 12-24-2007, 10:23 PM | #4 | Senior Member Join Date: Jul 2006 Location: Weymouth, MA Posts: 215 | Thank you for the information, I guess the problem is the gasket. CirrusSR22, how does your oil leak looked like? I just want to compare with mine. My look like this: there is a little oil "pool" on the engine block right behind (next) to the base of the oil filter can. From there, the oil is going to front cover and using one furrow, flowes down to the bottom of the engine where is all messed up. The drops fall to the ground from the power steering . The leak is bad when the engine is cool and almost gone when it's warm. __________________ '96 BMW 318ti Hellrod 5SPD - SOLD '04 BMW X3 2.5L Alpine White PRM PKG Automatic/Steptronic PRM PKG - SOLD '01 BMW M3 6SPD Imola Red Luxury PKG '11 BMW X5 xdrive35d - 3.0L Twin-Turbo Diesel - The Ultimate Oil Burner | | | 12-25-2007, 06:20 AM | #5 | Senior Member Join Date: Nov 2004 Location: Minneapolis Posts: 1,587 | I did notice oil in the spot you mentioned; I know exactly where you are describing. I originally thought my oil pan gasket was leaking (the whole perimeter was showing oil), but after more investigation the leak was from higher up. This was the most logical spot. My power steering rack area was pretty bad. Oil mixed with dirt, but it wasn't wet with oil. I kind of forget where the drips were from as it was a few years ago. This leak also disappered in the summer, and reappered in the winter. I'd notice oil spots on the ground. | | | 12-25-2007, 05:59 PM | #6 | Senior Member Join Date: Jul 2006 Location: Weymouth, MA Posts: 215 | Quote: Originally Posted by CirrusSR22 I did notice oil in the spot you mentioned; I know exactly where you are describing.

How hard is this project? Do you remember how you did it?

It's not too hard. By memory, you have to remove the: •Entire airbox/intake •Alternator. There are two long bolts holding it onto it's mount. You need to lever the alternator out after the bolts are removed. It took more force than I expected. There are also a few electrical connections, but they are not too hard. • I possibly removed the mount that the alternator is attached to. • I think I also has to unbolt a pulley, or maybe loosen the power steering reservoir to access an alternator bolt. Something in there. Oh, I also drained the oil from the engine first. Maybe not necessary, but I needed an oil change. Overall, it's not hard, but you do need to dig a little deep into the engine to get access. | | | 12-26-2007, 10:03 PM | #8 | Senior Member Join Date: Jul 2006 Location: Weymouth, MA Posts: 215 | Ok, I opened the hood this morning (before to start the engine) and I looked around the top of the oil fiter can base and it was dirty but dry. I started the engine and looked again at the same spot and man I saw a fresh oil stream comming out of the top right of the filter can base. The oil leaked to the bottom of the engine and made about 2 inches wide spot on the ground. Two minutes later the leak was almost gone when the engine rised it's temperature. This is the proof that it's 100% the same problem. I am ordering the parts now. Thank you for your help CirrusSR22, I hope I'll have this fixed soon. Additionaly I'll replace the valve cover gasket and the spark plugs hole gaskets using your nice DIY. The reason is the same like yours, there is some oil on the left side of the valve cover (sometimes an oil drop drips over the exaust and you can feel a "nice" burned oil smell) and oil in the second spark plug hole. __________________ '96 BMW 318ti Hellrod 5SPD - SOLD '04 BMW X3 2.5L Alpine White PRM PKG Automatic/Steptronic PRM PKG - SOLD '01 BMW M3 6SPD Imola Red Luxury PKG '11 BMW X5 xdrive35d - 3.0L Twin-Turbo Diesel - The Ultimate Oil Burner | | | 12-26-2007, 11:38 PM | #9 | Senior Member Join Date: Mar 2005 Location: Detroit, MI Posts: 585 | I just replaced bush and the gasket on saturday (Dec 22). Cirrussr22 is right about what you need to remove: All airbox components, radiator fan, alternator, and just loosen the power steering pump. So far there hasn't been a leak and when I got down there, there was a considerable oil puddle on the engine. You don't need to order number 5 on the diagram, it comes on the bushing. While your at it, if you haven't already, go ahead and replace numbers 4, 9 and 13 http://www.realoem.com/bmw/showparts...67&hg=11&fg=35 and replace number 1 http://www.realoem.com/bmw/showparts...58&hg=11&fg=10 you can easily get to that piece without having to remove the intake manifold (even though you can do it without removing it ) | | | 12-27-2007, 08:03 PM | #10 | Senior Member Join Date: Apr 2006 Location: Oxford, Ohio Posts: 868 | I have the exact same problem, too, but the leak is not as severe. I just ordered the parts today, but without the o-rings. Cirrus, I'll take you up on your offer if mine comes without the o-rings from the dealer. Anyway, this seems like such a common problem, so I think I'll get out my digial camera and make a DIY while I'm at it. | | | 04-14-2008, 06:56 PM | #12 | Senior Member Join Date: Aug 2003 Location: cary, nc Posts: 2,259 | nice job dave, i have that same oil leak i think....this helps a LOT! __________________ 1995 318ti Active Pioneer Speakers [] Aluminum Billet door locks [] ACS Pedals/Deadrest [] ACS Shift Knob / E-Brake Handle [] Clear Corners/Tails/Sides [] Sylvania Exterior Lighting [] Custom CAI [] Dinan Engine Chip [] Dinan Transmission Chip [] H&R Race Springs [] Tokico Illumina Shocks [] BMW X-Brace [] Relocated Lighter Mod [] Custom iPod Mod http://www.cardomain.com/id/robcarync | | | 04-22-2008, 03:43 AM | #13 | Senior Member Join Date: Sep 2007 Location: SoCal Posts: 305 | Quote: Originally Posted by tol4o there is a little oil "pool" on the engine block right behind (next) to the base of the oil filter can.

The leak is bad when the engine is cool and almost gone when it's warm. | I have an oil leak I'm not sure where its coming from but its dripping from the cross brace. I sounds like it could be the oil filter housing but wouldn’t that drip from the power steering rack not back by the cross brace? Edit: it now looks like Niagara Falls under the car. __________________ | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
