I have got a drip, drip, drip of an oil leak. Its yet to hit the floor but is collecting in the plastic belly pan. One side of the engine is wet with oil but I cant really see where its coming from. The front RHS (US passenger side) is the affected.
I took off the belly pans and looked up under the car, the epicentre of the leak if you like seems to be shown in the photo and the hose 'junction'. Sadly I have no idea what this part is, or if indeed it is oil related. It is just by the aux drive belts. Can anyone identify the part shown? It seems to be where the leak is coming from. Real OEM doesnt help me.
I think that steel valve type thing is the check valve for the secondary air system. Can you take more pictures from a little farther away?
My suggestion for you would be to clean all the old oil off and see if you can see a trail after driving it for an hour. Right now it looks like it could be the Vanos O-Ring on the adjustment unit or maybe yout timing cover is leaking? Have you checked your Oil lines from the filter housing/Powersteering lines for leaks?

Probably going to turn out your valve cover gasket on that side. I assume the top of your motor is dry? Like your oil cap and all the grommets that hold the valve covers down? I agree with the above. Clean that off with some good engine degreaser and a brush and let it dry. Try idling/revving for a few minutes and look for the leak before driving. Engine bay wind can really make the oil swirl around. If you need to drive go real slow to keep the wind down.

If you want your oil pan repaired (see http://www.m5board.com/vbulletin/e39...rain-plug.html) instead of buying a new one or attempting the repair yourself PM me and we'll work something out. Thinking $60 profit is worth it. You pay all shipping of course. At the moment I have four remaining Timesert inserts looking for homes. If the demand is there I'll keep doing them. If not the tool goes on eBay minus one insert.

Thanks for the advice. I have tried to clean it up but to be honest it is all so filthy I cant really get it clean enough to see new trails!
Valve cover gaskets are a good shout. Can you detect them weeping with the engine running? Im guessing you have to slide your hand right down the side of the block?
You can also easiely take off the cover of the solenoides,then you see if the O-rings are leaking and cause that problem.Have just done that on saturday on another board member's car to see where it was leaking.In our case it was the O-rings...

Hi,
Yes I have been reading the instructions for removing the solenoid covers. From your first hand experience is it quite easy to simply remove + inspect?
Presumably when the cover is off you can see a deterioation or a break in the O ring.
It is easy to do,let her cool down and open the coolant cap to remove the pressure from the water hose,makes live easier!
You have to pull the solenoides to see anything more on the O-rings,like the DIY thread says...
But to see if they are causing your oilleak,it is enough to pull the cover!And don't forget to tighten the blots again with 19NM torque....
Be careful when you remove the covers that you don't break their gasket if you don't have a new one...

OK thanks. So its worth just buying the gaskets + 16 O rings in preperation by the sounds of things. Bearing in mind they are not expensive and will need doing at some point in the future anyway.
I will start there. Appreciated.
Is worth it!Just try the cover first and see if it is leaking there.Changing the O-rings and removing the gauze filters and cleaning them is not such a hard job,have done that last week on my beast finally.
We will do quite soon with some of the finnish boardmembers a "Group O-Ring Change Event" on their cars...
