oil disptick o-ring housing leaks?

[omodos]

Hello maybe me being over anxious but had starter replaced mondAY ....and today had a look under car and noticed what you see in pics looks like oil...anyone else had oil from disptick tube lower end appear like this as a leak?

Guy changing starter in process removed the bolt 18(then replaced all) that actually holds the dipstick housing tube , so wondering if this and wobbling of dipstick tube damaged the o-ring on its lower end...car was leak free so far since purchase!very very frustrating, ding dong also left off some screw that hold the plastic underbody in place...cannot for the life of me find it on realoem so may have to stick in some customem grommet or screw.

I removed the upper dipstick mounting as part of removing the intake manifold when I changed my glow plugs and controller. No leaks after several weeks. I guess it would be possible to split/crack the dip stick tube or un-seat if it was in the way of access to the starter motor. It certainly does look like you have a leak down there somewhere.

Regarding the trim retainer, they are a plastic push-pin deal (BMW call this an expanding rivet) and they often break when you remove them. I have a box of new ones I use when I pull these panels off...

BMW part number is 51111908077 but I use aftermarket copies.



The aftermarket items are often called "scrivets". Champion is one brand we get in this part of the world...

hmmmm will look into this as what I have on the other side on X5 is the bmw oem part that doesn't look the same as the expanding rivet you mention, ok its a screw after all i will plug in something else at the end of the day to stop the plastic flapping about PLUS on close analysis of the the identical side of the car under drivers area I see the same stains as on the other side where I thought there was an oil leak...could well have water that had not dried out....too much of a coincidence it being oil from the dipstick holder o-ring ending up on that side too...so apology is in order to all
