Can't tell you what the goo is, but my car has it as well (same color, too). I'm not aware of any problems with my car that might have caused it, so I'd be tempted to agree that it's a normal build up of something. It is a build up, however: If you look closely you should be able to see the silver underneath.

From what I can tell, there are a certain number of things that tend to fail at around the same time on e28 M5's (and e28's in general). If you buy a car that's had all of that done, you should be in good shape. Otherwise, expect a few bumpy months.

Best thing to do would be to check the car's service records against the noted problem areas at's buyer's guide and maintenance information. I personally had to do the front control arms (expected) and the injectors (unexpected), along with continuing miscellaneous electrical stuff.

It's worth it, though. The car's a blast to drive. Good luck!

Can anyone comment about the seeming staining of the valve cover here. Is it normal residual buildup from acceptable emissions?Is it a signal of a leak somewhere? Were any given this coleration from the factory? Were others which appear bright just washed regularly? In all my searching for one to buy. Since i missed on a member's a few months ago,this is the one most appealing by virtue of the mileage, price and location . A southern car gives me a lot of comfort being from the northeast.One more question, I can't say i have any disposable income and i would be mortgeging my no mortgage condo to buy ,is there any manifest rule with this car where certain parts regularly fail and if so what should i be prepared to replace in the near future. Thanks ,an addict.
