Peeps,
Not an Audi issue I'm afraid.
My old uncle's BMW E46, with a 2.5 straight six engine, has developed a small engine oil leak somewhere to its rear (half a litre every 3 months or so). I can't get a good view to the back of the bloody thing or from under either.
I've replaced the cam cover gasket and oil filter housing gasket, so doubt can be them again. Appears to be coming from where the engine meets the gearbox when observed from below? I suspect it will be an expensive fix. Any ideas?
I was thinking of using one of those Stop Leak products. Anyone have experience of these or can recommend/warn me off such a thing?
