Hi I own a BMW 645Ci 2004, Automatic Coupe I have sprouted a leak from my expansion/header tank, from what looks like the lid/top. There appears to be a gasket/seal of some sort between the top and the main body of the expansion/header tank. The water is leaking from there. I have sat and watched lots of videos on how to replace the whole header/expansion tank, but non showing how to just remove the lid to replace the gasket/seal. I can't seem to see any clamps, clips or screws holding the lid on. So, Im assuming that the whole thing has rot be replaced - thought I would check here first though. Cheers Mike

I must admit I am finding myself topping up the oil every now and then. Someone told me that v8's burn a little oil, so didn't think too much of it. I'm thinking now, that oil is dripping onto a hot exhaust. But how to find it ... Bmw will charge £138 per hour to find it :(

Hi all I am in need of some advice for my BMW 645 Ci (2004) car .. I have noticed lately, that when I pull away after being at idle, in traffic or traffic lights for a long period, , I get a cloud of blue grey smoke from the rear of the car. This "smoke' does not appear while driving normally, at high speed or accelerating. Engine sounds and runs fine. I thought, it might be a slow oil leak and its dripping onto the exhaust. But, I am no expert. Just to add - It only happens when the car is running at its correct temperature ... Any advice from anyone is much appreciated Best Regards Mike
