Does the amount of exhaust smoke during revs look a bit abnormal in my video or would you say that my culprit looks like it could be a leaky head gasket.
2008 528i 163,000km automatic, and current maintenance that I'm doing in the next week or so include oil filter housing gasket, and serpentine belt but those are effortless and I just felt the need to mention incase those upstanding repairs may relate to anything else.
I see nothing of concern. What was the outside temperature for the video?
Blown head gaskets 101: oil in coolant, coolant in oil, oil or coolant leaking beween head and block, bubbles/high pressure in cooling system, oil in cooling system, low compression in adjacent cylinders. Do you have any of these symptoms?
Not that i know of at the moment, i am however gonna wipe down the engine block just incase if there is anything it should make it easier to track at the very least,and the temperature was roughly 4-5 degress celcious.
Probably condensation due to warm moist exhaust (yeah, moist), combined with cool ambient air. If you can see your breath when outside, expect your car to puff too.

I've done an N54 head gasket - turbos have to come off obviously. If you can get the engine out from underneath the car with the transmission intact (using a 2 post lift) that's probably the easiest way to get the job done. Lots of time involved. Would be the same advantage if you replace the engine - you can leave the front end intact with the radiator, oil cooler and all the heat exchangers installed. Good luck.
First off drain your oil and check to see if there is any anti freeze in it. You'll definitely be able to tell. Then remove your oil fill cap to see if theres any cream coffee like residue on your oil fill cap or inside the valves, use a flashlight. If that looks ok then its most likely your oil cooler gasket. Thats an easy fix 3 bolts, $17 gasket and while your at it replace your oil housing gasket too. After that flush your radiator with warm water and a little dawn. Do 3 flushes. you will need to pull the hose from the bottom of the radiator to drain the fluid and get your thermostat to open to circulate the water to flush out the oil. Leave your reservoir cap off while flushing. Turn on your key without starting your car and push down the gas pedal for 10 seconds, that will engage the circuit to open the thermostat. Its very rare that N52 N54 head gaskets go bad. This just happened to me and it was a oil cooler gasket I overpaid on and was taken advantage of by some low life mechanics or shop owners!!!
