[Black 2002 325i]

My father in law has an 04 525 and he called me and said he was putting a smoke screen behind him going down the road.

I had him rev the engine and it looks like water/oil coming out of the exaust.

Check out picture... anyone have a guess at what 'may' be the problem. the car has well over 100,000 miles on it.

anyone?

check the oil and coolant for more clues. since this looks pretty bad have him drain both so you can get a good look at it.

really really bad headgasket leak?

what colour is the smoke?
if it's blue, you're burning motor oil.
if it's white with a weird stench that doesn't smell like unburnt petrol, then it's pretty sure a headgasket leak.

Same thing happened to me and it was a Cracked Head :facepalm: Good Luck , I hope it is something else .

take the radiator cap off cold, start the engine, if coolant comes flying out i will be from the cylinder compression escaping through the head gasket.
