HELPPP!!!!!!white smoke coming from engine bay! - BMW 3-Series (E90 E92) Forum

RPH90 · 05-01-2012, 07:32 PM

Hi all,

I have a 2006 320i e90 which has just started to pour smoke from engine bay after being driven for 5 minutes or...I have always had a minor obvious oil leak from the rocker/valve cover gasket which I noticed through the burnt candle smell through the AC.

I have taken it to a mechanic and he believes that they need to replace the brake vacuum pump, rocker cover gasket, oil filter housing gasket and fronmt engine solenmoid seals?

I want to know if this is indeed the case? The smoke is white and does have a slightly different smell to that of the oil (but maybe its just me). I am startignt o notice that the coolant levels are also going down.

Could this be a coolant leak somewhere which is causing the large amount of white smoke (embarrassing to drive)?

Please note that their is NO smoke coming from the exhaust...

White is usually coolant I think

yehhh white for coolant - thats what i thought also - i think it is obvious that somethign is leaking and dripping onto the exhaust manifold. the smoke isnt coming from near the radiator thought - like at the back of the engine itself (or even more towards the passanger side in AUS).

Perhaps a crack in the coolant expansion tank or a cracked hose. Do a pressure test to verify.

water in engine?

How can water get into the engine?

The smoke seems to be coming from under the rocker cover! But the smoke is white rather than black?
