Bought it almost 3 months ago and seems to be finding issues one after the other.
First it was the air duck that got smashed on the front passenger side (replaced it). Second, the windshield pump did not work and the spray nozzle (replaced it).

Did a maintenance replacing the water pump, belts, pulley and tensioner. Replaced expansion tank (nozzle broke). Replaced the cowl, replaced the rubber hose (snake) and the nozzle from the radiator to the snake broke also.

Smoke coming out on the engine on several occasions. Took valve cover out and there was a crack on the # spark plug area. Bought a new one installed and got it running. Smoke coming out again during test run. Seems that everytime if bleed the system that is when it happens (turning the heater on high). Can't believe what is happening.

Anyway, I drove the car to work today (bought a fire extinguisher and just being ready for the worse). Got to work and nothing happened (after showing it to my Buddy who has done by water pump replacement).

Any idea what is going on? I am still not very comfortable driving it long distance.
My Buddy said it is OK. I need more reassurance. Any advice?


Thanks

Maybe a small amount of oil from the previously leaky valve cover gasket dripped on the exhaust or somewhere hot enough to cause it to smoke? If you run the heater or AC the smoke/smell will come through the air intake ducts into the cabin every time you drive the car.

+1 regarding valve cover as the prime suspect. When you re-installed your new valve cover, did you use RTV along the front corners? Was it torqued properly in the correct sequence? The BMW I6 requires some RTV at these points otherwise, it will leak. See the Beisansystems website for the DIY.
