When I press on my gas real hard a puff of white smoke comes from my exhaust. I put Seafoam in my crankcase and drove about 150 miles and changed my oil. I doubt that would be the problem now. I put Seafoam in my other BMW's and did not have this problem.
It only smokes when I press hard on the gas.
I did the following repairs.
Replace all ignition coils and spark plugs
New valve cover with gasket
6 New fuel injectors
4 new oxygen sensors
new breather hose
All parts are genuine BMW parts.
Any ideas?
white smoke typically indicates coolant... but not always
black smoke is usually fuel
bluish smoke is usually oil.
does car use coolant?
now, you said white smoke are you sure its not just steam, when you press hard on accelerator my car will "get rid" of the condensation in the mufflers and such in form of water vapor and steam like vapor.

If you are pressing hard on the gas pedal, it’s most likely the turbos... when they on on their way out they burn oil and gives you the white plumes of smoke only when accelerating hard-ish.
How many miles does your car have? Turbos need replacing about 100k or so depending on driving style.
