I just changed my spark plugs today and as soon as i turned the car on it started smoking a lot more then normal. Anyway i let the car idle for a bit and it stopped smoking but as soon as i started revving the engine more smoke poured out!! I dont know if this makes any difference but my last plugs looked corroded when i took them out. Anyway is this normal or is something wrong??

 

I'm guessing your new sparkplugs are working better and are now burning all the oil that is in the engine. Your engine is old and tired so be nice to it.

 

i second the above
