    Exhaust smell and white smoke

    I changed the CAT. And put a m3 muffler on my 325i And it stoped smelling a smoking for 3 weeks or so. And now the same smell and white smoke is back?!?What else can I do for it to stop?

      What does it smell like?? White 'smoke' is most likely coolant, and dissipates quickly. HEAVY oil burning(like when someone puts Diesel in a gas engine) is white, but it stinks like oil and hangs around quite a while.

      Does your car consume coolant??

          Well I did a royal purple oil change and change the CAT and put coolant over a month ago. But where I put the coolant , I opened it today and it was still full?

              But the smoke will go away after 5 mins. But when I start my e30 it get really hot quick.

                Sounds like you've got a leak somewhere. When the head on my M20 cracked it started slow like you're saying.
