What would cause oil to be burning out the exhaust pipe??

Asked by May 21, 2017 at 05:44 PM about the 2006 Ford Fusion S

Question type: Maintenance & Repair

2006 Ford Fusion 2.3 started out by smoking really bad a bluish gray colored
smoke babied it the rest way home.  Talked it over done a lil research
checked oil there was none showing on dipstick and none on the garage floor.
checked valve pan covers they seemed to be fine and then decided to
change out the Pcv valve then put everything back together. Had to add 4 or
5 quarts of oil then started it up.  It started to smoke again and this time oil
was pouring out of the bell housing and on closer inspection I seen that oil
was being sucked out of the block thru the intake at a very rapid rate and
burning it out of the exhaust. What would cause oil to be sucked out of the
block thru the intake and burn it out the exhaust??

I think you have a bad rear main seal and other problems. If you ran it out of oil it is probably junk.

High internal crankcase pressures can cause this, oil starts blowing by all the seals, due to excessive ring clearances or piston problems, as F_O_R stated it most likely needs a new engine to fix all of it's problems.
