After a recent engine rebuild, I need to add a quart of oil about every 800 to 900 miles. I have about 2,800 miles on the engine now and a bit concerned. I hear engine knock at about 1200RPM and after the engine is good and warm. Most recently I have noticed an occasional puff of white smoke coming out of both tail pipes(hard acceleration). I changed the PCV valve to the Motorcraft about 2 weeks ago, just to make sure that wasn't the problem.
Could this be a stem seal problem? Anything else?
I have also ordered a new knock sensor from Ford.
