That's not really anything new, is it?

Oh, thats so Y2Kish.

Greg, you didn't think you were telling us something new did you?

its because they use forged pistons and they make noise when cold starting then when they warm up they expand and no more noise. I would rather hear that noise and know they used good components then not hear the noise and they use some cheap and weak cast pistons.

Anytime I see a car speuing out blue smoke, 9 times out of 10, it's a Ford/Mercury, many times a taurus or Mercury's version of it.

I had a 2002 6.0 gasser and had zero problems with it. But I still believe it's a big issue...
