New Mustang! Blowing some smoke.

BrianNV · April 24th, 2007, 12:49 PM

OK, I went and did it. I ended up buying a 1990 GT Mustang for $2800. After driving it around for a couple of days, I noticed an intermittent puff of blue (oil burning) smoke come out the tail pipes when starting from a dead stop.

The motor, from what I was told has about 100k miles on it. When I am cruising around at highway or city driving speeds, I don't see any smoke. Even under full throttle exceleration I don't get any smoke.

So, I am thinking that perhaps a valve guide is worn out. There is some minor valve train noices, but nothing major. I actually hear an exhaust leak more then anything else. Oil pressure seams to be fine throughout the rmp range.

So, I guess the question is, "Is my assumption correct?" Or could it perhaps be that the motor needs a quick refreshing such as; rings, bearings, oil pump, etc? Could worn out rings be the culprit of the oil loading up and causing the smoke?

Yeah oil smoke is white with a faint blue tint.. Anti-freeze smoke is pure white and billowy like a cloud, and is usually always coming out idle, acceleration, deceleration ect...

Hey you gonna be out this Fri or Sat?
