I got my 91 GT about 3 years ago and its always used more oil than a typical car but never nothing too radical. I'm from Georgia and go to school in Ohio so during the summers I bring it up here to cruise while the weathers nice so its made some long trips since I've had it. I just drove it down to GA for my week of summer break and back up to Ohio and now everytime I go to fill it up.. it needs a quart of oil to go right along with it.

I've never cracked open the motor on this car. I knew it had been beat on by the guy before me so I never bothered and started a 351 project without even considering if it was good or not. The 351 is not near completion enough that I could have it ready to go soon (I'm taking the time and money to put the works in it). Anyways, once I got back to Ohio there was oil residue around the tips of the tailpipes and it smokes when I start it sometimes. My 2 guesses are that 1) the valve seats are worn or 2) the piston rings are shot. I'm just looking for a little bit of knowledge on this subject if anyones had the same ordeal, and I'm sure some have. What say thee, Mustang Forums?

The oil loss during highway cruising would point to the rings. But blue smoke on start up points to the valve guides. I'd say you have both.

just rebuild the motor

I think you skipped over that I'm in college. Money is not abundant.. and also, I drove this from GA. Its the only car I have with me. It can't be down for too long.

actually...
blue smoke on...
Acceleration - rings
engine braking - valve guides
initial start up - valve seals


not the "rules" but a pretty good set of guidelines

yeah so.........when do you think I rebuilt my first 302??? and I can redo a 302 /overhaul one for under 500 beans....last one I did cost 382.00 beans to cut the small ridge on the cylinder wall, hone it , added new bearings and rings and seals on heads and new oil pump and all new gaskets and I sold it to a friend when done and it did not smoke or burn a drop of oil and he used it in his weekly braket racer for 3 years and had 400+ passes on it and it was a 100k grand marquis motor I scuffed and dipped and painted blue and called it new!!

Alright, sounding good. Got any links to some decent rings, seals, and gaskets? Far as I know its the standard bore and heads.

To just get the thing back to GA.. would these piston rings cut it for now?

those brand rings are exactly what I used, however those are .040 over , you need just the standard bore e251's
