my 91 towncar is burning more oil than it used to, but then also my overdrive has been out and it runs much higher RPMS on the highway because I can only get to 3rd gear. Does anybody know if the valve stem seals are really hard to change? I dread the complexity of working with the overhead cam setup.
Also, how do I figure out if its the rings or the valves that's causing excess oil consumption? I have been told many times that the blocks on these cars is really reliable and last forever, however I've been driving for like 30k miles without overdrive and so probably I've put alot of wear on the rings from those high rpms on the highway. The car has well over 200k miles on it. Odometer was broken for like 50k miles driving before I got the car and so I don't know the true mileage, could be high 200's
Thanks
