I had a 94 Eldorado sold it with 145K miles, it was an ESC not ETC so I didn't have the touring suspension with all the electronic shocks/struts. The only thing wrong with mine when I traded it in on my Lexus was the dreaded oil pan leak. The fix for this is to pull the engine and transmission to change the O-ring seals and of course when you have it down this far you would also want to reseal the half cases and timesert the heads. I found the northstar engine very easy to work on for the things you could get to. The northstar requires some specific maint procedures that many people just don't understand. My favorite one was the frequent WOT runs to keep the rings exercised. This will keep it from burning oil. The Northstar has an aggressive honing pattern on the cylinder walls to keep the oil in the rings at high RPMS. If you don't run these engines hard the rings get carbon-ed up and stop moving freely in the ring grooves and they will burn oil. Here is what you do, in a safe place drop it down to second gear and leave the shifter there. Floor it and run it right up to just under red line. Check to see if you have a bunch of black soot or smoke coming out of exhaust, you most likely will. Now leaving it in second let off the gas completely and coast down to about 30MPH then floor it again up to just under red line. Do this a couple more times and then at least once a week and you should start to see less oil consumption and no more black smoke/soot from the exhaust. This procedure exercises the rings and gets them moving around in the ring grooves like the should be to keep the oil from getting past them. This is the decarboning procedure that keeps your northstar happy. After this just go WOT getting on the freeway if safe and all will be good. This was a great car and someday I would like to get another one, The power and handling was awesome and the kiddies in the 5.0 mustangs like to get spanked by the big muscle, sleeper Eldorado.
