Ver well....here is the back ground......94 LS auto, 175k miles.
after a spirited run of about 100 miles, sport mode, 4k to 5k revs mostly, max 5500, then, 5 minutes of slow regular traffic in auto mode. The approach to my house is gently down hill, for about 1/2 mile, mostly on over run or min throttle. Just as I was about to turn into the drive way, the engine stumbled the oil light flashed on and off a couple of times the stayed off. The car stumbled to the garage. Next day I started it up it ran very roughly but on all six, making a sound like a donkey. It seemed the every revolution I was getting a heee haww screech and a lurch. I suspect a spun bearing and will now attempt to fix it. I will start this Sunday and put 3 hours every Sunday until its done...at least that's my plan. I will try to take photos every step and see what happens.
