So getting on the "accelerator ramp" I felt my 4WS kick a little to hard, by the time I looked out the mirror I saw a cloud of smoke and an Oil trail! By the time I got on the shoulder and looked @ the dash the idiot light was illuminating.
Medium strenght threadlocker in the center console @ all times!!!
I got a friend to pick me up @ about 3:30, went to the local dealer, no O-ring, drove to the a dealer w/ 1 in stock ~ 1hour away and was told "it is for a job, not for sale!!!" Then @ 7:15, I found a Hydrolic Repair shop still open and got an O-ring to match. This was the 1st time since I've owned a DSM (um, like 6 years now) that i haven't had a tool kit in my car, FTL. So I got my friend to take me to Pep Boys bought 5 qts of oil and "permanent thread locker." Stopped @ my house and grabbed deep 24mm, strap wrench, A big cardboard box (poor man's disposable creeper), jack and flashlights. I got it all back 2gether and limped her home a couple of miles.
Looks like I need to get a '90 oil housing and an Aftermorket Oil Pressure Gauge. After 6 post '90 DSMs, this is my 1st to have that stud back out.
BTW, the O-ring was in perfect condition. So i spent the rest of the night drinking and shooting a pistol @ my friends.
