FYI: Bad Crankshaft Balancer Info
Well my balancer finally came apart on my 92 ssei. It started with a small rattle at idle, I didn't think much of it. After 10 miles of driving, I came to a stoplight and it sounded like there were ball bearings in the engine.
At first I thought maybe it was the supercharger, then my attention turned to the power steering pump because the sound changed when I steered the car.
The sound was only there at idle, it went away after about 1500 rpm.
The way I figured it out was that I found it made the noise (although it was different) no matter which belt I had on the car.
The rubber was completely torn away. The balancer has a hard stop in it, so that when this happens you are metal to metal. This makes a resounding "clunk" when you start the car. It'* scary until you know what it is.
I have read about a new balancer design, I am not sure if I got a new design or not, it looked slightly different, but not vastly different. But then again who cares, this one lasted 12 years !!
I decided to change the oil seal while I was in there. It'* not that easy to do, so I wouldn't advise changing it unless you really need to. Without the special tool, getting that seal started in the bore is tough.
A word to the wise: Check the three threaded holes in the new balancer before you install it. This is your only way to get the balancer back off, and you want them to be usable. It turns out that the metal webs on my new one were ever so slightly in the way, and I couldn't get bolts threaded all the way in. A tap run through from the backside cleared up that problem. So now if I ever have to pull it, I know I can. Also, this one pressed on a lot harder than the old one ever did, but It should come back off ok.
