Hello everyone. I'm in need of your help. Here's the deal...

I was recently sitting at a stoplight and when it turned green, I accelerated, and then the car just died. Had it towed home. From what I've read about my experience, everything points to the timing belt. So, I'm checking into that. Anyway, I've got the top timing belt cover off, and I've been turning the crank. There are 2 teeth missing on the belt, but it is still very tight and in place. So now, I'm wondering if it perhaps slipped.

So now, I'm trying to find TDC so I can see if the marks on the cam gear line up right. I've been turning the crank a bit, looking in the little window between bell housing and engine for the TDC mark (haven't found it yet - I'd still be at it, but my car is parked on the street and it's dark now). Anyway, I wound up taking the distributor cap off just to check out the orientation of the rotor. When I took off the cover, I noticed there was quite a bit (like say about 1/2 tsp) of finely ground metal ground so finely it was almost powder. I dumped that out of the distributor cap. The point here is that something inside the distributor has been wearing BADLY. I've never seen anything like this before, and it obviously points to either a current or future problem. Anybody have any guesses as to where all of these powdery metal grounds came from?

Thanks.

By the way, my car is a 1987 LXI - fuel injected, manual trans.

take the number one spark plug out and use a screwdriver to find tdc at least thats what we used to do on the old chevy v8's
also u prolly just need a new cap and rotor for the dizzy

Also make sure you spin the engine over by hand by using a 19mm socket i believe, and put it onto the crank pulley bolt and use a ratchet to spin the engine over.

Your flywheel is probably covered in oil like mine was. I coudln't find the timing marks until I took it out and cleaned it off. If you can find some creative way to clean it up, you'll probably be able to find it.

Turns out my distributor was absolutely toasted inside. I got a new/rebuilt one and put it on tonight. I didn't really have time to mess with it after that. I was disappointed that it didn't start right up after I put it on.

Any tips on setting the timing? I can see that the distributor is set up to be able to rotate a few degrees.

Thanks.
