Car stopped running today out of the blue. Only getting spark at one plug wire when cranking engine. I suspect timing belt is no longer turning cam. I am pretty good with motors but this would be my first BMW timing belt if that is what it is. Anyone done this on this model? Should I run it to a shop or is it worth the trouble? I'm not a novice at cars.
If your not a novice at cars, why not take off the oil filler cap and see if the cam is actually turning. If not, you now have a bunch of bent valves. If it is turning, maybe check the cap and rotor.

You could say "A broken timing belt [might] means bent valves." I've had a broken belt on an interference engine and it's fine. It's a matter of luck many won't get as the odds are against you.
Update Sunday. I have parts to pick up today. Belt and tensioner. I am preparing for pulling the head, but will go for replacing these two parts and go from there.

We have a running engine. Boy does it run bad though. At half throttle she'll run. I would suspect at
180 degrees off, that it wont runn at all, so I think course timing is right. Any suggestions? am I a tooth off?Oh NO backfires...so I guess I'm ok there.

Some engines will run with the distributor 180 off, not well, but they will chug along under no load.

You will probably find the valves are all bent too.

Update: yes. 7 Valves were bent. Some of the rockers also. I am replacing them all. I have gaskets and am almost ready to go. I attempted to get a used cam and they kept arriving broken via uPS. I finally got a good one of those and I should be going back together monday night or into tuesday night.
I was in an accident in my 95 Chevy (ehich this group helped me fix fuel leaks on earlier in the year) and it is reportedly totalled but I think I can fix it up myself and keep her. So I am busy but now getting back to the Beemer! I'll give a report soon on its status.
