190 E timing chain
A guy at work gave me his 1984 190E. One problem, he said the timing chain broke. I can see through the oil cap that the chain is not broken but seems to have slipped out of the sprocket grooves up onto the top of the teeth. Of course it does't run. Is this common? due to chain stretch. And is the 2.3 a contact engine, what am I possably in store for. I did get the car for free so if it can be fixed and be reliable it would be worth it. Any help would help, thanks.
