i guess this is another very common problem with them...makes me now agree they are POSs , mine had RMS & IMS done before
This can be caused by a broken slide rail. If the part comes between chain and chain wheel and is big enough and is not crunched the engine housing can burst. In general this is not a common problem with 986/996 engines, but we had this problem over here in germany 2 times.

Earlier 944/968 englines have broken chain rails as a common problem. But maybe it can be a 986/996 problem in the future. The plastic of the slide rails will not last forever and they definetely will get worn.
