If timing chain is spun on a 87 Oldsmobile cutlass Calais with the 3.0L would engine valve damage occur?

In most cases no. But if you have tryed to start it alot it could happen. It is hooked to an automatic trans so the motor will not keep turning. You should be fine just changing the chain and guides and tention guide. Also make sure you time it right so no damage will happen. The best thing to do is turn it over by hand first before try to start it.
