:( I disassembled the head on my 83-300D today and I have an obviously bent valve. My question is; how do I check the rest of the valves to see if there straight?

You could spin each one in a drill press or an electic drill clamped to a vise.
How did the valve get bent? What a drag.

You'll be having the valves ground when you have the head reworked right? They'll let u know if a valve(s) are not servicable due to warpage.

The complete story of how I bent the valve is posted under the title "83-300D engine question" on page two. But basicly I broke the timing chin at 60MPH. :( :( :(

Jay was wondering if you had any symtoms to the chain breaking before hand or did it just break? Was the tach fluctuating?

Does you model have a double chain? Does anyone know what model do? Does mine?

Mattsuzie, I had no warning that the timing chain was going to break, BUT I new it was worn and I bought a new chain,BUT I broke my foot and didn't get around to doing the job. My tach was working OK. My 300D dose have a double chain. I know that the 83-360SL had a single chain as I had look at buying one. I seem to remember that the 80to83 360 engine cars had a single chain, BUT I don't know that for sure.
