One of the most common reasons for bent valves is a broken timing chain or belt.
Sounds like you're either not connecting it properly or you've got a defective light.
No, it has a timing chain. Becareful when removing the camshaft, because the chain tends to fall down inside the timing cover, which is not removable from the front. And it's a pain to reset the timing chain back on the crankshaft sprockets (gear teeth).
