Timing sprocket gear loose against cam key.

Exactly why I always advise against getting an engine kit. You're subject to someone else's decision of what goes in it. That's about the crappiest timing set money can buy. I've said it time and again. If you don't pay around or over 100 bucks for a timing set, you're gettin a crappy one.
It's an Enginetech, with a Cloyes part number. Crazy thing with almost everything coming out of China, how can we know if the parts come out of the same bin and just get thrown into whichever box that some company pays them to toss it into, Cloyes, Enginetech, Melling etc.
