Timing sprocket gear loose against cam key.

Yeah I 100% agree with you unfortunately this timing chain set came with an engine rebuild kit off of eBay the Pistons and bearings and everything already installed so I'm not going to take all that apart to send everything back so I'm kind of screwed that way.
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.
