The spec limits are +/- 6, so yes, it is something to worry about.

Often chain rails need to be changed to correct this issue. They tend to wear down eventually.

Not hard with the engine out. More difficult with it in. It entails removing the cam covers after locking down the cams with a special tool. I'm sure there must be videos of this. You need to be fairly good at wrenching. I have done it but it was before I had my YouTube channel so I didn't film it.
