Engine noise- stuck lifter?

My heads have those grinding marks too. They are from the finishing work done at the factory to remove casting flashing during production. From what I can see nothing to worry about.

Please confirm that this loose chain guide in the video is not supposed to be loose ..? and how did you tighten it ?... because the wear strip is a separate piece and ......was it damaged? what caused the marks on the chain ? etc...

And ultimately was this the cause of your noise? or just additional issue ?

Hoping you find answers and get it resolved

Thanks

It wasn?t really that loose when I took the cam cover off. I did not figure out what the cause of the noise is. I?m in the process of putting the cam covers back on. The passenger side is very difficult to get back on!

did you re-secure / Tighten the chain guide ? is it bolted in or screwed in ?

Update on this. I changed the oil and sent the sample out. I think at this point I?ll just run for it 500-1000 miles next summer and send off for another analysis.
