Hyundai has standard torque values based on thread size and pitch. But I probably just used some blue loctite and gave it two uggas..

The head marks 4 and 7 are wrong in the pic for the US market It should be 8 and 10. This points to the hardness of the bolt.

Ok thanks so i belive this is M8 =25 Nm
The Chain guides are 11 Nm i belive, just that marking got me really god today and they don't have this bolt explicitly shown on a diagram

Still have to wait for the MLA / valve buckets - i have to say shimming the whole motor gets relay expensive if your in poor purchasing power country :)

Yes it's ridiculous. Last car I had I shimmed was a Ford 3.4L 32V V8 with Yamaha heads, shims on top of buckets. But Ford did not have the shims. Had to find some used ones that people had collected and use them. PITA as you really don't know what you need until you remove and measure then have to find the right size. Found out I could have used some motorcycle shims though and they were readily available.

But now they use the whole bucket as a shim.
