Time-Sert for timing chain guide in head?

[pgrandst]

Can I use a time-sert here?

Yes. Helicoil also will be good.

I had the same one crap out on me, and I used a helicoil on it. The main cause of the failure seems to be people using the updated plastic guide and the old 40mm long cap screw. It turns out that the updated guide requires the use of a 45mm long cap screw since the adjuster sleeve is longer.

Mine was loose for a good couple of months it turns out. When I finally went in there to check that the rattling noise was, I found that the steel cap screw had nearly worn itself through the aluminum upper cover lol.
