If you watched the You Tube Video by Ted from Havuk Industires on purchasing and replacing the weak Upper guide bolt, he makes comment near the end that there is also a problem with the Lower guide bolt breaking and he is going to figure out a fix and make a video.
Does anybody know if that ever happened and why wouldn't you replace it at the same time as the upper bolt?

Any other bolt would require removal of the timing cover.

 

I replace lower bolt when replacing timing chain, while the cover is off. But I haven’t seen a different bolt available

 

I have sent an E mail to Havuk Industries. Let you know if I get a reply.
The block he shows in the video had a broken lower bolt showing.
Does the SS 2.0L have the same issues?.

 

I don't recall anyone reporting that this bolt failed, LS, LT, or SS.

 

I’m overly cautious, sometimes, I reuse the bolt if it looks ok, and the upper bolt hasn’t been damaged or the guide broken.
