I'm working on my wife's 2017 GMC Sierra 6.2 and the #8 exhaust lifter is stuck in the lifter bore. I saw a slide hammer type lifter puller in one of your videos but I don't see it on your website, is it available for purchase? Is the cam likely damaged at this point?

Not sure how I missed this post, sorry bud. Hopefully not too late. That looks fairly nasty from what I can tell. Did the pin come loose for the roller or something? Looking like you need to replace the camshaft but my concern is that lifter bore. I'd have to see some better pictures to know if the tool could fix it good enough. The tool would clean it up but if there is scratches too deep you will have oil pressure loss there.
I actually finally got it out but it's in pretty bad shape. The lifter bore took some damage but I think would clean up with your lifter bore tool? The cam I'm more worried about. What are your recommendations?
