Loctite 660 retaining compound will secure the sleeve if it ends up being a non-interference (press) fit. A company with a generic installation video can be found on Youtube...they sell a nice sleeve-installation tool. Can't think of them right now, but they're easy to find. I will machine my own. **Q: Will this fit a 1997 8.3 Cummins** A: no ,it won't fit **Q: Which side does the rubber seal go? I’m guessing outside** A: Best thing to do is watch a YouTube video over it that’s what I did and the seal goes on the outside if I remember correctly **Q: Will the part fit a 6.7?** A: Yes ,it will ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality n price *by on Reviewed in the United States January 19, 2026* Fit tight n good material see how long they will hold up ### ⭐⭐⭐⭐⭐ Good product! *by on Reviewed in the United States December 13, 2025* 2-years later, the truck still doesn't leak.
