hi all, i recently got my SL350 going after 30 years parked, and found in the process, an amount of rubber inside the crankcase near the oilpump. after searching the forum yesterday i found a post where someone had found a small piece of rubber in the same spot and it was concluded that it was off the camchain tensioner roller. i have part dismantled the engine enough to see that the roller has lost the complete shoulder section of both sides but the central raised section is okay. i have no idea why it would have disintegrated like that, maybe the years in storage, but my question is, could one be fabricated from nylon stock. turned to spec on a lathe. i know this part is very common to over 100 different Honda models and should be readily accessible, but i like manufacturing things like this and thought it could be a good option. love to hear your thoughts.
