Hello viewers, I had a problem with exhaust manifold leaks on this John Deere 8.1L engine and documented the process of removal, upgrade to the "longer bolts with spacers" solution, and reinstallation. I believe this process would apply to all 10 Series tractors which use the 8.1L such as the 8110, 8210, 8310, 8410, etc.... but may also apply to older and newer vintages of tractor using this same engine platform. I hope this video is able to help someone who has experienced this same issue on their Deere.
