The early wet-sleeved engines that Deere made only had one sealing ring per sleeve, and this is not adequate for longevity. This includes all the 1010s, 2010s, and early 350s, 450s, etc. The first generation engines, e.g. 1010s and 2010s never got any type of improvement or update. The next generation engine did. Early 350s, 450s, etc. get updated with a special conversion sleeve that allows the use of three seals per sleeve. Also, besides having three seals instead of one, one of those three is a special silicone-rubber that expands as soon as it contacts oil - so it swells up, fits tight, and takes up any gaps. That's why there's a warning never to oil the seals when installing. With the older engines, very often if the block gets drained and they sit dry for a while, what's left of the seals dries out and they fall apart. Many people use an extra sealer when assembling a 1010 or 2010, e.g. red RTV sealant or an equivalent - along with a new seal. It certainly won't make it any worse, and I can't say I've ever heard of one leaking after it was done.
