[QUOTE="2drx4, post: 129008, member: 23729"] I've found references to Mitsubishi engines in general having issues with leaking guide seals. I wonder if a competent engine machine shop can just drive in and ream a universal guide that takes a modern seal instead of whatever contraption Mitsubishi came up with? It is done often on some older engines. If I was super lucky, and I certainly am not, this engine might just need valve guide seals, a quick dingleball hone on the cylinders, and some fresh rings. As to those repair seals (Flaretite), there's an aviation standard part that's basically the same thing, I'd have to look in my notes to find what the P/N are (not that anyone cares). They work okay, more something we'd use if the one part was not able to be procured or replacing it wasn't possible at that time. If you do get it together with them and it doesn't leak, I recommend never touching it again until you have new parts. Thanks for the info though! Still pretty torn on what to think about this, I'm thinking the seller looked into what a cluster it is to find parts and info to rebuild the engine and that has resulted in his decision to sell it for what he has it listed for (way less than any other modern skidsteer listed, and actually less than a beat up old 610 even).
