Does anyone put any sealant on their rear-end cover gaskets? I didn't on my 149 and I had a big puddle of oil on the shed floor today. I had just taken the plow off last week and put the tiller on so the bolts were on and off, but everything was torqued back down. I just replaced the gasket this winter so it isn't that old. I plan on putting another new one on in the next week or so but was wondering if anyone puts any kind of gasket sealant on or anything else. Thanks, Nick
