I have my rig in the shop with an oil leak after noticing an oil slick last time out around the engine. Ironically timed perfectly just south of the 20hr service interval @ 18hrs. Took it in for a "twofer", 20hr service and oil leak. Diagnosis is a leak at the base of the dipstick tube. Service tech replaced the tube, o-ring(s), and grommet (under warranty of course). However, stated that they had never seen the issue before. I'm looking to see if anyone here is familiar with or experienced the same situation. Wanting to get a good feeling that there is not something else going on that caused the problem. It's go time and I don't want my rig sitting at the shop!! SN#3B056732
