cod 117 #1 Posted April 26, 2015 Not sure how often it happens but last Friday I noticed an occasional puff of blue smoke that seemed to coming out from behind the muffler on my 418. Luckily I only had a couple of more passes to go to finish up and once I was done I had a chance to investigate and I noticed that the back of the engine around the oil sensor was rather oily. Managed to roll the beast into the garage and found out that to really see things more clearly the shrouds had to come off. Too bad Kohler couldn't find a better way to shroud it that didn't require 20 bolts... Anyway got the sensor exposed and after wiping down the area, I fired her up and was found that there was a leak where plastic of the sensor meets the metal half. Fortunately Jack's had one in stock and it's fixed now, I'm also getting better at getting the shroud off and on although I wish Kohler had used 5/16 or larger bolts as it's too easy to strip the 1/4 ones.
