Zuke DF140 issue....
Need some advice on issue or who to go to. 2004 df140, had some oil/fuel in cooling water last time out. Immediately thought engine oil cooler. Drained all the oil, gear and engine, all looked fine. Replaced engine oil cooler, torqued to specs. Ran on muffs three different times this weekend and stiLL getting a shean of oil/fuel when I collect the cooling water. Thinking bad oil seal under water pump or a failed fuel cooler, unlikely. Any other tjoughts? Thought maybe it was resideal so ran some degreaser soap thought cooling and still getting shean. At wits end and don't want to throw parts at it. Motor runs like a top, no issues whatsoever. Thaks in advance.
