Agree it pays to check oil level regularly. Another cause for oil increasing is mechanical fuel pump diaphragm leaking diesel into the oil. (Got the t shirt) apparently is not an uncommon issue with Yanmars

If the level starts going UP do not start the engine! There is water in the sump lifting the oil. I had a ski boat that would gain a few quarts of water sitting for a week and we put a pan under the engine and drained the water out before we started it. Running it makes an oatmeal mush that does not really lubricate and wrecks the engine. Joe Della Barba Coquina C&C 35 MK I www.dellabarba.com
