Have used the tractor quite a bit after changing the oil and filter. The oil level is always on full and doesn't gain any at any time. The tractor does oil the top part of the engine real good and when it did run the oil out it did come out the top of the engine thru the cap on the valve cover and run down the side of the engine. Cannot add oil thru the cap in the top of the valve cover. Have to add it thru the Dip Stick. Strange, but thanks for the info that you gave me. Seems to be great now. Could a faulty oil filter have been the culprit? Thanks Len
