a friend has a 04 600 that seems to be getting coolant in the oil. On the last trail ride I drained a few ounces of oil cause it was high.Well we got back /about 100 miles/ its up the dipstick a good 1.5 inches again. Were is a good place to start looking for a bad seal or gasket? I havent had time to research this problem so any ideas would help. Thanx!

 

it will mostlikly be a bad head gasket but it could be anything from a bad waterpump seal, to a cracked cylinder or head. good luck
