I have a BX2230 with less than 2000 hours on it. While using it the other day, I noticed a puddle of engine oil under the motor. After removing the engine cowling to be able to see, it appears that the oil is squirting out around the front main seal. Has anyone had this problem, and is there something more serious than a bad seal, such as excessive blowby past the rings? Also, is there a front cover on the engine that must be removed in order to replace the seal, after the engine has been removed? Any help will be appreciated.
