first oil change, now weird noises...

I hope you aren't experiencing the rear crankshaft oil seal howl.... due to
a bad seal... these seals are known as prone to go south if the engine gets
overfilled with oil and if they are too old....


I hope that ain't your case, otherwise it's very uncool........
