My post very smilier to a recent post by Kurb that Grumpy helped. (Thank you both for that post, it gave me confidence to proceed!)
I too have Honda HRB215 SXA lawnmower with GXV140 engine, more than 10 years old. The motor starts and runs perfectly. However just this year the engine is releasing oil from somewhere under the flywheel. It is possible that I put too much oil in the mower this past Spring.
My first effort was to replace the oil pan gasket as well as the cylinder head cover gasket, but when I put it all back together again still had the same issue. With the mower all nice and clean, I found that almost a mist of oil was covering the whole top of the deck within a couple minutes of running.
In my second effort, I have managed to get the flywheel off and upon inspection I am not sure what to do next. The top "seal" looks okay, and the breather assembly had oil in it but it did not look like it would leak from there. Any suggestions to help identify the source?
If the crank shaft upper seal is the most likely, should I replace anything else at the same time?
