Blown top seal blues

#1
I may have started this thread in the wrong section before.
So I have a 6.50 Chipper Shredder Vac by Troy-Bilt that I did a repair of the bottom oil seal.
Also replaced the Magneto due to no spark after I reassembled the entire machine it was still leaking oil from somewhere under the shroud,Could the top oil seal be bad too?
Also if so can this condition cause this second magneto to go bad and can either magneto be repaired?
The oil leak is the only thing the two magneto failures have in common.
Any thoughts or suggestions would help greatly.
Thank you
Terry (Reaper)
