Daytona Sensor timing / reversion.
 

Hello All,
Has anyone come across a problem with reversion and ignition timing. I changed over to a complete Daytona marines ignition with their rotor for the thunderbolt distributor. I now noticing water in the engine oil it is not coming from any water leaks. It's definitely reversion which started this year after this upgrade just not sure if it's related to the offset distributor rotor causing this or something else. Tested all the cylinders which are around 160 so it's not a bad exhaust valve, any suggestion or anyone run across this problem.
Thanks

The offset rotor is for cap to rotor phasing.

But…..Sure……,incorrect ignition timing could cause reversion.
