Obscure 2004 Yamaha F225TXRC Question - Fuel in my oil
In a healthy engine, Is there any way for fuel to get into the crankcase oil besides passing through the 6 injectors? My engine appears to be "making oil" even when just turning the key into the "on" position without even cranking OR running the engine. Leading me to believe one of my electric fuel pumps may be involved in the situation? Thanks for any insight you can give me on this.
What I have already done:
New thermostats and thermostat housings
Cleaned fuel injectors and replaced all rubber o-rings
Replaced 2 fuel filters
Replaced Oil filter - twice now
Put in 6 new spark plugs
Checked compression (All good all 150)
Completely drained oil multiple times and replaced - getting expensive.
When I did run engine briefly, it purred like a kitten... And yet problem continues...
