Ok so I was cleaning my engine bay and I noticed the oil refill tube was loose so I tighten it and decide to take a look under the cap. I find this rusty colored scum inside the cap and down in the tube, it also smelled like fuel. Do I have a problem on my hands or is this normal? Thanks

may have a head gasket leak, keep an eye on it.

 

is right... fuel in the oil is no good. Possible blow-by or head gasket ? May want to check compression.

 

I have the same problem. I don't recall it smelling like gas, but my neighbor said it is just normal combustion and crankshaft gasses. I don't know, I'm not too concerned about it.
