Oil smell draft

[guyzoun]

I own a Nytro 2007 with 6000 miles on it. Lately, I have noticed that every time I come to a stop then accelerate moderately to 20-30 mph, I get this annoying oil smell draft.

I open up the air box, and noticed small pieces of yellowish ice. These pieces of ice are contaminated with oil. Same smell as mentioned above.

As well the foam filter has turned yellowish/gold. It is as well contaminated with oil. Well, looks like considerable amount of engine oil gets sucked in the air box.

I suspect this oil draft is coming from the air box. But what is the root cause???

We have 2 other Nytros 2007 and a Vector 2007 that don't have this situation.

Thx for your advice, inputs.

do you like to carve and boondock?
If so it might just b comming out of th oil breather

Is the oil level correct? Could it be too full? (e.g. checking the oil with the dip stick fully screwed in?)

 

[SnOrIdEr]

you are not supposed to screw it in, did you chek it cold though?

So, ... Guyzoun, ...

What did you figure out here?

Are you sure its motor oil smell and not gear oil from your chainecase venting after a hard ride, we APEX owners experience GEAR oil smell after a good and long high speed drive, it gets very hot and releases a strong smell...

Oil level is fine. (Unscrew dip stick)

Cleaned the air box. Oil residue in there. Foam is dirty with oil stain.

6200 miles, leaving for another 4 days trip thursday.

runs 18.5 miles a gallon. My 2 brothers Nytro average 21 miles per gallon and no smell.

Thx for inputs

yes, cold! Oil level is perfect.

 

[Len Todd]

You check the oil level when the engine is at operating temp, not when it is cold. If you check it when cold, it will be high when operating. This could be your problem.

 

[SnOrIdEr]

The reason you check it hot is cause it expands

 

[attakred06]

you are supose to check oil with gage fully screew in.

 

[attakred06]

check owners book

 

[SnOrIdEr]
