nytro oil tank vent line

White Whale · Mar 27, 2011

I just installed the Yamaha roll over valve on my 2010 MTX, and am wondering where everyone is routing the vent line that comes off the back side of the valve. Suggestions and pics would be helpful.

Thanks

I just spliced in the valve and left the vent line running into the intake box

On Stock sleds it's routed to the air box like KJFarmer mentioned.
On boosted sleds depending on who's kit it is, most of them run a long hose down torwards the belly pan.

On a boosted sled what is the reason for running a longer hose down to the belly pan?

This sled has the 180 hp MPI kit, so the air box is not there. I will try to run the hose down to the belly pan.

Thanks

On boosted sleds there can be a small amount of oil mist/vapor that exits out the breather during boost conditions. This is because of the much higher cylinder pressures generated while under boost.
By routing the hose down towards the belly pan, it helps keep the oil mist away from the brake rotor and keep things a little cleaner under the hood.:thumb:

run it through the sub frame hole where it used to go then pop the cap off the subframe tube and stick it in there. No muss no fuss and if it does blow by you wont get anything messy.
