The leak is from a long pole like steam that starts at the cross over pipe that leads up by the cam housing and is caped off? Aparently this steam broke at the base causing the exhaust to leak out. Does anyone know what the part number is on this item and what it is used for? I could not find this thing on my second 951?

Thanks

 

Thats the O2 test tube, just take it off and cap with a lug nut.
