It's the escape route for oil vapors and blow-by gases that form in the crankcase when the engine is running: if the hose hardens, cracks, or kinks, the internal pressure can no longer escape, and the engine starts to \u003cstrong\u003eleak oil from oil seals and gaskets\u003c\/strong\u003e, dirtying the air filter box, and, in the worst cases, spitting oil into the intake. It's a very inexpensive part that almost no one checks, but its failure can lead to much more costly repairs. The original Piaggio shape has pre-formed bends and correct diameters at both ends: when installed instead of a generic hose, it prevents kinks and disconnections.\u003c\/p\u003e\n\n\n\u003ch3

It serves to release the pressure that builds up in the crankcase during engine operation.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eHow do I know if it needs to be replaced?\u003c\/strong\u003e\u003cbr\u003e\nCheck it by hand: if it's hardened, cracked, crushed, or has cuts, it needs to be replaced. Indirect symptoms include oil leaks from oil seals and gaskets, oil stains on the engine, and oily residues accumulated inside the air filter box.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eCan I use a generic rubber hose?\u003c\/strong\u003e\u003cbr\u003e\nIt's better not to. The original has pre-formed bends and correct diameters at both ends: a straight hose cut to size tends to bend, kink, or come off. Given how little the original spare part costs, it's not worth the risk.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eWhich scooters does it fit?\u003c\/strong\u003e\u003cbr\u003e\nThe official Piaggio catalog lists it for Beverly and BV, Carnaby, MP3, X7, X8, X9, and X10, Gilera Nexus and Runner 4T, Aprilia Atlantic, Sport City and SR MAX, Scarabeo with Piaggio engine, and on Vespa Granturismo, GT, GTS and GTV from 125 to 300 cc.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eOil is coming out of the hose: is changing it enough?\u003c\/strong\u003e\u003cbr\u003e\nIf only vapor comes out, that's normal. If liquid oil comes out in significant quantities, the hose is not the cause but a symptom: it means too much blow-by is reaching the crankcase, and the typical causes are worn piston rings or valve guides.
