how much are these roll over valves? where are they located ?? i have a small leak somewhere, CEL is on…don't smell gas yet r…
FWIW-- not sure this helps but I am sure it can't hurt. I always raise the rear deck lid on the Modena after a drive and pulling it into the garage. The heat from that engine bay with the deck lid raised will significantly heat up the entire 2 car garage several degrees. I have to think that this helps the plastic, rubber, and other "expendables" live a little longer.
Had samevpronlem with BMW. Dealer couldn't figure it out. Went to MrMuffler!!! They injected spark plug cleaner and problem solved. It's called TERRA CLEAN. 150.00. BMW changed sensor 3 times and still lit. Then they suggested change of catalyser. 2000.00 but would not garantee if it worked....then i wentbto an expert in exhausts. But it could be anything.
