    The valve in question is situated left hand side of the engine next to the air filter body, there are exhaust gasses leaking from it.
    Some years ago I had to refit the alan bolts as they had fallen out and dropped onto the engine mounting, I now have noticed a small leakage from the valve and I will have to fit a new gasket so I would like the tech name of this valve to order the correct gasket.
    Would be grateful if somebody could reply.
