Nice one mate. Went to Vauxhall to grab a gasket for the manifold I have and it's the same as the Vectra C Z22SE gasket. I'm feeling confident it will fit!
However, I'm still confused as to what the hell my manicat is. It has Z22SE/Z22YH stamped on it below the Lexmaul logo. I've been told by the company I purchased it from it's for a Zafira A/Astra G. However according to Vauxhall the only 22SE/YH application to come with the manicat was the Vectra C.
Really confused as to what this manicat is for!
