Ford Fusion - cylinder head cover refitting - mattjb

I've been attempting to access the injectors on my 1.4 tdci fusion. It was necessary to remove the cylinder head cover but now I'm having issues refitting it. It doesn't seem to sit nicely with a definite lift at the back. I can't see anything trapped and I didn't want to just start torquing it up hoping for the best. Would it be the manifold seals ? Thanks, Matt.
