Interior engine cover

What does the latching mechanism look like? A picture or at least a description would help. Mine has two adjustable latches that you can screw a bolt in to make it tighter to eliminate the gap. I doubt that your cover warped unless your engine runs extremely hot. Did you have an exhaust manifold leak? Another thing to look at is the supporting structure underneath if it is bent somehow the cover wont fit properly. Did your buy it like that or did it all of a sudden develop a gap?
