I think this might be the first time I haven't had to add another problem to the ever-growing list of things to fix haha. I will point out, however, that around the rest of the box it does touch the engine. Maybe the gasket is getting a bit old? I've currently got a decent oil leak, but it looks like it's the valve gasket and its getting done when the parts arrive.Normal, the gasket is rubber and does not fully compress when fitted
