I was thinking about doing an oil sight glass on the clutch cover while I have it off for a clutch replacement and oil cooler install, but I'm not finding a great place to put it. I figure along one of the three indentations on the bottom, probably the one below the dipstick, but each place will have a bit of a lip from the indent. Has anyone done this here and have some tips? Is it worth doing? Where did you place it?

Also I haven't had my cover off for a bit and am not 100% how much clearance these spots have. And do you think the included gasket is fine, or should I go find a proper o-ring+RTV? (I'm worried it might melt)
