Been looking at some vintage Camaro underbody photos and noticed some of the flywheels do not have covers on them. I've recently put a flywheel cover on my Camaro because there was not one on it when I bought it last year. I spoke with a couple enthusiasts who claim that the reason the cover is off is due to the heat factor, ya know causing unnecessary and possibly damaging heat inside flywheel / torque convertor body. Well...the cover is to keep debris from entering and damaging the flywheel gears, etc. Plus there was one on when the factory made the car so... Any opinions or facts anyone may know of on whether or not a flywheel cover should be on (or off) of the car?
