3:49 oil leaks down from the valve cover and messes up the rubber gasket. That`s why the rubber fails. What you need to do is use silicone also this will keep the oil out.
Need to do a video on specifically where this cam bridge fails and where it leaks and how it causes the water pump mounting o ring to fail ? isnt the cam bridge in the front of the engine ? maybe you meant to say valve cover gasket ?
