I noticed a while ago how flimsy the centre scuttle joint seemed and noted that the overlap of the 2 halves is only a few mm. There was no resistance to water seeping through the joint into the engine. Even though the engine is fitted with the covers etc I would prefer to minimise the water ingress.
I drilled a small hole next to the joint and with the use of a tap washer cut just off centre to make a level base for a number plate fixing screw and cover which brought the scuttle joint together after putting some clear silicon along the joint – making a water resistant joint – see pic.
Not saying that this has prevented all water ingress into the engine compartment but has certainly reduced it along this joint.
