Post subject:  Bonnet Rattle

at certain revs im getting a consistant rattle between the bonnet and the body just under front window here....

any ideas of how to reduce or stop this? i was thinking of putting (jamming) a sliver of rubber in there, but this may not be easy if the bonnet is opened and closed

you could throw some sticky backed foam in the channels

ah good thinking! is that in anyway water proof? or will it need replacing every so often?

There should be a rubber strip in there. It sits on the lip of the gutter.

If you stick a bit of sponge in the channel it will attract moisture and start to rust.

A mate of mine with a roundie put 2 short pieces ( 2'' ) of pinchweld ,i think they call it ,( it;s the same stuff that goes around the doors less the rubber) ,on the lip at the top or backside of the bonnet, could be worth a try.

also a very good point

i think ill try my local hardware shop for some sticky rubber

there is nothing in the gutter or on the lip so im assuming thats why im getting that rattle

The proper bit was called "Channel- Bonnet drain" Part number HYB3743.

It was like a bit of pinchweld with a lip pointing up.

The roundies had a bit of sponge (8x13?) in the channel. Even my 3/70 car has it. That moulded one in the pic is a Clubby thing... :lol:

Try a lump of wood and a big ratchet strap over it :D :D
seriously a strip of "U" shaped rubber woks well. I have heaps of rubber similar to the style that Morris 1100 showed but does not have the little lip. Pm and I will give you some
