Does it do the basics and keep most of the water out of the spark plug hole, which is all I'm hoping for, having seen the state of my spark plugs which had clearly been immersed in water at some point. A simple cover like this was all Morgan had to do when building the car. I'm might put some Morgan branding on it before I fit it.
Yes it does but it's not 100% watertight, but much better than nothing.
I watched the installation video from the supplier’s site. Pity that it is only secured by two screws at the front end, where there happen to be a couple of convenient holes. The rear end is free to bend and you have to be careful to keep the plug leads well down into the well to avoid the cover being banana’d back up at the coil end. The material is not that rigid.
Although the plate is nicely made to fit, there is absolutely no seal between it and the rocker cover. As water always finds a way, I look at this as a nice cosmetic addition but unlikely to be as good as a full cover.
Incidentally, it is well documented that rusty sparking plugs are common on Duratec engines whether in a Morgan, Mondeo or Focus.
Although water ingress is highly suspect, I also point the finger at condensation forming in those deep pockets.
