I left off with a teaser photo of the aluminium engine cover.
This is a good idea with the 4 cylinder because rain can enter through the louvres and collect between the cam covers, and on the coil pack. I started off with a sheet of 1.2mm aluminium.
It's necessary to make a hole for the oil filler.
Initially I was going to use the tapped holes in the cam cover to secure this, but decided there was another way.........
Here it's just resting on the engine.


I decided to contour the cover and to fix it to the stainless water hose using U bolts.

Here is the shaping gear.........
The wooden blocks were a really useful addition.......

This is the trial fit of the brackets.......

And this is the final spec, with neoprene.

Test fitted, corners rounded off..........


And finally, I added edging - it looks better, even though the water will have to climb over the edge. On the trailing edge, I've turned the edge up, and used thicker edging to keep water off the coilpack.



The test will come in summer, if the cover retains too much heat. We'll have to wait & see!
