You appear to be doing a lovely job, Graham, and I wish you well with it.

I really envy the amount of space that you have around the engine bay. In my old Anglebox with a pre-crossflow engine, to get the engine out, or even replace a head-gasket, I would have to remove the twin Webers on their manifolds and the exhaust manifold. And the only way to hold them in place required Allen bolts using a long handle key turning about a quarter of a turn at a time. Not a job that could be done when the engine was hot without seriously burning my hand as I was the only one with hands small enough to get in the gap between the manifolds and the side of the engine bay.

In hindsight, when I had the wheel arches modified to take the wide wheels I ran, I should have got them to make some modification to the side wall to make it easy. As it was, as it took so long to get the head off, I had to scratch from the final of a cup race that I qualified for it in the heat earlier that afternoon, blowing the head-gasket as I crossed the finishing line.

Thank you.
The flat 6 engine is huge but the layout makes it easy to work on and it is beautifully engineered, lots of dowls and sleeves to ensure a precise fit.


Generally, the thinking is 40 hours to disassemble and clean and measure.
40 hours to build up, so 80 hours and a specialist @?100/hour and the engines can cost a great amount!


I love this kind of DIY, cheap too, but the parts and services will still be a Big Bill. Mrs Hillclimber still on-board.
Phew!

My engine wouldn't have been what you could call anything near being well engineered. I was lucky that a local engine engineering business worked on the steel crank and camshaft as well as boring the cylinders and shaving the head. They also, at almost cost, supplied all the gaskets and bearings that I needed which was very helpful.


Being as how stressed the engine was, I took the decision to change the head gasket after every race, and completely rebuilt the engine after every other race, so approximately every fortnight and every month during the season of about 8 months. We would dismantle on the Sunday night when we got back, and re-assemble on the Friday night before the race, often all nighters - I would do the build, and my helpers would do the install, leaving the carbs and exhaust for me to do in the morning before we set off to Brands to "run in" the engine.

Luckily, 4 pot Ford pushrod engines are pretty easy to dismantle and put together, but getting the Webers back on could take at least a couple of hours, usually longer than the re-build itself.
