Look at that. I bet you wish you’d got your own twinkly bar stool for Christmas too, don’t you? For some time I’ve wanted one of these in the garage and Anthea bought me one for Christmas, which I think came from that purveyor of fine quality garage items known as Argos.

It’s Christmas Eve (I wish this time of year was still as magical as it was when I was a child) and I’m stretching out the time until Santa arrives by writing this post. Not that there’s much to write about to be honest.
With the engine in bits I could suspend my disappointment and get on with other things. First up is to sort the wishbones that I’ve been meaning to remake. This is to get rid of the Delrin bearings, which haven’t really worked, and hopefully to get a bit of weight out. So, making my usual MDF and bracket jigs I remade the rear upper wishbones, as seen here. You’re right, they’re awfully short (although you have to add a lot of length in the rod-ends to this photo) and this is what completely re-designing the rear of the car would have sorted. However, I just don’t have the time, especially as I’ve just got a new job. (As well as still teaching, this time to “Engineering Doctorate” students, up at York and my PhD viva being next week. Eeeek.)
I took the crank up to Andy yesterday to see what he thought. As I was beginning to suspect he reckoned that the #2 and #3 big end journals were toast. This is a real bugger, as you can’t get undersized shells and therefore can’t get the crank reground.
Finally, I was getting to the root of the problem. And, indeed, demonstrating that it really was a problem. First thing, though, was to close up the top of the engine. So, I took off all the cams and drive gubbins, put the followers somewhere neat and tidy and put the cam cover back on. All this so I I could up-end the engine without the followers falling out. What’s more, with the cams out I can twizzle the crank around as I want without worrying about the pistons bashing into any valves.
