It’s starting to look like an engine again –

Earlier today, I borrowed Fordboy’s dial bridge and checked piston pop-up. It’s supposed to be +.008. The number’s I got were as follows –
1. .0075
2. .0065
3. .0065
4. .0055
Well, not quite what I was hoping for, but the 1 and 4 were the outliers. Fordboy convinced me there was insufficient wear to worry about swapping around the two assemblies, so I did, bringing #1 to .007, and # 4 to .0065.

It’s not that I really need the extra thou for additional compression in the 4 hole, it’s more an issue of limiting the variables come time to set up the cam.
Which brings us to this little conundrum. A few months back, I posted up a video of the timing chain and the amount of slack it had. I needed to come up with a way of tensioning the chain in a pretty limited area.
Which led me to the dark side.
Now you’re probably asking yourself, “He’s already working on a BMC engine – how much darker could it possibly get?”

That’s a tensioner for a TR3.
Although now that I'm looking at it, I should probably put the anchor down toward the crank.
