Bugger!

Was that running on points?

No. That was running with the coil away from the heat and the distributor earthed properly. Points would be the next attempt, had I not ballsed it up.

Chaps, is it advisable to replace a single inlet manifold bolt, that's if I can get the broken one out, or does the manifold need to come off?

If you can get it out without removing the manifold then just replace it. Presumably none of the other bolts were overtorqued?

No. After snapping the first one I threw the torque wrench down the drive and realised I had miscalculated. I'm so annoyed with myself.

The broken portion is too recessed to extract safely. It could be drilled blind but I would probably do more damage that way. I'm going to have to take the inlet manifold off. So that's not ideal but it'll give me a chance to take the dizzy out, clean it out and switch it to points.
I've got a manual but one thing that's not clear is whether the oil needs to be drained first?

No need to drain the oil but you need to drain the coolant (or at least drop the level quite a bit).

I think I'll whip the bonnet off for this one.

Gasket has arrived from Burtons but they didn't have the bolts.
Got a bolt set from ebay but they are fully threaded (set screws). Is that a problem?

The ratio of bits in the car to bits on the bench is changing rapidly! Dizzy's out - looks OK. No play in the shaft but one of the advance springs is a little saggy. Most of the peripherals are off and the inlet manifold should follow suit this week.It needs a ruddy good clean.

Are there any jobs I should tackle while the engine is wide open?

Also, I'm tempted to refit the carb and double-check the flatness of the base plate. Is this sensible? The erratic tacho behaviour points to an LT problem, not an air leak, or does it?

The nuts that secure the carb are a swine to get to with my chunky spanners. Does anyone have a better alternative?

I'm enjoying getting more acquainted with the innards of the car but I'm dreading putting it back together only to find that it still misbehaves when hot...

Check the carb for flatness with a steel rule, or a piece of wet & dry on a sheet of glass. Check the inlet manifold for flatness too. crows feet spanners are best for carbs. I think one of the advance springs should be looser than the other?

OK. I've fettled everything in sight. I've even painted the vacuum advance capsule, the alternator tension bracket, and the clips that hold the distributor cap on! The inlet manifold is clean, but not sparkling, and there are lots of tiny stainless fasteners for the dizzy.

So, I couldn't put it off any longer. The broken bolt needed to be extracted from the block. Three hours, a left-handed drill bit, and some magnets from a cupboard door later, and... it's still in there. I managed to drill out the centre of the bolt leaving a modest sleeve still seized on the threads. Hopefully my trusty garage man will make it over here with an Easy Out as promised...

Well done! that's a relief :D

Personally, I would prefer to use the existing bolts (especially as they haven't been overtightened) and just replace the broken one, as I think the unthreaded portion will give more precise location of the manifold. are the replacements the correct length (I think, from memory they are in two lengths?)
