Need to do some reading and track down what bits I need. Don't think there's much aside from the gasket, similar for the manifolds and distributor oil seal (already have the cam cover gasket in stock). It's a big old head, and being a crossflow layout it will definitely be a manifold off job. Not like the Skoda where the whole lot weighed in at about 20kg including the carb!
She's on 133-and-a-bit K miles and I don't think the head has ever been off. Usually seems to be about 100K they last unless there's a premature failure, and this has been weeping oil from the back (pulley end - remember the engine is backwards) end of the head ever since I got the car in 2012. So it's not entirely unexpected.
Be a bit of time before I get back to that beyond a quick blast tomorrow with the expansion cap off to make sure all the water is blown out of whichever cylinder it is so things don't rust.
Been poking around that computer a bit, and have rediscovered something I'd forgotten. Military spec equipment is often (but not always... I've worked on an Alvis Stalwart...) a joy to work on. If you have a manual telling you what order the 3784 pieces are meant to come apart in, and if you have the tools the designer had in mind. If however you have no data save for your own intuition, and in terms of tools just whatever happens to be on the bench... it's often a complete pig! The one tool I was wishing for this evening was a small Philips screwdriver - but a really long one as it had to reach a screw buried behind about a root's worth of other components. I *think* having now got that screw out, once I release the nuts holding the power connector onto the case that I should be able to get the chassis out. In theory. We'll see if that plays out as planned...
In other news, with a fresh set of batteries I can confirm that the Megger works just fine, including the 500V range. That will be handy for working on the valve stuff as often a normal DMM won't show the results of leaky caps - what appears as open circuit to it can quite often turn into an alarmingly low impedance in reality once a decent voltage is applied. Haven't had a chance to look at anything else yet.
Nearly forgot to mention that having had a bit of gift money left on Amazon that I picked up a little heads up display for the 107. It plugs into the OBD port and provides all the usual sort of data that you'd expect on the dash of most cars these days - most notably though it means that I now have a temperature gauge! The lack of that instrument was something that I found downright unnerving when driving it.
The speedometer readout on it ties in with the reading from my sat nav to within 1mph, whereas the speedo itself over estimates quite a bit.
