Been busy underneath the car today, plenty of dust, plenty of light ferrous oxide dusting but apart from a tiny hole in the panel by the spare wheel well, no rust penetration or even surface encrustation. This is good.
Not so good, Tony2 came to get the compressor wired up (straightforward - no it doesn't exceed 13A on startup), running (easy - apart from an immense cloud of dust) but leaking. The rubber gasket in the compressor control module has split, so his partner from of old in the scrapyard is coming round tomorrow to have a look (he maintained their large compressor) and see what can be sorted, including a health check on the tank. It should be relatively straightforward to replace the unit, but as my walnut shells have arrived I wanted to do some wheel blasting!

Further to post # 528 another addition to the D jetronic info. This is a particularly informative thread [ piccies] on the D- Jetronic system. Very useful if you want to check out the injection trigger contacts in the dizzy for example. It deals with a R107 V8 motor which has 4 blocks of 2 injectors each and thus has 4 injector triggers/breakers in the base of the distributor unlike the 6 cylinder which has 2 blocks of 3 injectors so only needs 2 trigger/breaker contacts.
