Thats a thought. However Vauxhall Opel of the era isnt my dept! K-jet is constant spray injection so thats a different animal, it would have to be L-jetronic with solenoid injectors and some form of Hall trigger/TCI ignition (which is more important) and use the AMP 3-pin round plugs.

I've seen a pic of whats inside the unit and there's four seprate ICs so its busy thing. For my needs, I'd have to track down something suitable that was using 6 banger using L-jetronic circa 1985. VAG were still getting into their inline 5's for everything apart from the V8 so I've got to go off br...

However, I have gone down the rabbit hole and found a samba topic (#735600, page 4, oscilloscope waveforms of fuel pump, hall sensor, injector, spar) where someone has tested the DLS and it does definitely advance the timing slightly if the engine idle rpm are pulled down by external factors. So its...

251906083A, manufactred by Telefunken (TLF) or Siemens or AEG. Marked 4-zyl. I've been thinking a bit about this box of mysteries and what it actually does in a VAG TCI application when used with a double sided advance/retard DJ type distributor, since my wbx6 has provision for one but I don't have ...

Seems like an awful lot of effort to end up with a mongrel coolant system that may or may not work properly? Remind me why you didn't just convert it to the later coolant system and be done with it? If you connect the two thermostat housings together 1. Its another long hose to let you down and more...

As for the melted injectors...obvious external damage or have they pulled them and found that the pintle shrouds have melted?
What are the circumstances of the overheating incident? Fuel system fault causing it to run very lean (pump failure, blocked filter, air leak)

£4k for a "recon" DJ will barely cover the parts and labour to build it, in fact it will have been build by someone working for not much more than the minimum living wage with zero overheads.

I've got a couple of so-so used syncro type (cast alloy) thermostat housings that you could use as a bypass manifold for small pipes, obviously you'll need to blank off the top where the thermostat housing bonnet fits and also the main coolant outlet. But it could solve a few problems in one hit. St...

Glad to see that you are still around Mr Numbers!

I spoke to Ken Newman the other day, flat 4 cam blanks in the correct grade of chill cast iron are now back in stock, following a change of supplier. I'll be getting some in ground to the 2.1 spec as well as a fast road profile for bigger capacity engines. I presume that Andy at Campershak will be d...

Got to say that 125psi compression isn't exciting, so its going to be down on power. You won't "save" a short-stroke flat 4 by flogging it at low revs, wind it up to 5k if and when you need it, I've sent a DG off the end of the tacho with no ill effects.

How heavy is the bus? Did you change down a gear or two? All VW flat fours are happiest when above 2500rpm, it's not a modern Tdi that will chug along at sub1800rpm and still make meaningful torque

I was going to say that its for a tacho. The bus is.most.likely an ex-taxi or working LKW.

Do your homework before using a helicoil type kit! Use appropriate length inserts (expressed in multiples of diamater i.e. 1D, 1.5D etc) When the coil is fitted it in this sort of situation it should be a half turn short of the total hole depth at each end, under flush for two reasons: It stops the ...

Sludge is fungus that lives off the ethanol, its commonly called "diesel bug"

You shouldn't need a hand bulb to prime the system, must have an air leak thats preventing it from priming.

I'm no td expert, do they have a lift pump?
