Made some progress on the weekend! Well into the assembly phase now, soon it'll be time to run some wires!

Very nice, will the 88 be a daily driver, what's up with series 1 engines?

Thanks!

As fa as the Series 1 engines are concernd, for sometime #1 cyl has not been contributing much to the running (pullijg the boot off the plug made no noticeable difference in the idle). Then oil started coming out of the exhaust ports of number 1 and number 2 (only the best of gaskets allow the oil to leak past them). Turns out the rings were in pieces... the goal here was to combine resources and get a running engine without having to pay silly money on a set of rings. So far so good. It's been out for a few short drives, still need to "fine tune" the timing and carb... and the water pump took to leaking!

Nice progress! What are you going to do with all of the extra horsepower the 2.5NA will give?

So... some forward progress some backward.. then forward again!

Got the heated windscreens and glow plug wired up the way I think I want them just to find that somehow I bought relays that are normally closed and energized open... So, when I flick the switch to turn on the windscreens or press the button to operate the glow plugs... relays energize open and stuff doesn't work!

New relays arrived and swapped, of course the replacement relays have different colour wiring on the connectors so I went ahead and reworked most of the added wiring so as to match colors on most places.

I have also done a pile of sorting to the OEM wiring (not to mention the 40ish years of previous owner work..) and almost have that fixed up with only a couple random wires that I have yet to figure out! So much... fun?

As some may recall, I've replaced my Series 3 breakfast with a Series 2 model so I will end up with 4 headlights up front... I have been undecided as to how to incorporate the breakfast lights, wire them with the wing headlights (4 high beam, 4 low beam controlled by single switch/dip switch) or leave the wing headlights standard and wire up the breakfast lights as auxiliary lighting on a seperate 3 position switch (off, low and high). Currently leaning towards the aux lighting route so that I can switch them off when desired but still have light up front (perhaps when doing lots of winch work at night, want light but also want to reduce the draw on the electrical system..)

Got the engine running today!!! But not without issue, horrid time bleeding the air out... then once it was running it wants to run away on me. The only way I could keep the RPM down to something not damaging was to almost completely block the air intake. The throttle bits on the injection pump seem to be working as advertised and the idle speed/throttle position stops are as low as they can go although I can not confirm that things are working as they are supposed to inside the injection pump... If I completely block the air intake is eventually stops and if I pull the wire off the fuel shut off solenoid it stops immediately. My current theory is that the injectors are not closing properly... I had them apart and replaced the nozzles followed by adjusting the pop pressure but then they sat with no fuel (just residual fuel from the pop testing) for at least two years...

Next task is to pull the injectors and find the pop testing jig to see if they hold pressure! Anyone have a better idea?

Thanks to those who stuck with me and read through my ramblings!

Adam,
If there is anything that I can do to help by you having a look at my engine, please let me know.
Any progress is good!

Thanks! Appreciate it.

Have been thinking about the problem and am moving away from my leaking injector theory. I believe leaking injectors would be a poor start/ruff idle sort of problem while I am having a max rpm only problem. Even if the injectors are leaking, the injection pump still meters a defined qty of fuel... my issue seems more like an internal failure in the injection pump... as in the mechanism that meters the fuel is stuck at wide open throttle...

Adam,
Have you had any luck with the engine?
I am curious if your engine vibrates a lot when it is running. Mine does. Not sure what 'normal' is!

Haven't looked at it much again, I have hope it will sort itself out but am not optimistic! Leaning towards the injection pump internals being stuck at wide open throttle. May end up sending a pump off for rebuild.

Having the truck on the road this spring is a realistic goal, you are more than welcome to have a look once it's sorted.

Stay tuned!

It is almost certainly the pump.  You can do a search on the CAV DPA pump for an exploded diagram. You may be able to fix it your self.

Thanks John! Yes, I am certain it is the pump but good to hear someone agree.

CAV DPA? I thought I have a CAV DPS pump... lots of info out there for the DPA which appears to be quite similar.

I have two pumps but both were stored for similar time under the same conditions so the internals are likely in similar condition. My next step will be to pull off the top cover (seems a bit of a fiddle but doable with no special tools/calibration/etc) If I can't free things up I may swap the spare and see how that goes.

All that said, given the time and money I have already spent on the engine (a rebuild) one could argue it is worth getting a pump rebuilt... a rebuilt engine with an unhealthy injection pump would be a shame. Just need to look into where that could be done! I know of one diesel IP specialist in Dartmouth (Stairs Diesel) but am uncertain of any others..

Adam,
I wonder if a tractor repair place like Green Diamond or the place in South Alton(Kings something or other...) might have a mechanic who knows these pumps.
I am watching with interest.
Good luck.

Stairs have a good reputation, they may also want to test the injectors. Could be expensive rebuilding it, maybe a specialist in England would be cheaper on an exchange unit?
