I have a thread here where i put a 84 617 in a mazda truck ..
well now ~10K later i think my ip is giving me grief ..

cold start (20_ out) it idles at 510 ish rpm
warmed up 170deg its idling at 1100

now i know there is supposed to be a idle adjustment on the dash ...
But its shouldn't vary THAT much ...

also ,. right when it starts it lopes, coughs and misses and smokes blue

will get a pic of the IP tomarrow ....
its a funny one with a screw on the back .
vac off on the back and a manual off on the side .


is the IP going bad ?

my injectors were new 10K ago .. but i will pull them soon and test ..

2nd question .. will a 76 300D IP work ?
i have some of those ... seems like needs
1 diff fuel line routing
2 diff throttle cable setup
3 diff injector lines that i have .


thanks
cody

Can't actually answer your main question, but I'll address some asides .

1) The 300D turbo never came with an idle adjustment cable.
2) The '76 300D IP would probably work, but it would really limit your power... the turbo IP delivers more fuel than the NA IP, so reverting to the NA IP would make your engine perform more like a NA engine (~90 HP v. ~125 HP).

then it may have had a cable. it sounds like your cold running enrichment might be out of whack.

thing is it seemed to run fine 6k ago ...

if you gold down the gas and keep it at 1000 . right when its cold , it will still cough and gag ..

I have also noticed my power and mpg has dropped ..
vary hard to get it over 65 mph ....

I have played with the smoke screw ... in either direction .. seems to make no difference .

well here is the IP



I dont think its so much the IP now ..
pulled all the injectors , all were NEW monarch from ... "that other source" .....
NONE of them are POPing . they are just spraying ... no wonder it runs like crap ..

put old bosh ones back in i poped , and runs much better ... little lope right at first that still might be the IP .

The Pump in your picture is a "M" type pump. the IP sold in the North American Mkt is a "MW" type pump.

If you swap in a 617 NA IP, then you will need the fuel lines from it. I don`t know if the "M" pump Fuel lines will work.

With the MW pump you will need vacuum to shut the engine off.
I thought the M pumps used vacuum also, but looking at your picture I see a cable.

I think its running OK now ..

I am going to try returning those injectors .....

Need to take for test drive .. Should adjust valves before i decide if worth swaping pumps ..

Yes.

Sounds like your Injectors had something run through them they did not like. Have you only been using Diesel Fuel?

Blue smoke is related to Oil burning. Are you still haveing the blue smoke now that you swapped the Injectors?

Several Members have had a situation where the little O-ring in the Fuel Supply/Lift Pump was worn out and allowing Oil from the Fuel Injection Pump to be sucked in and mixed with the Fuel.
What type of Oil crankcase consumption have you been having?

Worn Valve Guides and or Valve Stem Seals can also allow for Oil to get into the Cylinders and burn.
If you remove the Manifolds I believe you will see that.

Oil making it as far as the Pre-combustion Chamber and burning there leaves the Pre-combustion Chamber Carbon shiny and wet looking.
What did the Pre-combustion Chambers look like when you had the Injectors out?

If someone local has a Compression Tester you could barrow it might be interesting to see the results.

The monarchs were advertised as being better for WVO and such so i figured they should hold up to more then bosh ones ..
But no , from the time it was running good until it wasnt it ran just diesel with nothing added .

Truck does burn a small bit of oil ... 1q per 1k miles or so .
I think that is valve seals ..

The Injectors/ washers had lots of carbon buildup on them that was dry flaking looking

I was not implying anything negative.
For Me I have had to do more repair work on My Mercedes than any Car I had previously owned.
I also had trouble trying to learn enough knowlege fast enough.

As far as I know the Monark Nozzles are not specifucally made for any alternate Fuel. The Nozzles just don't have the tiny drilled passages that the Bosch Nozzles have.
So I guess M source is thinking that they would be less likely to plugg.

The Monark Nozzles have a flat spot (facet) on one side of the Pintle that for the idle Fuel.
That is similar to the later Bosch Injectors that use the DNO SD261 Nozzles (ore is it SD216???).

The Facet is supposed to do what the drilled passages did in the Bosch Nozzles DNO SD240 and DNOSD240/.

I did not mean anything netagive.

I don't think the Monark Nozzles have been specifically designed for WVO use.
Like the Bosch DNO SD261 Nozzles used on the later Engines the Monark Nozzles have a flat spot on the side of the Pintle (a Facet). And, the idle Fuel is supposed to go through there.

The same function was done by tiny drilled passages on the older Engines. But, on My own Engine those tiny passages were plugged solid with Carbon (198K miles looked like original Injectors). I am thinking that unless periodic Diesel Purges are done those passages cannot remain clear.

So to the extent that the stock Bosch Nozzles can get plugged easier/faster with WVO use the Monarks could be better; but, that does not mean they were made for WVO use.

I think M Source is sticking its Neck out saying they were made for WVO use; if that is what they said.
It would be interesting to see what they say if you Email them with your Injector problem.
