My 404C resto begins!

Ray Bell was at our place for three days as he fettled his Dodge camper for a long trip all the way back to Aus. Although the 404C was not ready to drive, I got this photo on Monday.

Had a few hours today so I reversed the connections on the fuel tank. Before the engine was installed a few weeks back, I connected a Pela oil pump to the fuel return line and when I did, it sucked fuel out of the tank! Not supposed to happen. I could not remember which of the connectors on the tank was supply. None of the factory manuals lists which is which.....

So today I installed the fuel lift pump, the lines and then reversed the lines at the tank.

Mounted the injector pipes. One had rusted inside again in the 2 years since it had been off, despite having WD40 inside and being capped. The other three seemed perfectly clean after spraying some fresh WD40 through. So I happened to have only one of these pipes in NOS, as it turned out, the one that was rusty inside, so I replaced it. The colour is slightly more patina-ed than the ones I had replated. Which I think is why they rusted inside in the first place.....

Accelerator cable, thermostatic injection hoses with their guide, rear intake manifold support strut, distributor.



 
Any thoughts on anti-freeze? I bought 4L of Mercedes-Benz concentrate for the 404 and posted about it on Facebook and all hell is breaking loose. Some are suggesting that the modern coolant will destroy seals (what seals? the liner rubber seals? The asbestos water pump seal? the head gasket?).

Any thoughts or recommendations on it would be appreciated, with any brands known to be good.

Cleaning out the injection tubes for the third time....they still have ample crap in them. Got some de-rusting gel that is inside overnight, and they'll be flushed and reamed tomorrow. The set that was once again on the engine still had crap in it......which you can see in the tray inside some of the rust removal gel.

Finished cleaning out the injection tubes Sunday. Orange stained acidic gel came out, as did some more chunks and then Brake-Kleen was used to blow some more liberated grey crud out. As a final step, the tubes were oiled with 0W20 to coat the inside with anti-corrosion that will remain until they're full of nice clean fuel.

This photo was taken after the hot water flush: Brake-Kleen released even more crud from this spare set of injection tubes!

Orange/yellow rusty gel coming out of the tubes after 12 hours inside.

Oil draining out of the newly cleaned tubes. 4 of these 5 will be used on the car.

Remounted again.



The spare set, once the caps holding the motor oil inside came off, look as though they need another bit of flushing/cleaning work, because unlike the set on the car now, they're draining very rusty looking oil.

I also poured 3.5 L of Lucas break in straight 30 oil into the sump tonight...
 
Surprised you've left the oil until now - not something you'd want to overlook...
