Heres what a Banjo
looks like. Anneal the copper washes, your gas ring should be up to it.
Hoohay said “I think the fact that No4 injector did not spurt out fuel like the others, it is fualty.”
So did you test the injectors by pulling them out and reassembly on to HP pipe and cranking! Err One at a time or all of em?
You are even rougher than I. and a unwise, injectors also stop hot gases getting out, hot gases can erode your engine block.
If you did that, well have a go at fixing it.
Injectors are another precise piece of gear
, If fuel didn’t come out the FI Nozzle, the nozzle holes are blocked, or its associated Fuel pump
has a problem. You could try getting Nozzle cleaning
wires from CIG the type used for cleaning
gas cutting gear
. I’m a little uncomfortable about cleaning from outside, but you already proved you are rough! Better than pulling injector apart without the right gear.
Anyway one faulty injector is not causing your problem, could be you are being distracted.
FYI the priming pump should have a lever for priming purposes, but a lot of old salts can’t be bothered cose it takes long time. I had a V16 once that I’m sure only fired on 1 or 2 cylinders after Bosch fuel pump
O/haul, but the increased revs had that engine purring 10 seconds later. Really it shouldn’t take much to prime your system.
That thing under the Perkins
decal, that’s the fuel pump block, Possibly where the governor is. (Note: If you have a 4 cylinder, then you have 4 fuel pumps in that block). It would be nice to know, which side of the Governor we have (my alleged) sticking problem.
A little worried we are creating more problems.
If you pulled injector out, the injector pocket and injector have to be clean and gas tight. It could be metal to metal or a special washer that may need to be replaced or relapped. Careful we could be talking grinding paste and mandrels if you get it wrong.
That S/D solenoid may need to be investigated for proper function, does it look easy to disconnect.
Disclaimer:My logic comes from a 1/2 life time of repair in remote
places, these days it may be better to spend the money
. But I also think its important to self learn, A technician thou clever can solve the problem but only by changing out everything until the problem is solved
. I want the OP to be in a position where the diagnoses is accurate and the list of changed out parts
is very short.
