[C38] bad injector on Universal 5424

You can probably replace the injectors yourself.  You can download the 5424

Subject: [C38] bad injector on Universal 5424

 

First, wanted to thank all of you who responded to my last question about
heat exchangers (all very helpful - many thanks!)  However, once that got
fixed, new issues presented themselves (naturally).  When I turn the engine
on, there is lots of grey smoke from exhaust (which has been occuring) AND
smoke actually emitting from the center injector (noticeable stream coming
directly from the housing holding the injector - this is new).  If the
injector were bad/dirty it would certainly explain both problems.  The
problem is, I have never removed injectors before and am unsure how to
proceed.  Some sources seem to say, just remove them and get them cleaned
(or rebuilt if they need to be) - however in Nigel Calder's book, he is
adamant about not touching injectors unless its the absolute last resort -
and to get a diesel mechanic to address it.  My question is:  

 

-has anyone else had similar problems of smokey injectors?

-what would likely cause this to happen?

-is this a direct sign of need of replacement or is cleaning possible?

-should all 3 injectors be treated equally or is it ok to just remove and
clean the noticeably faulty one?

-is it time to call a mechanic, or can I safely proceed (without special
tools) and not cause damage

 

Any information/help would be greatly appreciated 

 

Many many thanks,

Jon Whitney
