Hi, folks! Wife and I are on the verge of buying an
'00 Dodge 2500 diesel to run on biodiesel. My main
concern, given my history, is with fuel injector
return lines. On examining the engine, I noted that
the injectors appear to be inside the engine block, or
at least not have return lines. Which of these is in
fact the case? If the injectors are inside the block,
do they have return lines, and if so, are they made of
rubber, metal, or what? If made of non-Viton rubber,
how difficult is it to get at them to replace them?
Are there any other biodiesel-related issues
particular to Cummins diesels of this era of which we
should be aware?
Also, the engine was louder than we expected (and
we've heard other diesels, including other diesel
pick-ups which we've test driven, but all these were
Fords) but otherwise seemed to run smoothly; could
that be cause for concern?
Finally, about when do these vehicles need the timing
belt replaced, and about how expensive a service is
that (parts and labor)?
Sorry to bother you, and thanks!
DG
