Thank you all for the info. Chain
inspection and specs are not
covered by the service CD. Are
there specs or is any problem
obvious due to slack in the chain
beyond the tensioner's reach?

I inspected the hose and sensor on
the intake and all appear in good
shape. I did find diesel fuel
(not oil) leaking from the
inspection plate on the bottom of
the fuel injection pump. Could
this be related?

Are there test procedures buried in
the CD regarding the transducers
and solenoid?
