[Vwdiesel] New lister with pump and valve questions (semi long)

[Robert M. Rankin]

Hello Listers,

My name is Bob Rankin and I live near Bellingham Wa.  I had a 79 diesel
rabbit for many years and 200,000 mi.  I currently have a marinized by
Pathfinder 1.5 in my sailboat with 3,000 hours...it is the source of my
questions.

I have reviewed many of the archives, which have been very helpful, but I
still need some refining knowledge.

The engine is a 79 or 80, I think...it carries a Pathfinder # 2,524; and has
a # in the back end of the block just below the head of 682 05 625.  The
injector pump #'s end in 107L.  It is goverened to 4,000rpm.

Is this an industrial engine?  How can I tell?  What are the differences?

What is the timing setting?  I have followed the "hillbilly tuning" threads
some, but my pump has no cold start lever, can I tune without it?  I can't
test acceleration :-), and it's tough to test mileage, but can I tune by
smoke, speed and sound?  The engine seems to be down on power a bit and
smokes some at high load.  The Pump controls the engine speed up to 2,750,
and at that point the engine becomes "prop" controlled to 4,000.  I have new
injectors and timing belt.

I need to adjust the valves, but I can't use the normal tool as there is
little clearance above the motor.  Is there some other way to depress the
followers?  If the cam has to come out, can I do it with the gear on?  Does
it need to come all the way out? Do I need a new oil seal?

As and aside, my 1980 bentley list the timing as 0.83 for 77-79 cars, not
the 0.88 as in some of the archives.

Thanks so much.
Bob
