    How critical is it that a 82 diesel engine have the
   oil squirter system. I have a very good 82 that
   requires a new engine. I have a factory rebuilt 1.5
   that I am considering installing. Without the
   squirters, how much of a detriment will there be on a
   new engine?

    Any advise and tips would be appreciated.

Driving style and condition of the rest of the drivetrain
will affect the load and wear on the engine. A good condition drivetrain
(e.g. exact wheel alignment, good bearings and CV's etc) with
the 5.43 final drive ratio can do a top speed of about 65Mph / 100-110km/h
(+-10% or so). At that road speed the engine is turning 4000rpm
and developing nearly its rated 50HP
(see graphs at www.cs.yale.edu/homes/jag/vw/engine/tdiswap/tdiswap.html)

However, if you drive just a little bit slower, 55Mph / 90km/h, the
engine load decreases dramatically to about 25-30HP.

To cope with the sustained high loads at top speed VW designers added
some improvements to the vanagon version of the VW engine, hence
ideally it should be replaced with a vanagon block, or a TD block.

However, for the careful driver that is satisfied by a sustained
highway speed of 55Mph / 90km/h, a standard automobile type (e.g.
jetta, golf, rabbit) block will do. Using this block won't prevent you
from occasionally fully loading the engine (while e.g. passing farm
tractors and mopeds...;-), but it is advisible to avoid suatained full
load for long periods.

Anoter solution which many vanagon owners have been pleased with
is to swap the original 1.6l block for the more recent 1.9l NA, TD
or TDI. There is much information on this swap in the Vanagon
archives (gerry.vanagon.com) and I have a few pictures on:
