[Vwdiesel] Diesel Hagar the third person ??? .

[Tyler "Casioqv" Backman]

My 6.2 has never had any injector pump problems or leaks after 240k
miles, and I am sure that it will never have any. It has never had any
lubrication additive, and runs on #2 diesel, but will soon be running on
Dual fuel Biodiesel/Vegoil. I often hear of problems with the Bosch
injectors going out every couple hundred thousand miles, but not the
injector pumps. I suspect that your friend's injector pump problems were
likely due to using fuel with poor lubrication properties, or something
such as water in the fuel, but not the result of a poor quality pump. My
point is not that the 6.2 is better than some other motor, but that it
isn't bad, and can provide a long trouble free service life. Almost
every diesel motor in existence (especially the VW Diesel) has a bad
reputation in many circles, and I think it is primairly because of
problems that people have because they do not understand about, or how
to take care of diesel engines in general. Even the 5.7 can last over
500k miles if well maintained. I did note that I would rather have a
Cummins motor, but they are more expensive. I am also a big fan of the
IH motor, but do not like many of the newer truck motors, because many
of them use wet liners (worrying about anti-cavitation additives can be
annoying), use electric injection (has many advantages, but I like to
keep driving when I am in mexico 300 miles from the closest town, and I
have my alternator go out), direct injection (does not work well with
varying viscosities of fuel such as vegoil, which change the spray
pattern, and can cause oil to wash of cylinders, or improper
combustion), and they cost a lot more than a 20 year old 6.2. I
understand that these newer motors (Powerstroke or Duramax) are possibly
a better option for many people. My truck with Banks Turbo kit and
Blackstone (Volvo) Intercooler puts out approx. 250hp and 450 ft*lb of
torque, with a total investment of under $3000. A 6.9 puts out approx.
175hp and 365 ft*lb of torque stock, while a 1992 cummins puts out
approx. 160hp and 400 ft*lb of torque stock. Basically, any of these 3
motors is more powerful than the other 3 if turbocharged (and especially
if intercooled), but all have similar power outputs from the factory.
The 6.9 will likely produce the most peak horsepower, but the Cummins
has a much better torque curve, and can get a much bigger trailer
started at low rpms (the same motor is used in many commercial trucks).
When I get some money, I would like to get a IH Traveler Turbo Diesel.
Also, note that I do not race my 6.2, but tow trailers with it. A heavy
duty diesel engine is not designed for running at high rpms. If you want
to race, I will race your "ATS turbo'd 6.9" with my 300 horsepower 1800
pound Porsche 914 when I get it done.
