    modern diesel for overlanding in developing countries - post your solutions

    Yes. If the external emission system (exhaust components beyond turbo) are deleted (temporarily if one wishes), AND if proper lube oil is then used, the high sulfur (rare these days: Bolivia, Peru, Venezuela, Egypt, Iraq/Iran/Syria and maybe a handful of other countries) fuel actually lubricates...

    modern diesel for overlanding in developing countries - post your solutions

    The S (sulfur) oxidizes to SO2 and SO3 in the combustion chamber. These compounds are potent electron acceptors (acid precursors). The latter in particular forms sulfuric acid when it encounters a water molecule, which is abundant in the combustion chamber since most of the the H atoms fo to...

    modern diesel for overlanding in developing countries - post your solutions

    And the remainder (in a deleted engine) don’t apply IF using a high SAPS oil: high ash, high TBN, a la ACEA E4/MB228.5 specification. I can explain further in all the detail you require if you wish.

    For Sale WEBASTO AIR TOP EVO 40 Diesel heater $1200

    Too bad. If you didn’t buy the high altitude version, I know a very analog workaround to adjust any Webasto for altitude. Or any other diesel heater.

    MB Oil Spec OM366 LA, Fully Synthetic?

    I have extensively researched this. To the point of having multiple textbooks about the subject. With the OM366LA, the best oil would be 228.5, followed by 228.3. You do NOT need to use low SAPS 228.31/51, and it’s actually inferior when using higher sulfur fuels. One can still easily source...

    Roof Racks/Branch Guard on Total Composite Box?

    This is what Unicat added to my roof before trip to Africa. And it’s a good thing they did, there’s a 72km totally overgrown truck in Central Kalahari Game Reserve from Xade Entrance to Piper Pan that would have removed solar panels. They seem to be L pieces that are mounted flush to the roof...

    Best Expedition Rig?

    Does it need to be registerable in a US state? How old are you? And what’s your budget? And re Unimogs: it’s true that they absolutely cannot and should not be driven at 70-85mph on interstate highways. Which are pretty unique to USA. But the main issue with driving them long distance is the...

    Hierarchy of hard sided campers that handle the snow/winter?

    The relatively standard 60mm thick wallboard material that Unicat uses (3mm fiberglass outside, 2mm inside, 55mm solid urethane foam in between) is 0.44w/sq m-deg C insulation rating. For those that are unwilling to do the simple conversion themselves, that’s R12.9. I think TC uses similar...

    Diesel Coolant heater sizing question

    Unicat told me that an oversized heater leads to more rapid soot/carbon buildup in the combustion chamber, which can cause premature malfunction (at exactly the wrong time of course), necessitating a rebuild or even replacement. Because it spends too much time at the lowest heat output; OTOH...

    New 70 series

    Arc tan (.985/1.3) ~= 37 degrees Your “assumption” that ρ(h), density function of entire vehicle with respect to height off the ground, is a constant is (to be kind and diplomatic) the most ridiculous engineering assumption I’ve seen in a very long time.

    New 70 series

    Your “physics” calculations fail to account for motor, drivetrain etc being much lower than half the height; frame, fuel tanks; winches; water tanks in camper, batteries all are at bottom of camper. Or lower. So, the COG is ~1.3m high, and the track is 1.97m wide. Therefore, the tip over angle...

    New 70 series

    Mine is 11’8.5”, not 20’ tall. Shorter than a class C with enormous AC on top, they usually have at least 2, along with 1-200ah batteries which makes it useless off grid. In 18 years I’ve had to detour exactly twice due to height in 114k miles traveling through NA, Australia, southern África and...

    New 70 series

    The H55 went away many years ago. Yes, the engine options now are: 4.5L V8 turbo diesel, the new 2.8; and I’m not sure whether the 4.2L petrol L6 has been replaced by a 4.5L V8 or not. I asked Kai Gorn if he thought the 6 speed automatic had a low enough 1st gear, he answered in the affirmative...
