    A-circuit (negative) vs. B-circuit (positive) alternator voltage regulator

    In the Bosch IF/IR alternator world, most regulators are of the A-circuit type, meaning they are regulating on the negative side of the rotor coil. Is there any disadvantage to changing to a B-circuit type regulator designed for the same alternator family?

    0w-30 VW 503.00 506.01 in gasoline engines - consumption, leaks?

    Aside from not being the most optimal choice in many or most VW diesel applications, certain VW Long Life 2 oils continue to look like reasonable PAO-based "high ZDDP" ACEA A5 options for gasoline engines. Is there anybody having negative first hand experiences in terms of increased oil...

    DCA4 and other additives really that troublesome? Drop out, deposits, yellow metal and solder corrosion...?

    While some OEMs are moving “back” to silicate or phosphate containing coolants, some OEMs never moved away from incorporating inorganic inhibitors into their specifications or preferred coolants. Overall, it seems that the advantages of inorganic inhibitors outweighs their disadvantages as long...

    Adding a tach, speed or "W" terminal on Bosch 1-wire alternators

    Some of these Bosch "1-wire" IF alternators with "multi function regulators" (MFR) have got a dedicated tach or "W" connector sticking out from the rectifier plate. Most however do not. I am wondering if there is a way of adding one without too much hacking and soldering. If you look at the...

    Cummins oil cooler - brazed or soldered? - what materials??

    Does anybody know how a Cummins 3.9 or 5.9 OEM oil cooler is being held together and what materials are involved? Are the plates and oil passages made of copper or brass, and are they brazed or merely just soldered together with something like 70/30 solder? I would like to know as I am...

    RAVENOL VMO SAE 5W-40 Group 4 PAO?

    Have your lawyer contact them! What kind of punishment are they facing for making such "mistake"? I think these guys and others are getting away with it because nobody cares and major companies like BP/Castrol, Mobil, Shell etc. don't bother because they have left the vollsynthetisches motor...

    2001 Dodge 2500, 388k miles, 36k OCI on RT6

    Thanks, it is very interesting for me to hear about that type of business. Your 6B definitely does some work if you are burning like 6 gal./hour. Please keep us updated.

    2001 Dodge 2500, 388k miles, 36k OCI on RT6

    You've got enough data to see a trend towards higher soot levels. Could it be time for new injector nozzles? Overall, everything looks more or less consistent and probably not too bad for a truck that actually does some work. To get an idea of how hard this engine is run, what is the rated HP...

    2014 Cummins ISL9/ 424hrs / Delo 5W40

    Thanks for sharing this report. I do not understand how a lot of serious stuff gets so little attention on this forum. Interesting how "much" Fe was carried over from the previous OCI. Aside from the Cu leaching issue (or non-issue), this report looks much better and cleaner than others you have...
