Whats Up, Newb Here.
Hey, my names Andy and I just got my first diesel rig the other week, a 97 cummins. Ive always wanted a truck like this and now I can start playing with it.
Tho Im not new to the automotive world, diesels are still not my best area, still a lot for me to learn. Most of my back ground is with toyota rock crawlers, mazda RX7s, and rotary motors.
Ill tell ya right now this is far different to drive than my 7, torque is nice to have, but I have to keep telling myself in the corners that Im in a truck and not a sports car,

Welcome to DB! And yes, they don't drive like a sports car, but more like a tank!!!
Hey, I saw your question, and I do believe rotaries have some thermal expansion. Im not sure the exact reasoning for this but I assume its due to the unconventional layout of the boxer and rotary blocks and they rely more on oil for cooling, as well as their cranks not being in the oil pan causing the oil levels to rise during operation maybe.
I do know that the reading on the rotaries changes during operation because the rotors are cooled by oil and at higher rpms the oil is subject to turbulent forces and starts to foam up and expand. Synthetic oils tend to curb this problem and might do the same in a boxer motor.

No problem, thats just my take on the reasons, not sure if its 100% right or not. Let me know if you find anything else out, i would like to know if im wrong about something.
