Hi Morten, I managed to find the old files for you. You can download them here: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.dropbox.com_s_9mg7o0py9v3lq2r_Piston-5FEngine.zip-3Fdl-3D0&d=DwIGaQ&c=76Q6Tcqc-t2x0ciWn7KFdCiqt6IQ7a_IF9uzNzd_2pA&r=GmX_32eCLYPFLJ529RohsPjjNVwo9P0jVMsrMw7PFsA&m=LTZbEdmEMzYynO3iuXFJKimc5bteaetRLb2PWE9Bwos&s=Z-K73pnT1O-0nNI8OpQCCK7xpEw0SMfudrpmWL39Vw8&e=

I have a V engine, so I also need to tilt the cylinders in two directions without breaking stuff. Thanks for the pointer though - I had originally thought it could be done with constraints and found that I will need expressions too. I just saw a Maya tutorial where there is a two way constraint to make it work. Softimage will not allow that warning me of a cycle, but I introduced an intermediate null and now it works, with only a simple y-position expression and no trigonometry. Next I will have to see if it can be parented and rotated.
