So according to folks on J-body.org, the 2.2L OHV is the roughest running, cruddiest sounding 4 cylinder in the world. I dunno what they are doing wrong then. Because mine, with 129k miles runs as smooth as the 4.6L Modular in the expy, if not more so. It sounds better than most 4 bangers. It isn't whiny, it has a deeper tone. Apparently it has no balance shafts.... Still very smooth. Leaps and bounds smoother than the 2.5L OHV Inline 4 in the Jeep. Maybe it has something to do with me running PP 5W-30? I think so maybe. Lots of them over there like Mobil 1.
