Once had an Omega 2,6 caravan and was thrilled by its smooth running and the speed. Since this engine was unfortunately no longer available I added a 2.5 V6 (Caravan). This engine is now unfortunately something else: Brummelig (but goes like this), clatters in idle mode (disappeared at slightly higher speeds) BUT: the box is a bit lame: with solid material max. 210-220 (according to Tacho) on the track is not so great. Is this with this engine, which with 170 hp nevertheless more power than the old one 2,6i is supposed to have just like that? Or does the box have any Macke???
