If you can reach in and with one arm, grab the top of the engine and give it a good shake, and the k341aqs moves around rather easily,.. then ask of a lower price, or pass it and move on to what other members have suggested. The fear here is a bad oil pan, and possibility of wallowed out iso mount holes in the engine cradle. That's just the start,....
Hopefully this 1650 is pretty good all around, and has a price to your liking!
