Peace, mercy, and blessings of God be upon you. I have two Isuzu Dyna 2008 4HF1 standard engines. They only need piston rings and are guaranteed to be in good condition. You can come and see. 4HF1 engines are very clean, God willing. They only need rings and to be closed up. They don't need anything else. 4HF1. Contact number: WhatsApp calls 0597130595
