I have not posted in here for quite some time I have a 2017 Prius prime my antifreeze or overflow was leaking. I bypassed the main system and it seem to be fine with no leaks. Long story short the antifreeze was going into the engine and I blew rod, does anyone know where to get a used Prius prime engine from that’s not 3k I have 155k on the car & commute 200 per day -
For forensics: Was the leak in the exhaust heat recovery system? The system being exhaust heat recovery system? Long story would be good: is there evidence of head gasket failure, or did coolant level just run low, engine overheated? That’s a piston arm? Can you post another pic, showing larger area? Hard to tell location/orientation.
