This is Part II of a thread I started a couple of months ago. And, I realize I am always here asking for knowledge and advice and not giving much in return - I’m just not an expert. Interested in learning, but no an expert.
Long-story short: I installed a remanufactured engine after my Jeep threw a rod. Bought the full “everything with gravy” warranty. Threw an engine light two days later that goes on and off every couple of days. Misfiring cylinder. Swapped coils, plugs, etc. Those + the injector checked out. So the mechanic ran a CO test and found a bad head gasket on the cylinder. Found excessive pressure in cooling system - bulging hoses, leaking coolant.
Engine seller not returning emails or calls. Next step on my plate is to contact credit card company and open file there. Any advice from this crowd?
