2010 Ford Expedition 5.4 3v - My mechanic (Christian Bros Automotive) just told me that he did a power balance test on my engine and it shows that cylinders 2 and 4 have very low compression. He said that it is either a cylinder leak, a cracked head, or a cracked engine block. He recommends a new engine and said it would be between $10,000 and $12,000 (parts plus 25 hrs labor). The engine has 186,000 miles and idles rough and has lack of power when accelerating. No CEL codes are being thrown. It has all new timing components, rollers/followers, new spark plugs, boots and springs, new heater and radiator hoses, upgraded oil pump, new MAF sensor, all new O2 sensors. Pretty much anything that I touched when doing the timing job was replaced with new OEM parts. I'd appreciate any thoughts on what you would do next. I don't really have the money for a new engine or to go buy another vehicle but this one is due for inspection and registration this month and won't pass in the current condition (because it shows P1000, On Board Diagnostic System Readiness Test Not Complete) which means that I would be risking getting a ticket for expired registration if I keep driving it. Thanks!
