    I sold my 2006 LS and bought a 2007 towncar executive L. Super high miles on it 455K is there anything I should be concerned about ? Runs and drives fine but engine sound makes me think I have a exhaust manifold leak.thx

    Paid $1800 for it sigh...

    Timing chain tensioners
    Inspect main bearings
    The coolant hose in the valley
    If the car is nice just buy a spare low mile motor.

    well its at 458500 now runs okay except for charge light still coming on off. I changed the harness seems like pulling the harness off the connector and back on fixes alleviates it for a little bit. How can I tell if its the original engine? I see it has the fins on the valve covers and I thought 2007 up were smooth? Is it common to get over 500 thousand miles on the original engine. No cel lights or smoking but should I bee concerned?
