    Loss of compression on cylinder 8 is the classic sign that the head is toast. The boot is the rubber cover around the coil and plug.
  • I am on my second RX-350 by Lexus since the Lincoln Aviator. The Lexus RX-350 is one of the cheapest cars to own on the market because of the high resale value.... if you purchase and do not lease. I am even smarter now in that I purchase a CPO and save one year of depreciation. Boring car.. but safe, dependable and very very high resale.

    I was able to get Ford to pay 2/3rd the cost of the engine rebuild. It was 2K out of warranty. They should have picked up 100% of the engine rebuild because this is a known problem with the engine.

    I will not own another Ford/Lincoln Mercury product again because of the way they treated me.
  • This is what I wrote on the subject 4 years ago!

    File a claim with the NHTSB.

    The problem you are having is that cylinders 7 and 8 are fouled and you need an engine rebuild. The head/valve cover on this V8 comes in two pieces. It fouls around 50k miles and needs to be rebuilt. Ford should recall the engine and fix it gratis. There is a TSB on it. Ask a Lincoln Mercury Dealer and they know the TSB. All engines of this type, Ford puts in Ford Mustang, Navigator and Maruader fail. Mine failed at 52k miles and they covered part of it but not all of it. My 6th and last Ford btw. The dealer will quote $5500 if beyond warranty. They will pick up part of the tab if you push. Time for a class action??

    The failure rate is still relatively low - my guess is way below 10%. You only hear about the ones that fail but there are tens of thousands that never have a problem.

    Yes, it's a known problem and I would like to see Ford step up with an extended warranty since it's an engineering flaw. But from a business standpoint I understand their position.
  • Did you ever get a solution to your problem? i am having the same problem

  • I have the ability to lock and unlock my doors with the remote but I can not lock or unlock the doors using the auto lock switches on the door handles.

    Got any solutions??

    The only solution would have been a new engine. I had 11% compression loss on cylinder 8. Sold the Aviator to Carmax and bought a new car.
  • I have a 03 Aviator and I have to continuously press the brake until I hear a click before I can get it out of park. I had the switch under the pedal fixed (mechanic suggested) still does not work. Also when I’m sitting in park the truck feels like its going to cut off. Any Ideas?
  • Lots of stuff written about the problem which is the "brake actuated shifter lockup in park" on Lincoln Aviators is erroneous or more nearly total BS!
    The brake light switch on the brake pivot pivot when depressed sends 12v to a cheapo solenoid that pulls a piece of lamp chain on the drivers side of shifter connected to a plastic cam that then gets out of the way of car shifting out of park. All you do is pull the little plastic access panel as described in the owners manual off and you can see it. It can always be unlocked by pushing it forward with a screwdriver. Mine worked intermittently until I pulled the gearshift in out of 1st gear a bunch of times and lubed it took all of 10 minutes. The shifter assembly can be pulled out in half an hour or so using simple hand tools and the manual that shows how to do it costs less than $50 on ebay and their are videos as well. The cam gizmatchie can then be tied or screwed out of the way. USA shifters in San Diego rebuilds these pieces of junk and sells rebuild kit. Again right in the owners manual are instruction on how to release the gearshift with just a screwdriver!!
  • do the buttons light up when any one of them are pressed?

    Ok here is my problem 04 aviator engine runs at constant operating temp and has plenty of fluid. I have flushed the heater cores and replaced the thermostat. Heat only blows hot when engine is at rpm when at idle in driveway at stoplights etc air blows cold. Blend door seems to be operating fine I have read there is a valve in line on one of the radiator hoses but cant seem to find it anywhere. Also bought a heater control valve from auto parts store but havent installed because i cant seem to find where it is supposed to be located. Any suggestions

    Mine did the same thing, remove the engine cowl cover across the front by the radiator is metal tube with plug in it. A 1/4" drive is needed to remove the plug, mine took some heat from plumbers torch to break it free. Careful not to get to hot, there is an O ring on the plug

    My tube was empty, I filled the tube and squeezed the hoses on both sides until the bubbles stopped and tube was full. Lube up O ring and put back together

    Solved my low idle cold air problem, always hot no matter the RPM

    Hope this helps your problem

    Hey guys I just made an account to post this. My grandfather just passed and I'm planning to buy his aviator for 10,000. I don't know the year of it but it has 23,000 miles on it.

    Just wondering what things I should look out for on this vehicle that may be a sign of an issue.

    Thanks

    You will have to do a engine rebuild prior to 50K miles. This engine has a problem. Spend the grand and buy an extended warranty.
  • akirbyakirby Posts: 7,723
    If the compression in cylinder 8 is good you may be ok. Otherwise you'll need a new head (not a complete rebuild). If you can get a powertrain warranty it would be recommended if you want to keep it.

    When starting my aviator it runs just fine after starting it and shutting it off a few times I will go to start it again and nothing. Everything and I mean everything works but it won't even try to turn over. I've checked fuses fluids and everything else I can think of I was just wondering if anyone else has had this issue or if anyone could possibly shed some light on this for me.
