Oh boy! My 2003 Aviator has the check engine light on and the code is for catalytic converter. I've replaced all the coils multiple times. Hasn't been inspected in a while because of the check engine light. Worried about having to replace the catalytic converter and what it will cost. Also live in North Dallas. 2003 Kitty Hawk w/ 111,000 miles. Car is beautiful and comfy but totally unreliable, had the rear window problem, cd player doesn't work and coil problems like most of you. WILL NEVER BUY A FORD OR LINCOLN MERCURY AGAIN!

TO BOSTON CIGAR: First, thanks for the very informative reply. You have saved me time and a lot of emotional grief. I was really beating myself up about agreeing to the recommended coil replacements, fuel system cleaning, etc. that were done prior to this "bombshell" diagnosis.
Park Cities Ford in Dallas, TX, found "compression loss on bank 2, cylinder 8 has 11% loss." They did not recommend the engine rebuild with the high mileage I have.
Sounds like I'm in the market for a new car. What kind of Lexus do you own? I was thinking about a Toyota Four Runner, too.
Thanks you again!
#958 of 980 Need Opinions Regarding Next Step for my 2004 Aviator

This is GINNY'S MOM again (ref msg #952 or 955)
Before I venture out into the auto sales world, I thought I'd double and triple check that I've checked out every possible solution. Before a major surgery a second opinion should always be sought. So, you all are my second opinion...
Below is the dealership's diagnosis on my 2004 Aviator with 116,200 miles. It has new coils, plugs, and had a fuel system flush.
"Customer states check engine light is on
Cylinder 8 losing compression.
Verify concern. Time for EEC Diagnosis
PERFORM KOEO/KOER SELF TEST AND FOUND DTC PO0308 AND P0316.
Time to perform power balance and verify misfire. TIME TO PERFORM RELATIVE
COMPRESSION TEST AND FOUND COMPRESSION LOSS ON BANK 2,
CYLINDER 8 HAS 11% LOSS, CUSTOMER DECLINED REPAIR."
He said the computerized compression test tests the injectors, spark plugs, and coils. Then they did a manual compression test to confirm the cylinder 8 compression loss.

Did you have any luck finding out what your problem was, my 2004 is doing the very same thing. Ford Dealer is clueless

I bought my Aviator new in '04. Over the years I've come to this site for guidance with various issues that came up...it has been most helpful...thanks to everyone.
The Aviator seems to take a real whipping on this site and I have no doubt that most of it is deserved. My Aviator now has 171K miles on it and I drive it everyday. I've had the usuall minor issues that come with every vehicle, but have not had one problem that even approaches the things I see on this site. I guess all Aviators are not made equally.

1) What's a "boot?"
2) Did you see my most recent post regarding 11% loss on Cylinder 8?
Would like your feedback. Thanks

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.
