Just back from Ford Lincoln dealer, they advise my 2004 Lincoln V8 LS airconditoner needs a new control valve. How would I install it?

engine size is immaterial when it comes to steering
what matters is body length, mounting positions and methods, tie rod lengths , position of pinion , method f attaching steering shaft
best if you go to a wreckers and view both steering assemblies side by side to check any differences
or you can pull both out and interchange or you can go to a dealer spares and see if the boxes have the same part numbers
or you can ring a steering specialist shop and ask if there is any differences

The 3.9 L V8 Lincoln LS does not have a PCV valve. There is a tube on the drivers side of the engine that goes from the valve cover/crank case to the air intake and this is what performs the crankcase ventilation. There is no valve to change

For the Lincoln LS V8, there is a flexable tube on the drivers side of the engine that runs from the valve cover/crankcase to the air intake tube. There isnt a PCV valve for this engine, it is just a tube for ventilation.

Thermostat has nothing to do with the heat

You have a coolant control valve down low under
the a/c drier on the passenger side, bolted to the
radiator shroud

I have that car,very complicated vehicle,one of the
most high tech ford has every made

Beside that valve there are several other possiblities,
mostly all electronic

Need the experience & all the diagnostic manuals or
I hate to say it,but maybe a dealer,not many shops will
work on a ford or an LS

The V8 LS does have a history of timing chain tensioners bleeding down and causing a rattle as you describe. Make sure the oil filter you are using has a anti drain back valve. New tensioners are very labor intensive to install. Lincoln has no recalls for this problem hopefully you have some extended warranty to help with the cost of this repair.

You have COP Ignition Coils Misfiring

They are bad enough to spike the PCM
and come back on the TPS Sensor and set
the 2107 & 2110 TACM Codes
(Throttle Actuator Control Motor)

You should have about 5 more codes

The lincoln Ls doesn't use coil D,that is another ford product

Codes for COP Ignition Coils---PO301,302,303,304,305,306,307,308
The last # is the cylinder

V8 Cylinders-- 1234 pass side,front to back
5678 driver side

V6- 123
front 456

The oil leak will only cause a COP Coil Misfire---IF,the valve cover O'Ring is leaking oil,onto the spark plug.
If you have a PO304 Code with the check engine MIL Light on,then replace the COP Coil on #4.

Please DO NOT GO TO A DEALER. It is a WASTE OF MONEY

A 12 year old could change a coil, on your LS
All you need is a 7mm socket and wrench,for the coil cover and the one coil screw.
I just did one on my 2004 LS V8 in Feb. It was $59.00 at the local auto parts store
I don't dislike dealers,there is just no reason to go there ,except to buy parts,and only when the parts are dealer only.
Any repair shop can work on any vehicle.
If you ever have issues and you will have lots,I have all the shop manuals and wiring diagrams and Emission Diagnostic manual

I own the same vehicle and have all the manuals. Give me all the codes the dealer got and all they did since new, in detail. Stop with the dealer. You go to a dealer for 2 reasons only. To buy the vehicle and warrantee work ONLY,unless you have deep pockets.

Did you check fuel pressure? Fuel filter fairly new? Air filter clean and all duct work tight? Battery voltage good when engine is running? Check Throttle Position Sensor for codes and values. Also Ignition coils go bad on these ,as often as you change your socks. TPS is avail on line and auto parts store. You do not have to go to dealer or change entire throttle body, just the sensor,if bad.


You will need a new TPS Sensor,Egr Valve, Ignition Coil or two and a Transmission Solenoid Pack,pretty soon. I have a 2004 V8 L/S. Tough car to troubleshoot and a never ending saga,as is most Fords.
