the mechanics say that it is an odd-ball problem that they never seen before, and the problem is that they are ford certified mechanics that work at the dealership. i really dont know what to do, the mechanic says that they have to tear the whole engiine apart to see whats wrong because the computer diagnostic check only told them that there is low compression on cylinder #4. they also said that the prblem could be the block, the head, the rings, or the piston. it sounds like its a pretty big problem that is going to cost alot of money to fix, so if you have any ideas on what i should do, please tell me.

I Can't believe you took it to a ford dealer and they didn't know what was wrong even before they started working on it!
I've seen it a few times myself, and I don't even work for ford.
The 2004 models with the 3.0L's have a problem with the exhaust valve seat recession causing a loss of compression.
If only they had check there TBS's they would have found the problem easily.
Hey, want to really blow there mind, Go in and give them the service bulletin and tell them what's wrong with it. You may walk out with a job offer! LOL

Yes, the mechanic is correct, it could be a whole number of things.
Yes, it is going to cost a lot of money to fix.
Yes, it is a 2004, you should be under warranty if you bought it new.
Yes, it is a 2004 and you shouldn't be having internal-motor issues anyway.
Yes, it is a Ford but that doesn't matter.
A simple way to look at compression problems is this :
If you're having low or no compression in a single cylinder it isn't getting the correct air / fuel mixture upon detonation, thereby misfiring. There are several methods to determine the root of your issue, none of which are easy or cheap to execute properly.
1. Spark - you need to make sure the #4 spark plug is gapped correctly, is in good condition, and isn't fouled. You need to make sure the plug wire is in good condition and is functioning.
2. Fuel - you need to make sure the fuel injector is clean and that it is delivering the proper amount of fuel to the cylinder.
3. A leak-down test then has to be done if those two are dismissed. You'll need to find out if your piston is sealing properly, if the valves are bent, or if a cam has a worn lobe. None of that is easy to do or fix in any respect.
The chances are you've bent a valve seal or burned a valve. A 2004 shouldn't have problems with the top-end of the motor unless excessive and unusual wear was placed on it.
NONETHELESS I can't really tell you anything. I am not being paid to daignose anything. So work with your mechanic to find the issue. The answer to your question...
What happened? There are multiple possibilities.
What should I do? Trust that your mechanic will take care of the issue and know that you will spend $1,000 or more fixing it. They may try to up-sell you on replacing parts that don't need to be. Getting ripped-off nowadays is unlikely at most shops, but still ask to see the motor, see the worn or broken parts, and ask them to explain to you in language you can understand what the problem is and what needs to be replaced. That's just my advice do whatever the hell you want.

I worked on these 3.0Ls . When they came out in 2003 they had a lot of trouble with the valve springs breaking. Every time there was a miss when running and low compression in that cylinder. If you are mechanical at all you may take the valve cover off the right side of the engine and inspect the spring yourself. If you have any further questions please E-mail me. lmgosch@yahoo.com

it could be your piston rings or burnt valve start your truck hold a dollar close to the tail pipe hold the dollar tight if it sucke up the pipe it is a burnt valve gry or light blue smoke more at start up it is your piston rings the next thing could be your cam ford is famous for wiping a cam lobe you will need to remove your valve cover to check this do not inject air into this motor you will bloww out your seals you must have the proper tools to let the air in slowly any of these can be fixed without tearing the motor apart except for the piston rings you will need to tear the motor apart for that

Get an old school mechanic to look at it,,,,most places you go to now have mechanics who where trained to use the scope and not the eyes and ears,,,,,it may be a real simple problem like,,weak valve spring,,or loose rocker arm,,,both of these would cause the problem,,,but i would say get an old school mechanic to have a look,,,go to a local high performance shop,,thats where these guys usualy work.

Have them remove #4 spark plug and place a hose in the hole that is connected to compressed air (know as a leak down test)Make sure both valves are closed (might have to remove valve cover and loosen rockers) and inject air into the cylinder. If air comes out the tail pipe you have a bad ex. valve. if it comes out of the intake you have a bad intake valve. If air comes out of the crankcase you have bad rings

These guys work at a dealership???? I agree with old school....Compression test are ok but what about a leak down test? Sounds like they need an experienced heavy line tech...lol

Is your truck blowing any kind of smoke? Is the spark plug from #4 black and gummed up? If the smoke is dark black, then it's a carbon problem. you may get away with just engine cleaner. If it's blue smoke, it's the rings, and if its white smoke, it's the block.
2004 and warranty is expired? That sucks too.

They should have done a compression test on the cylinder not jest go with what the com. diag. test said I would get a second opinion
