Question about 2005 Ford F 350 Super Duty

Open Question

We have a 2005 F-350 6.0 Power stroke engine, and

We have a 2005 F-350 6.0 Power stroke engine and it has been having problems. When ever the engine starts to warm up from the exhaust we get black smoke Then the engine starts to hesitate cutting power to the throttle temporarily. It then release white smoke and brings the engine back to normal. Any ideas on what might be causing this? Thanks. - Aziz Kurtoglu

Some of these engines have a place to drain water out of the fuel system.. Some fords actually have a stick under the hood that you push or pull That opens a valve on a water collection bowl. It's not labeled usually. It might state where it is in the owners manual under fuel water drainage or something similar.. if that bowl is full it will cause hesitation... If it gets over full it will cause runability problems. Another possibility since you said it's black smoke is one of your injectors is sticking at low rpms and squirting raw fuel into the cylinder till the rpms get up enough to burn that fuel off completely then then the injector works a little better.... Do you notice any missing... Feel something under the hood like the air cleaner housing and make sure the vibration is constant and doesn't have a small sudden shake and the n smoothe... And then a small sudden shake again.
If it does have this shake you can trouble shoot which injectors by with the engine running loosening an injector line and seeing if the engine runs worse or not.. If it runs worse tighten it up and move to the next line till you unscrew one and feel and hear no difference... When you find that one that's the injector with the problem.

Rotax 503 i do not trust anymore scarry stuff!when it stops close to ground

Be good if you asked your question...

Rotax seem to have a decent reputation but the 2-stroke engine has a number of disadvantages compared with the 4-stroke though the major advantage of the 2-stroke, the lighter weight and superior power to weight ratio capability of the 2-stroke makes that type of engine more desirable for a number of applications.

Most of the disadvantages can be reduced by careful building to very fine tolerances, what is know as "blueprinted". That goes some way to explain why those engines approved for use in aircraft cost more than double of those used on the ground.

While a blueprinted engine that is better balanced is less likely to suffer serious mechanical failure due to sustained high revolutions in the way an earthbound engine probably would, it doesn't make them immune from such things as whiskering spark plugs, spark plug oiling, dirty fuel, ignition failure or carburettor icing.

The aero engine is a superior build and it needs superior maintenance and routine attention, carried out as if a surgeon operating on a person just as a mechanic of a formula 1 racecar would but even then problems won't be eliminated - merely shift the odds to more favourable...

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?

Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

I have a 1994 ford escort and it's not getting eoungh power I've change the battery, sparks plugs and the alternator don't know what else to do please help

Did you check the timing? If the timing is off there will be a reduction in performance and power will be greatly reduced. If the engine is "pinging" or "knocking" under heavy acceleration, your timing is advanced, and pre ignition is occurring (that's when the spark has ignited the fuel in the combustion chamber prematurely), resulting in a knocking sound. When the piston is compressing the air/fuel mixture within the combustion chamber, the spark plug produces a spark from current it receives from contacts closing in the distributor cap. (Where all the spark plug wires are plugged into) if that spark come BEFORE the piston finishes it up stroke or compression stroke, the piston is then being slowed down from the kinetic energy produced by the exploding fuel. Thats where we loose our power. Idealy, the spark should come AFTER the piston has rotated over the top of its stroke, It has reached its limit in compression and is on its way back down then the spark should ignite the compressed fuel, thus giving the piston an additional "shove" back down to start its "Power" stroke, once its reached the bottom of the power stroke (stroke #2 of 4) it is then carried back up for the "exhaust" stroke pushing the burnt fuel out of the combustion camber and into the exhaust manifold, one it has reached the top of that stroke it begins its journey back down to start stroke number 4, the Intake stroke. Drawing in air/fuel mixture to again be pushed back upward to compress the air/fuel, and repeat the process over and over again. Now that I have thoroughly bored you to tears, Yeah, check the engine timing, if its not the timing it may be a vacuum leak.

Can an engine rev when cambelt is taken off?


To answer your question directly......NO, the engine can not rev when the cambelt is removed, it won't even start. This is virtually impossible for any 4 stroke engine.

i will explain why....... The cambelt connects your camshaft with your crankshaft, when the engine was assembled, the camshaft and crankshaft was turned on the correct alignment marks and the cambelt was fitted. These marks on the cam and crankshaft allows the 4 strokes to happen at the correct time(intake stroke,compression stroke, power stroke and exhaust stroke) If the cambelt had to be removed, there will be serious damage done to your engine, in the first place, the car will not start if the cambelt was removed. the correlation between your camshaft and crankshaft will not correspond and the pistons will hit and damage the valves.

I hope the above description will help you.

Stumbling on acceleration

You may be cruising down the wrong road with the exhaust idea but then you might be right. An exhaust restriction should also cause the engine to run hot. A faulty cat should also set some codes.
If the injectors are dirty, you may have a very lean fuel mix on one or more cylinders under acceleration, which would go away once you are not under load. And injector problems won't set any codes unless an injector stops working completely. Low fuel pressure could cause the same type of issue.

Ford 1999 4by4 7.3 power stroke diesel turn over but will not start

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

1994 jetta gl need timing marks location

Hi, the timing marks are stamped into the steel pulley and flywheel and there should be a pointer attached to the engine. Degreasing the engine with GUNK and power washing it should uncover them.

I'm pretty sure it's crucial to have the engine timed to TDC as it relates to the end of compression/beginning of power stroke, and NOT the end of exhaust stroke.

With gas engines I do the following, to determine the TDC, by removing the #1 plug and insert a long straw, while turning the motor by hand watch for the maximum height of the straw, this will give you a TDC but knowing if its on the exhaust or compression stroke can only be determined if you were watching the closure of the intake valve indicating the begining of the next power stroke. Once you have this set look for the timing marks again. if you can't find them pick up a service manual at the library or autoparts store for photos and instructions.

Explain the four stroke cycleof a three cylinder

Is this a quiz? Each cylinder contains one piston that takes four strokes to coplete a a full cycle. the intake-down,compression-up, power-down, exhaust -up.
A two stroke has up and down only . Compression and power Now, I thik you really meant the firing order. I'm not sure but Would make sense 2-3-2?
