95 F350 7.3L diesel engine. Fuel leaks at connection at top of engine. Is this a bad gasket or o-ring type problem?


Without seeing it (the leaking area) or having eyes on, that is impossible to say, but Ford is partial to "O" ring seals in the fuel system. Fuel seals are made from special materials, so get the right part.

Oil leaking out of the top,front area of the motor. Took about 2500 RPM to keep her going 10 mph.


Oh my,, It looks like HOPEFULLY the top gasket.. but the loss of power means the engine is loosing compression, suggesting that the engine block is cracked or the tapit pan gasket is broken.. Hopefully its just the seal.. I strongly suggest you get a pro to look at this and fix it for you..

but if you want to check the engine block to see if its broken,,,, take out the radiator cover and start the vehicle,, if you bubbles or the water pumping out,, you got a damaged engine block.. If not then is the seal.. you need to take the engine top off, to fix the seal,, its the one that seals the top to then engine itself.. This is one i found on youtube for a honda but the steps are basically the same..

Engine won't go over 5-10 MPH


You need to take the car to the dealer, because you need to recalibrate the electric throttle body with a TECH 2 Scanner, because the system went into a Limp mode.

Esp light comes on and stays on. Car will not accelerate - will only go about 10 mph


this happened to me a few weeks ago, although no light came on, the car is diesel engine. i was told to change the fuel filter, this was no better. i had to take out the back seat and open the fuel tank from the top (there is a lid sealed on) then change the gauze on the end of the fuel line. cost me 6 quid from toyota

Vehicle won't go over 25 mph. help!!


Hi

If you have engine management lights showing on your dash your car has gone into limp (or safety mode) and this explains your problem. In limp mode the engine is locked down as a safety measure to get you home and will not operate normally.

If this is the case the car will have to go to be scanned for error codes to identify the exact cause of the fault causing the limp mode condition.

Hope this helps. Please remember to rate my answer. Thanks.

My 02 3.8 windstar starts chugging down at redlights. i have changed the idle air control, the plenum gasket, and the egr valve


Chugging down? Do you mean your engine is almost stalling? Sounds like your fuel filter is clogging up. Change it before your fuel pump dies. A Fuel Filter's like $10 - $15.

My mx3 just had the head done and it is still blowing blue smoke once a day when i first start it... the mech that did the head said the compression was done and good and that when they opened the head...


Sounds like the excuse is a load of BS to me. If that was the case, the oil would of been burnt off during the normal test drive after they completed the head. I'm assuming you had a blown head gasket?

Blue smoke is indeed oil and if it ONLY occurs at start up then clears itself after some driving, it's the valve stem seals or valve guides (but more likely the stem seals).

They were most likely not replaced during the overhaul.

The stem seals stop oil from the upper lubrication in the head travelling down the valves into the combustion chamber and burning with the fuel.

While the engine is running, there is enough movement in the valvetrain (all the bits that move the valves) so that oil cant make it down into the combustion chamber.

However, when the engine is stopped and left for a period (ie: overnight) oil can trickle down into the combustion chamber through the seals which is why when you first start it up the next day it blows blue smoke. All that gathered oil in the combustion chamber is burning off.

The reason why they probably haven't changed the seals is simple: they make more money.

As a mechanic doing a head you have 2 options: You can either get what's called a 'Headset' which is the head gasket with all the other gaskets involved and stem seals OR you can buy the head gasket by itself and reuse the old gaskets and not replace the stem seals.

The head gasket by itself is half the price of the Headset but you can still charge the customer for the full headset....see where im going? Trust me, this kind of practise is unfortunately very common and one of the reasons I got out of the industry.

Once a car overheats due to a head gasket or any other problem, the stem seals nornally always have to be replaced because they harden due to the heat and lose their sealing power.

The solution? The head has to come off again to replace the seals and these guys probably know it so they are going into BS mode to protect themselves.

You have to insist they fix the problem because it wont go away and don't back down!

Oh, and for future reference there are only 3 kinds of smoke you can get:

Blue = Oil burning
White = Water burning (pretty normal in the morning)
Black = Fuel burning (Mixture running too rich)

Hope this helps :)
