I will know more about the condition of the motor monday or tuesday. A friend of my father proposed to help me as he has to sell his 740, but it's gasoline powered. Gasoline is 40% more expensive than gasoil here, and all the redblocks look to be prone to high fuel consumption. with my 240, cruising at 90/ 100 km/H is really good for fuel economy. I couldnt tell exactly what was the MPG but it was not shameful.

At least you are in france buddy. I have seen all the gates coolant hoses on ebay reduced as old stock on ebay UK. This is a harsh reminder for me to fix our temp gauge too. I check my water and oil every time i drive the car at the moment but without instruments, failures take longer to spot.

Hope she is healthy and there no warping, I have spoken to a man recently who has a d24 cylinder head for sale and a forum member has just acquired a car for spares i know. Im sure one way or another lessons can be learned and well get you going again if you willing to do what it takes.

Remember this engine is a special beast and needs a mechanic who knows how to work on it properly.

hahaha , yes , France still is one of the best countries to get a good D24.

You re 100% right, lessons can be learned from every situation.

About having a good mechanic working on the car : the guy who's working at the garage where the car currenty sit told me one minute ago he quit the idea of doing anything on my poor volvo.

He was about to start the car when he noticed smoke getting out of the hood.
doesn't want to see his garage set on fire he said, which I can understand. We're in the middle of august and he has something else to do than trying to help out a guy with is junk car.

Now, I dont want to start an arson. What happened? You know my harness is in very poor condition. Did the steam corrode the wires? What can I do to avoid a fire, clean all the wire, disconnect everything apart from the starter and the pump solenoid?

This is getting complicated

But I have to run the HG test....

Not a good sign...
So he just left it smolder and didn't disconnect the battery?

Not enough info provided to even make a guess, sorry.

You will have to investigate further, and if you encounter shorted wiring, then yes you will have to rewire.

Don't forget the glowplugs.

yes sorry for the lack of infos...the guy did not tell me more, he was nervous and unwilling to investigate further. The insurance obliges him to do a diagnosis and he know I will not pay for high cost repairs. So i dont know if the battery was smoking, or the alternator or something else.

he obviously disconnected the battery when he noticed the smoke. I 'll take some wire with me tomorrow and will tell you more about the troubleshooting.

So the red wire of the harness that runs inside the car had burned. I removed alternator wirings and started the car. It still has the same sound it used to have since I bought the car, which is quite melodious. But 10 second later, In the area of cylinder six, water started to drip out of the head. Not just a little drop, it was flowing. Near cylinder 4, the HG protrudes from the head! I am going to remove the head, and will check for further damages.

Are you saying you already know how to avoid breaking the bolts when attempting to unscrew them or is that what you are asking advice for?
