Currently drifting off the coast of Sicily!

Thanks, Nick. It was great to understand the relationship between bleeding the system and the injectors. When routinely replacing filters, do you think it is worthwhile to fill the filters with dlesel, before mounting.

Thanks, John. I think my fuel lift pump is gear driven from the main engine block. "think" with emphasis lol

Thanks, Slavko. I managed after a lot of WD40 to remove the copper fuel supply pipe from the pre-filter/water separator. There is no fuel coming from the main tank. So there is the problem. 

How do i unblock that hard copper pipe?

Is it possible to run the engine from a jerry can?

Daniel,

If the fuel tank is higher than the engine and quite full then you have gravity on your side, it makes it easy.

First turn off the fuel tank valve. 

Then clean the primary filter and replace the paper element.

Then take off the secondary filter spin on type. Replace it with a new one.

Then just above the secondary filter on the engine there will be e hex head nut with often a screw driver slot in it. Have a spanner or ratchet ready to open it.

Open the valve at the fuel tank, and open the bleed screw with the ratchet.  Gravity will make the diesel fill the primary filter and then up to the secondary filter at which point it will flow out of the open bleed screw. At first there will be frothy bubbles, then it will flow clear fuel. Close it tight. Not too tight just snug. 

At this point everything is bled up to the secondary fuel filter. On new engines you may be able to start the engine but if the engine is say 20 years old then it is better save your starting battery and crack the injectors. You will see that the hard metal fuel lines (pipes) go to the fuel pump and then to each cylinder. I think with a number 19 spanner you just open the injector nut a half turn for each one, place a rag by each one. Turn the engine over with the starter and when you see fuel spurt out of the injector line close it with the spanner. The engine will probably start on two cylinders and then three, and so on as you close the injectors.

If the fuel tank is below the engine; there will be an electric lift pump that comes on with the ignition. Do the same as above but with the ignition turned on, you will hear the clicking of the fuel pump.

I hope this helps.

If you sucked water into the engine fuel pump, then you have a problem. It will be damaged. You will need to wait for the wind and sail. More than likely need an expert.

If you get the engine running and all is well, when you get to a safe anchorage or harbour I strongly advise you to empty and clean your fuel tank. Filter the fuel and treat it.

Hello Amelians

We're en-route to Sicily. I was sleeping. I gave Anette instructions to check the engine temp constantly dial while at the helm. 

She said that she heard the engine increase in revs for two seconds then back to normal for a second and then decreased for two seconds and then it and cut out. 

We have been at sea 36 hours with engine on and off during this time. The engine seems hot but we have been running her constantly for about 12 hours.

I checked the sea strainer. It is clean. Water is coming through the sea cock. There has been low engine temp throughout the journey. 

I am guessing the impeller has gone and it overheated.

Can anybody tell me anything about this situation before i attempt to restart the engine?

Venting the fuel system can be poor in some cases. Volvo recommend to turn the engine so that the drive cam for the pump changes position. It happened to me in my pervious boat.
one way or another you have to find if you are getting any diesel from your tank. Be careful as diesel 🔥. I do not know Mango so all what I am writing is based on experience from other boats I owned.

good luck.

Thanks, Nick. It is def fuel starvation.

I have never done a filter change on this engine before today and have never done a bleed on ANY engine, before today.

 

I filled both filters and their respective baskets, to the brim, with filtered diesel, before fitting them.  (I know it is better to change one at a time with a bleed in between. However, I took the second stage filter off before i realised that the first stage water separator had been emptied by the engine before it shut down)

 

I have taken off the bleeding bolt at the place which receives the high pressure pump return fuel and I am trying to pull fuel through with the manual lever of the fuel lift pump. It just won’t come through. I have done about one hundred pumps of the lever from lever bottom position to lever top position.

 

  1. Am I attempting to bleed the engine in the correct manner?
  2. If i want to check for a blockage from the main tank to the first fuel filter/water separator, do I just remove the intake and the fuel should flow out by gravity?
  3. If there is a block could I put the intake pipe into a jerry can of diesel and the system will pull it through without the gravity of the diesel in the tank?

Thank you, guys

Daniel,

I would check for fuel starvation….sounds like you may have blocked fuel filter. Of course it could have overheated but normally there would be an alarm. The engine would also then run normally after it cooled down until it overheats again…

Good luck

Wow, Louis, thank you. So i should ask the towing boat for their line and never give them my line. Good to know.

It is a fuel line problem. I am now changing the filters and bleeding.

Thank you everybody.
Louis Trepanier
 

Just an advice in case that you don’t know; If you ask anyone to tow you for entering an anchorage or a port, don’t handle your line to the towing boat and ask them to give you their line. 
This makes a BIG difference as if you use your line, the tower can declare “salvage” which means, by the book,…claiming up to 50% of the value of your boat…Pirates are not only in Somalia- I had a very close call of this nature in a Greek Island a few years ago.

Also ask before any towing is done that they declare their condition for assistance.
Good luck with the fuel issue.

If the heat sensor is working, the engine should stop and show a high temp signal on the display and-or- an alarm should sound if there is no fault display on your system.

If the impeller was the problem and the alarm din’t go on, have the sensor tested at next port. In the mean time, use the engine only for short period and at low rev. Because if the safety stop and heat display does not work by lack of sensor, there is indeed possibility of serious engine damage.

Indeed Louis, thank you. I just want to let the fresh/raw coolant cool off and check the coolant level before i open up the impeller.

What normally happens when an engine doesn't automatically cut off at high temp? Does it blow the gasket and put exhaust into the coolant?

Nice to hear from you again, Slavko. 

The smartest thing to do would have been to first check if any water came out of the bleed valve, yes. I just checked, now, and nothing came out. No fuel no water. So your Slovenian wisdom, hit the nail on the head, slavko. And Vladan was very close.

I checked the impeller. It is fine.

Unfortunately i just removed the second stage filter from the engine. So the entire fuel line will need bled.

So having NEVER bled a fuel system before, or changed ANY fuel filters on this engine, before, i am now in the rather difficult predicament of drifting off the coast of Italy with a double fuel filter change and a fuel line bleed, required.

I know the fuel tap that shuts off the main fuel tank. I know the water drain valve on the first filter. I know the uppermost bleed valve on the second filter.  I know the manual fuel lift pump. I have two new filters.

If anybody thinks that i need to know whereabouts of something else, to do a successful bleed, please let me know.

Hello,

to me it sound like a diesel problem. Did you check water separator filter, if you have one?

So, the fresh water coolant is at the correct level and is not contaminated.

The engine doesn't start. It always started first time, Mr Perkins.

Houston we have a problem. I will ask Bill for single incident cover.

Thank you, all.

Hello Daniel,

This indeed sounds like a water pump problem.

When restarting the engine, look at the exhaust to see if the intermittent water flow is normal. If the water flow is erratic, this looks like an impeller loosing one or more vanes.

Hopefully, you have a spare onboard and can change the defective impeller. If there is swell, heave-to to stabilize the boat.

Good luck!

Thanks Vladan. I will do after I have let the coolant cool down. 

The engine definitely overheated. The new tubs of engine oil are even hot next to the engine.

Anette says she checked the temp about ten minutes before it happened.

I thought an over temp alarm would sound if this happened. I should have checked this was functional.

Should i expect a complete engine rebuild out of this?

Check the diesel filter.
