This is an all stations broadcast to try and help solve our engine problem. We are still stuck in St Lucia and have tried everything we know to get the engine running properly again. Can You HELP.
If you can’t help but you know someone who might be able to throw light on the problem then please forward this messgae
Engine History. Perkins 4.108 Diesel
The engine was running fine with no issues except a small leak from the fuel injector pump. We had the injector pump serviced in Las Palmas prior to crossing the Atlantic with the ARC fleet. The new pump was installed 2 days prior to our departure so we did not have time to test it out fully but it sounded fine and seemed to be running smoothly. The engine and gearbox were working together as when the engine over revved the speed increased accordingly in both forward and reverse gear. The engine always sounded sweet and smooth, with no banging or additional noise even at these very high revs.
The Problem
Soon after leaving Las Palmas the engine would start over revving independently of any throttle control. Intermittent to start with but as time went by the problem got worse. From idle to 4500rpm in a matter of seconds. Disconnected throttle cable just in case this was an issue to manually control revs but the problem still existed. Throttle cable not the issue. When over revving the stop cable was used and the engine stopped with no problem. The engine would start again each time with no problem.
What we have done so far.
As this problem only started after the new injection pump was fitted this seemed the obvious cause of our problems so we have now fitted two serviced injection pump and the problem has not gone away. In fact with the most recent pump installed the engine would run away in neutral but when any load was applied in gear the engine would struggle and revs decreased. So far we have checked
• Replaced fuel injector pump twice
• Fuel lines into and out of system, all clear
• Bled the fuel system fully
• No fuel contamination
• Checked fuel filter
• Ensured air intake is clear
Conclusion, Too much fuel is getting into the engine, possible cause which has not been looked into yet is blocked fuel injector or injectors but to have 4 injectors blocked does not seem possible. If one or two were blocked the engine would not sound right but when it over revs the engine sounds fine and smooth just running too fast,
Help. If anyone has experienced a similar problem or knows anyone who can throw light on this then please get back to me.
Although we are stuck in sunny St Lucia we did not cross 3000 miles of Atlantic Ocean to sit on our backsides and would love to explore the Caribbean but until we get an engine that works this is our home.
Thank you for your time reading this and hope maybe someone out there can solve our problem.
Take care in the winter storms in the UK.
