Hi guys. So my 3 litre trooper packed up on Tuesday after running rough and low on power all day Monday. Got it back home, had a look and found the diesel filter all gunged up, easy fix or so i thought, put the new one on, started to bleed the fuel and i noticed that it was coming out milky. The car will run fine if I run it off fresh diesel from a container. I havent checked the fuel return pipe yet to see if contaminated fuel is going back to the tank. Ive had a quick scoot around the forum with injector sleeves and head / head gasket the prime suspects. Coolant seems ok as is oil level. Just wondering what everyone's best guess was, thanks in advance |

well if you know you have filled up from a decent fuel station and you haven't been wading through rivers then the other way is it's putting it's coolant in to the fuel tank via the lower o ring on the injector sleeves |

Thanks for your reply Ethan. So I pulled the injector sleeves today. Very impressed with myself as it took 5 minutes using a hilti expander bolt and a tyre lever. Was then further buoyed by finding that a couple of the o rings looked pitted and split. Thought I would then look down the bores with a torch only to find a shiny reflection staring back at me in three of the bores. Am i correct to assume that I am actually looking down into the bores and that this is abnormal after pulling sleeves or does some liquid leak down into the cylinder ( did drain coolant out before sleeve removal ) |

You will get some coolant and fuel go down in to the cylinders and depending on how you removed the injectors, a lot or a little bit of oil would have gone down as well. |

If its in the cylinders yes otherwise you will get hydraulic lock when you crank the engine which can cause damage, |

Put the trooper back together today. Drained the tank , cleaned out the fuel lines, turned it over and about 30 seconds later it fired up with a massive cloud of smoke, which cleared, tickover a little lumpy for a while but soon settled. I ran it for half an with the diesel return pipe off and running into a bucket, the fuel ran clear, so connected it all back up and ran it around the village a few times and all seems ok. When i took it all apart down in the head there seemed to be alot of gungy diesel residue, I was wondering if anyone has any idea of the best thing to flush the engine with, or is it best just to use some coolant flush, also does anyone think that I will have problems in the near future with any of the hoses as after seeing how it has expanded the rad cap and lid on the expansion tank I think it may be advisable to possibly change some, many thanks in advance |

i have a good feel and if it feels squishy then i change it, but if it feels normal then i leave it alone. i run a decent coolant flush through it a couple of times then add the coolant, you can never get it all out but you can get as much as possible out, i disconnect a pipe off the manifold and one off the heater box and just let a hose run through and out the bottom hose. |
