I'd be a little surprised if it was the head gasket, as I understand them to be pretty reliable on the 15p engine.
I wonder if it might be the water cooler on the EGR system at the front of the engine, which has corroded and allowing water into the exhaust that way? If its letting water into the cylinders via the intake, it might explain the rough running and white smoke. Is there any evidence from the water bottle of abnormal pressurisation? 2005 Td5 90 XS 1989 V8 110 CSW |

Skimming head, according to the manual...no.
Did mine (had it done) and seems to have worked +25k miles. Replaced the plastic head locating dowels with steel. Mine had a crack in an exhaust port so different symptoms - ran ok but just blew out the coolant if revved. Hope it works out...

Have you put a new and quality fuel filter on it recently?

I’ll take some photos tomorrow of the engine bay. There did appear to be some seepage near the EGR/intercooler hose. Nothing odd that I could see around the coolant reservoir. @landyandy: I haven’t put a new fuel filter on in the last 11 months that I’ve owned the vehicle. It was serviced the day I collected it. I do have a service kit on hand though (initially ready for the twelfth month of ownership but doing it a month early couldn’t hurt). |

My 15p 2003 TD5 head went with similar symptoms; don’t think it’s particularly rare. It had moved on the plastic spigots and was leaking around cyls 2 & 3 if I remember. The exhaust manifold had been leaking a few thousand miles before and was badly warped so I don’t know if there may have been some overheating.
Had a slight skim, new gasket and metal spigots; was fine for another 40K till I got rid. 2012 110 XS SW Orkney Grey 2003 D2 Td5 Black [SOLD] |

Are sure you had a new fuel filter in the purchase service? Many don’t bother.
I would start with that as it’s cheap, and easy (assume you know how. If not just ask) The 15p engines don’t tend to suffer head gasket failure much, and I thought it was the 10p engines had the plastic locating dowls and they were metal on the 15p? |

I'm his mate helping out - interesting yours went between 2&3, out of interest did diagnostic give you much cylinder misbalance in that scenario? Insta: @thebenjordan4x4 |

Hmm I'm not too sure. I'd have to dig out the invoices... wherever they are! Not the cleanest engine bay, I'll admit!

Perhaps my issue lies around here? |

Mini Landie if it was the head gasket your temp would rise quite quickly with rock solid pipes. and you would be topping up the coolant, left right and centre. Also you would find that you would be getting mayo around the dipstick and where you would top you oil. That's going from my K series days, when the gasket finally went, it was like a kettle boiling sort of speak, and it chucked the water on the through the weakest part of the coolant system.
So check the dip stick and the oil filler cap before you fire the engine over. 
Also fire the engine over too, and lightly squeeze the pipes as its warming up, that could tell you where the problem is. My K series had gone on the exhaust side.
if you are getting mayno around the dipstick and oil filler cap is, then the head gasket has gone. I have had EGR problems too with my 300, the motor was not really keen on moving. As there was a leak on the intercooler side of things. Also buy the blanking plates for the EGR and bin the system right off. In fact i would do that anyway, the EGR causes more sodding problems than anything else. I ditched the lot on the 300 TDI and i only have the coolers on the TD5, since i binned off the valve last year. Defender TD5 90 ---/--- Peugeot 306 HDI hatch back

Check for oil in the red ecu plug and maybe the injector seals starting to let go? Ray

Well it seems to have been the EGR cooler. I've purchased the X8R kit with the three blanking plates but have only used one so far as I can't seem to get the
 exhaust manifold end off due to lack of clearance for my tools.
I went for a drive around the block and noticed some small plumes of white smoke but nothing as excessive as it was. This was shortly into the drive, so I turned around in disappointment, but on the way back there appeared to be no more white smoke... so I carried on driving for another couple of miles around the block and still no white smoke! There was the odd puff of black smoke on heavy accelerating but nothing I don't think I need to be concerned about *touch wood*. The temp needle got to about 1/3 - 1/2 and stayed there. I also replaced the fuel injector loom with a used but good one and the fuel filter & air filter with new ones. I'm not too sure which single item solved the issue but I'm inclined to say the EGR blanking. I'll take the thing for a test drive at the weekend and see how it goes, but fingers crossed! |

for info not necessarily, temp gauge may not move over normal positioning but yes you would get rock hard pipes very quickly. you also dont always get contamination of the oil. Cheers James 110 XS Utility 130 Puma Station wagon/camper (in the making) 90 Puma Hardtop |

You should see the bottom of my air filter housing...
Got a little wet inside the cab as well.
