I have contacted my local dealer today, so far they have not come across the problem. I have send the bulletin number in LTB00196 and they are now contacting LR Norway... fingers crossed

Quite an interesting problem this since it has been recently highlighted on the Mudrut Arctic trip. Where exactly does the end of the breather come out? Can it be relocated to avoid wet air getting in and freezing? or is the damp actually being vented by by the Puma engine?

So reading the bulletin do I take it that the heater element in the breather hose is only working when the engine is running? does this mean when the engine is cold (ie standing over night) that ice can still form in the hose in severe conditions? Mermoto |

the defender is tested to -40c ** updated ** The breather pipe runs from the rocker cover (just behind the pasty warmer) to the back of the airbox unit. From what I have read, the problem seems to occur due to the cold air in the airbox meets the warm air from the breather pipe, and ice forms - eventually blocking the breather and causing pressure in the engine. D44 sell a heater kit to fix the problem in the form of an inline heater unit. It's wired into the heater terminals, so the in-line breather heater is activated when the heater is on in the vehicle. (makes sense) Just to add, I have a MY2010 Swiss 110 and it has not got the modification as standard. |

Here is mine breather heater - it is consists of relay, cable and in-line heater itself. The heater itself is under the pipe unsulation - I marked the place.
Fitted as standard, 2010MY. I fitted pipe insulation on breather for additional confidence Also for cold climate you need to fill the gap under the bonnet, because breather is almost exactly facing that gap. Click image to enlarge Puma 110 |

remove the breather and put a small K&N filter instead? As we have fresh engines they should breath heavy anyway so a small filter will be suitable.http://www.knfilters.co.uk/search/universal.aspx

thanks Denis, looks like a good idea to insulate the pipe too. Do you use the LR in-line heater or something else ? the LR fix wires the in-line-heater into the cabin heater electrics, so that the heater is on when the cabin fan/heater is running .. how have you wired yours ? |

Heater was in place when I bought truck in 2010 from dealer, it is genuine LR and yes it is wired to cabin heater through relay on photo. There were many Puma Defenders in Russia in 2007-2009 with oil off engine (sorry for my english ) due to breather pipe. As far as I know no one was when idling - all on speed about 80 km/h and higher and cold conditions. Cheers Puma 110 |

Yes I know! Now other changes! Other small modifications are self-made: 1. self adhesive rubber sealant (for doors and windows) - on perimeter of bonnet 2. engine blanket - is merely put on all engine bay 3. radiator muff thats enough for -30C - tested have some photos - if someone interested cheers Puma 110 Last edited by Denis on 12th Feb 2012 5:42pm.
