Going to get mine replaced (04 4.4 petrol) and was wondering if I should buy anything other than the valve itself - recall hearing that the connecting pipework often needs renewing as well? Anybody know which pipes and where is best to buy them? |

Many thanks nicksaab - most helpful - managed to get all but one hose in blue Silicone for under £30 the lot. |

Just a little caution -- my hoses needed to be replaced so thought I'd do the valve as well -- so I set off to my trusty mechanic with all parts in hand -- he's been mechanicing for 40 years, and I have 100% faith in his ability!

Do the actual valves wear out then? - would I be safer just changing the pipes or would that be false economy - considering suggesting to my mechanic to try removing the Torx but if one strips then abort the job and just do the hoses.BTW - bushy30 if you want to sell your spare please let me know how much you would like for it. |

Thanks Bushy. I can see why I couldn't find it - the item's images in the emissions control parts page and the inlet manifold parts page are totally different.

Storey Wilson suggests they should be changed. See Ron B. VK2OTC 2004 L322 V8 Auto 2007 Yamaha XJR1300 Previous: 1983, 1986 RRC; 1995, 1996 P38A; 1995 Disco1; 1984 V8 County 110; Series IIA |

Bruno, it's the rubber diaphragm that breaks down, so yes -- Storey does say that you can swap them if the unit you have can be opened -- my replacement couldn't be opened, so haven't tried the one on the car -- I ended up simply changing hoses and cyclone.

Duckworths were asking £112 for the valve and £12 for the thin pipe - ebay trawling got both items, inc postage, for under £60 - running my car on a tight budget so every penny counts. |

Have a go doing the thermostat mod / upgrade there’s plenty of info here on the forum. Essentially it’s a lower temperature thermostat that opens earlier and prevents overheating, there are a lot on here that have carried out the mod and had absolutely no problems. It’s a relatively easy job and if yours is goosed anyway.......... ______________________________ Simon ______________________________ Range Rover Classic 3.5 efi - Gone Range Rover Classic 3.9 efi - Gone Range Rover Classic 4.2 LSE - Sadly gone Land Rover 110 3.5 - Gone Range Rover P38a 4.0 SE - Pleased it's gone Range Rover P38a 2.5 DHSE - Just sold Range Rover L322 4.4 v8 Petrol - Current |

Thanks Simon, and good idea -- apart from the fact that I ordered the thermostat and had it delivered already

That’s a shame the mod really does take the strain off the engine, I’m not exaggerating when I say that the first time I started the motor and took it for a run I really could tell the difference.
