Oh no that's no good mate
 silver lining is A1 head from now on  Turner are a good company used them a couple of times.
You going to hone your cylinders, mod the exhaust manifold or anything else whilst the head is off? |

I'm considering de-webbing the exhaust manifold. Looking into upgraded manifold bolts, just starting to search around for information on them. Anyone with info, please feel free to chime in.
In regards to the de-webbing, I know some have completely removed the webbing between the ports, some have just made a relief cut in the webbing between ports. Anyone have any experience? Pass it along.... Oh, I do have a stage 1 Alive chipped ECU I am wanting to install, figured there's no point until the new head is on. it's a Landrover thing... my renovation thread: http://www.defender2.net/forum/topic40792.html |

I still think I am going to have to replace the head on Miffy (not he funky white rabbit) as I am getting over pressurising still post installation of a new water pump. Before going there though I have to replace the threaded core/drain plug as it is possible that it might be the cause, letting air in to the system. Possible I guess.
If it makes you feel any better CDN38 I will also have to whip off the exhaust manifold again. LR really should have installed a quick release mechanism for this manifold, would make our lives much easier. |

I may have also been sucked into this sad tale.
Top hose burst/split a couple weeks ago, replaced it with silicone jobby. snapped the expansion tank plastic pipe in the process so swapped new in for that as well. Im now getting leaks/drips from (as far as I can see ) the bottom of the rad at either side when system is pressurised. not sure if the rad should look like this .... Click image to enlarge all bendy at the bottom. this is either a series of unfortunate coincidences or something darker! I had a new head and gasket etc done in august last year as it was cracked. its a 4A VIN so guessing it would have had steel dowels anyway? Temp gauge is always left of centre when up to temp and has been since I've had the vehicle so no change. No blow offs from exp chamber, just the usual hiss on engine stop. I was sort of in denial re HGF 7 or 8 months after new head but now rethinking. Also yesterday took for a run and had power loss /hiccup for a fraction of a second on dual carriageway doing about 55-60 before resuming but no flicker in the temp gauge.

 How the heck did your rad do that?!
Have you replaced your water pump recently? Apparently when long in the tooth these can sieze when hot causeing over-pressurization of the coolant system. I replaced mine last month along with the PAS pump as the dog gear was well worn, indicating something not running true. Also check that damned coolant drain plug under the exhaust manifold. 4A VIN should be metal dowels, plud if your head was replaced last august it should of had them replaced at the same time. Viscous fan nut. Have you the correct spanners? are you turning the nut the right way? TD5s have a normal right hand thread. |

Do you have a source for the gauge? Or a VDO part number? Looks a good match for the standard Td5 gauge set in terms of appearance. |

So new rad- not really digging the moulded look.
I saw your thing on the water pump - my PAS pump is due for a replacement as its got a slight leak in the castin, it scraped through MOT cos it is slight so its on my list for things to do may as well do WP at the same time, I dont think its an expensive part. yeah got the right spanner although this is the first time I've used it in anger - just cant seem to get enough leverage. 
coolant plug all good. cheers rob Disco 300TDi XS - Gone Disco 3 SE manual - Gone 😭 Freelander 2 SE manual Defender 110 TD5 DC |

Buy the best water pump you can afford. There are some pretty rubbishy ones out there which are cheap, but don't last two minutes.
