Hi all As the thread suggests, i want to fit locking diffs to my 300tdi disco after a sucsessfull head gasket change, thanks to all who advised me!! So whats the best method out there?? also do i have to uprate the suspencion, steering etc to compensate?? any advise/ help will be appritiated, Dave

if you can get a manuel, i had both and can honestly say there is a noticable difference in fuel consumption. the engines are strong, check for accessive smoke on start up/ heavy accelaration. check inner wings/body mounts in fact anything made of steel as this was the main problem

yep would agree to that!! just to let you know if you dont change the gasket you will get a mutha of an oil leek!!! when you undo the bolts you will break the original gasket seal, thats why the gasket needs replacing

if it hasnt been touched for twenty years your doing well!! i would remove the rocker cover, replace the gasket ( chances are it wil simply fall apart after many years of service!!) and replace the plastic washes on the cover and replace with new bolts

ok, heads off, cant see any visable cracks on the block or the head, after spending a good 3 hrs inspecting with a magnifing glass!! however, sat the head on a pane of glass, and its certainly not sitting right, only talking about 1 thou out, if that, need the magnifing glass to actually see its not sitting right, but something is defo amiss!! so will be refitting after taking it somewhere else to be machined, as for the cowboys that skimmed it the first time they will be getting a strongly worded letter. will defo be using new head bolts, new gasket, water pump will be fully inspected, and hopefully that will be drama over!! have found the relevent info for the torque settings and tightening sequance, will be buying an angle guage next weekend (back to work for me tomorrow ) so hopefully greenlaning again next sunday!! thanks to all for the info, hope to be of service to other people on this forum if i can be and happy new year to all!! :i-m_so_happy:

1.8 rover K series engines were notorious for head gasket failure, however, changing the engine seems a bit drastic to me as changing the gasket itself isnt too taxing with the correct knowlage! i would advise caution, has the new engine done 10k miles or was it replaced 10k miles ago? and if its the latter how many miles has the engine actually done. find as much history about the car as you can and ask questions! personally i would shell out a bit extra money and get a TD4, as the 1.8 wasnt the strongest lump, and if used for towing/heavy work it puts alot of strain on what basically isnt the best engine fitted to a 4X4

jet washed my 300tdi disco, turned the key............. and nothing!!! turned out i blew a wire off so replaced it and all was well, in all seriousness, switch off when washing, use a good degreasr (sorry cant spell!!) and before start up just check air intake pipes etc are all connected, also check all wires are as they should be and all will be fine!!! :i-m_so_happy:

sorry to say it wont fit, the middle belt on a TD5 is an inertia reel, the belt on a 300tdi is a lap belt, also the belt mountings are different as well.

yes was going to change the gasket as a matter of course, now realise i've been a bit foolish, read on the internet regarding a gasket change and then went ahead and did it, have done gaskets in the past on other vehicles so thought i had the information i needed to accomplish the job, however since joining this forum the info i had was totally duff!!! so will be using this forum for all my repairs in the future!! so sorry in advance for being a right pain in the a**e,but could someone please tell me the following torque setting for the head bolts, have read 3 different settings so far!! the tightening pattern :- been told to start with the centre bolts and work outwards thats pretty much what i need to know, have sourced a reconditioned head in case the 1 i have is buggered, comes with a guarantee so should be ok. still hoping the guys that did mine first time round messed it up though!! thank you to all for your help and happy new year to all!!

Well the plot thickens as you say!! Took the core plug out the top of the thermostat housing, revved the engine and water started bubbling up though it, so your right, there is exhaust gases presuring the cooling system, kinda new that really, was hoping someone would come up with a magic wand idea but already knew the eventual outcome!! So today the head comes back off, i have heard some awful reports about the company who machined the head the previous time for me, so kinda hoping they messed the skim up and theres no cracks in it!! will keep you updated, thanks for the advice, now, 1 final question.......... do i need to change the head bolts as its only a matter of weeks since i last did the gasket, on some websites is says the head bolts can be used upto 4 times, however, i am a firm believer of "change the head bolts every time"?

Injector harnees as bog monster said sound the most likely as it happened on my disco. After changing this if you still have a problem, try changing the diesel filter. Also on the TD5 there is a 1 way valve on the pipes going into the diesel filter. I had the same thing on my old TD5, could not find anything at all with it, was going to by pass the filter to see if this made a difference, thats when i found the valves on the pipes. Took the valve out and presto, 1 normal running TD5!! However they do need replacing as diesel then heads back into the tank from the filter, thus creating starting issues if left standing for a period of time

Could be one of the doors isnt activating the light out switch, am sure someone on here will give the correct name for it!! however if this is happening the alarm wont activate properly, and the central locking wont operate properly on the key fob too. Try dissconecting all the switches off the doors and then see what happens.

The radiator let go on a long run which in turn blew the head gasket, since replacing the gasket, and having the head skimmed and pressure tested etc, this is when it all started. when the gasket let go the engine didnt overheat as i noticed it in time. Is it possible to by pass the valve as its only a 1 way valve ie :- it only lets water pass through it in one direction?

posted a new topic relating to an overheating issue on my discovery 300tdi and wondered why its now been 24hrs and still not put up on the forums??

Hi all, right this is doing my head in!! I have a 300tdi that appears to overheat, the symptoms are feezing cold air from the heater with the temp guage through the roof, then a blast of hot air and the temp guage drops like a stone to normal. :wacko: Then after a while, the temp guage slowly climbs to red hot again and the heater slowly goes from luke warm air to freezing cold again. On removal of the header tank cap, with the temp guage red hot, it releases the pressure and the guage goes back to normal, what water comes out is warm/hot but not boiling, so the engine isnt overheating as such, more a massive build up of pressure. so far i have changed the following :- Head gasket (with head skim, new bolts etc) Radiator (new) Top and bottom Rad Hoses (new) Header Tank (2nd hand from a scrapyard, would a bit of plastic make a difference??!!) Thermostat. I have flushed the coolant system through a number of times with a hose to elliminate air locks, if its running low on water, the heater blows cold all the time but the temp guage stays normal!! Am now at a loss to know what to try next so any ideas/help/info would be greatley recieved!! Thanking you all in advance!!
