Hi mate great work much patience and determination shown great job turbo side is the hardest area to work in, Changing the oil pump same time as the belts is something I would always recommend on tdv6 most belt failures are due to idler or tensioner failure. You can pick up a genuine fomco oil pump for around £150. I have been lucky with my electronics so far, most things have been plug and play, what diagnostic device would you recommend, i only have one of those Isoft, for d3.

many thks and indeed ref the turbo area a right nightmare for access

bless u and ur be surprised even though there’s so much info on the web giving warnings about the oil pump there are still people who simply ignore the facts and then complain when there engine goes bang , think the rough price these days to have the timing belt etc replaced is just under 1k , far cheaper than a new engine of around 5-6k

personally I’ve got a gap iid , alas expensive but in all honesty pay for themselves very quickly , can get them for around £450 but considering an average diagnostic fee is around £100 it only takes a few plug ins to get a return on ur investment

Plus the gap iid customer support is second to none based on Canada they will reply to an email normally within 24hours , scanner will do virtually everything ur ever need, including programming a new key and re calibrating ur suspension

I got a new key and programmed it which excluding the cost of the scanner came to under £50 , dealer wanted several hundred pounds so even with that saved a lot of money

plus of course at the end of the day it’s the convenience of having the scanner to hand , not having to wait for an appointment or wasted time

plus out of curiosity what tyres have u got on ur D3 please , I’ve got a set of 19’s I’m going to fit , mainly so I can then do the V8 brake upgrade , tyre make wise I more than likely get the falken wild peaks fitted , there snow rated as well and leave them on all year round

will then get rid of my 17’s as I’ll have no use for them, have cooper tyres fitted which must be 5 x years old now but look brand new with the amount of tread they still have

so for me my future plans are , tyres, timing belt and pump, wishbones then brake upgrade

still want to get round the bits I’ve got , ie, fitting the soft nudge bar, sliding boot floor , D4 xenon’s and front D4 wings

hope all is going well on ur project mate

Hi mate glad it seems to have come good for you, Thanks for that will check it out, been lucky so far most things have been plug and play my i tool does resets, steering angle but to my Suprise even after a year they just come back to life I have a Frend at the local garage who has the delpi system so have a backup. I run 18s and like to use continental myself premium for mid-range price, but I do more on road than off, 19s will give it a great stance are you doing a mild lift sorry can't remember if you already have? Oil pumps (every belt change and do that early) frequent oil changes are your best shot at keeping a health tdv6 (have seen a couple of blogs where people are running 10-40) nearly all the tdv6 motored things I have bought broken have not been serviced maybe the first two or three. At risk of ridicule the tdv6 is a different beast of an engine and needs to be treated like a high-performance motor, it is fickle but the 3,0l in a jag can do 147mph allegedly is this not impressive, the more power the more stress the shorter the life of the motor particularly if not serviced serviced serviced, going in workshop now still have 18 valves to grind in, but the heads don't need a skim also have a lot of cleaning, fia gaskets and bolts on the way, Once again happy to hear everything has come good for you it's not easy to do the things you did I wish more people had your grit particularly with your back issues Top job mate

many thks for the very kind words , just refused to let it beat me, alas took forever but comfort knowing I’ve saved a lot of money from labour costs , dread to think what the bill would have been , must confess since doing the interdooler hoses, fixing the ear air leaks on the throttle body it pulls like a train , a lot smoother and quieter

indeed regardless of yearly mileage which can sometime be under 1500 miles i change all the oils , filters etc in the engine , transfer case, front and rear diffs etc , fuel filter every other year

been using millers EE performance 5/30 engine oil , funny enough also seen that where some people have changed there engine oil over to the 10/40 , personally have stayed with the manufacturers recommendation, know the millers is more expensive than other oils but considerably cheaper than a new engine

I haven’t actually regarding lifting , as I don’t do a lot off roading won’t bother fitting the longer height rods

put a pic of the 19 inch wheels I’ve got , will then do the front brake disc V8 upgrade , rears I’ll then do later on

remember that well with lapping valves , hardest bit as u know is trying to keep that rubber cap on the end, lol

Many thks again and following ur thread with great interest

Wheels look in great nick, hopefully you'll post some pics of brake conversion I'm most interested seeing how it's done. Think I might change to millers too heard lots of good things, oil is the key, I change every 6 months regardless of milage, I suspect you probably saved a £1000 wouldn't be surprised, I heard LR charge £3000 to supply and fit a turbo. Good job mate bet it's nice to be back on the road

Must confess got very lucky with regards to the new rims condition , got a set of x 5 and got them off another D3 owner

no probs and will indeed post some pics up when the V8 front brakes are fitted , advanced do kits which include the V8 caliper carrier where it just moves it slightly further away to allow the bigger discs to be fitted , here’s the link in case u haven’t seen it

https://www.advancedfactors.co.uk/front--rear-disc-upgrade-kits-to-v8-size-12793-c.asp

also thought about the drilled and grooved discs but heard they can get hairline cracks along with rust build up in the holes and grooves , meyle are supposed to have good reviews on the twin vented discs

heard that as well with regards to a new turbo fitted

been using millers for a number of years now and been very pleased with it

many thks and yes am over the moon it now has a new MOT , will be giving the disco a good test on some A/ B roads and dual carriageways over the months , think as well applying red grease onto the actuator arm has helped a lot over me previously using a no ark anti seize spray

plus along the way feel I’ve learnt a lot more than I did before , oh and found a general picture of the same wheels as mine fitted to a D3, will be really nice once I get a new set of tyres fitted on these rims , will go for 255/55/19 , can get a 60 profile but a lot harder to get and more expensive

had mine 6 x years now and must say after owning landis for over 30 x years the D3 is my favourite so far , like ur good self don’t think u can explain the sheer comfort and how it eats the miles up down the motorway with such ease , know the air suspension can sometimes throw a tantrum but so worth it considering how the air suspension soaks up the pot holes and bumps

Will have to fit my new rims / tyres first anyway before doing the brakes , then be the lower wishbones and finally the V8 brakes , heard they make the world of difference

must confess as a side note drives me nuts seeing low profiles on discos or range rovers

thks again and so nice being able to share information along the way

Thanks mate will check it out, aiming for mine to be finished in about three weeks most likely six lol. 19s give it a stance but don't look boy racer nice, also the lower the profile rougher the ride, only ten valves to go but I need a new lapping tool my old one gave up today split but have had it nearly forty years so got my money's worth
