It’s back! New cylinder head for this GTB550 Defender Td5

The Td5 that just keeps on giving!
By the end of this episode, we’ll have replaced every component in the fuel system of this 90, except the fuel lines, and even they’ve been cleaned!
It’s certainly not a case of us firing the “parts cannon” at the car either, as you’ll have seen in the previous two episodes of this Defender, we’d actually found fault with each component and symptoms improved every time.
By the end of this (dare I say it?!) concluding episode, the engine behaves perfectly and the 90 is delivering incredible power with our signature, smoke free tuning.
This is also one of the first customer Td5’s we’d tuned with our new Power Flash system, which has a ground breaking secure method of deploying our very latest super clean tuning.
Grab a brew, sit back and enjoy as Stewart takes you through this final instalment.

Tony will be grinning from ear to ear! Sounds sweet!

Awesome video and thanks for the diagnostic breakdown. Plus the sound the TD5 with 550 turbo is just fantastic 😊😊

[@OTR-UK]

Great video guys, can't wait to get mine in.. once the build is finished.

I just got back from Morocco 3 months I was there, just me and the wife in my 110 td5. It’s totally standard mechanically with some nice heated seats and mirrors along with a heated screen, for Uk use. It’s got a roof tent and cooking gear in the back with a jackary setup for power to the fridge and lights etc and to charge our kit. Everyone said don’t go on your own you need others in case of a breakdown, 2,500 miles down the same back plus all the driving around down there in the heat and I had it serviced at Ali Nassirs garage for the trip home. There were loads of Landys down there and nearly all of them had issues but not mine because it’s standard, all these others with power tunes and lift kits winches big fat tyres were snapping shocks, one shredded a diff pinion because he had big fat tyres in the sand, nearly all were over heating but not mine, you can keep all this over priced suspension and upgraded ecu stuff it’s bollox, you can’t go any faster than granny at the front of the queue and offroad these tunes and big wheels and lift kits don’t give you anymore ground clearance, it just stresses your cv joints, diffs and prop joints and shock ends. It really is a waste of money but sat in the car park revving it to the rev limiter till it pops makes you look cool I guess. I towed 3 big fat landys to Ali Nassirs place with my standard td5 110 and very kindly towed a camper trailer back from Morocco to the port of Roscoff for someone with a 90 with a big turbo, stage 1 tune, silicon hoses everywhere that boiled and died and had to be recovered back to the UK.

My TD5 110 was ecu upgraded with a 2 " suspension kit and running 265 × 16 tyres 20 years ago and still runs well..

Excellent video, just shows chasing the big BHP shows up the shortcomings in your original engine!

[@_marcus_does_]

Great, want a 350 for my discovery later this year

[@matthapaq9618]

Mate it’s very great videos 💪🥳 , my question is if I bout a td5 NNN ECU and it was mapped from previous owner stage 1 or 2 i don’t know? If I bought it do I need do anything either installing it ? Cheers Matt

[@497adam]

Are the AMC heads as good as genuine ? Do they flow as well?

[@JimBiddle.]

So the gains were the AMC head? Full set of OE injectors in the last one, AMC head in this one, customer must really love his old truck. Be interesting to see how it gets on, reliability wise. Keep meaning to ask, is there any point in "Rolling coal", as in appreciable gains in HP?

[@TheMachine4ever1]

Do you use the cam number markings to line up the cam to the highest point?

[@AlexSharaz]

When fitting the camshaft, what lubricant are you putting on the camshsft casing and the cam lobes?

[@lawrencethompson6395]

Hi Stu great video. If you have a TD5 10p can you add the 550 turbo ? If yes does that mean getting the 15p ECU/ECM? Can you use the stage 2 map or does it need a full stage 3 map… not certain of the path? One last this when do you have to change the cam chain for safety so doesn’t let go?

[@alivetuningltd]

Give me a call to discuss Lawrence 😊

[@elliotpreston582]

Please could you let me know what wheels and tyres these are, size etc thanks

[@timoplants5869]

Can you clarify if the copper washers were renewed after installing the new injectors or were the ones you showed the original ones?

[@alivetuningltd]

Yes renewed with genuine seals

[@TheMachine4ever1]

Do you upgrade the valve steam guides to a better material?

[@alivetuningltd]

We’re not aware of this being an issue?

[@allthingsadventurous6568]

Wouldnt new injector seals have fixed it?

[@alivetuningltd]

Unfortunately no, it had had those previously, in the last video of this car.

[@allthingsadventurous6568]

@alivetuningltd Ah, sorry. I must go and watch that one. Thank you

[@ianwheat1577]

Ate them washers on injectors cheap copper covered steel one's

[@alivetuningltd]

We only use genuine LR injector seals.

[@ianwheat1577]

No good chucking parts at it need to diagnose then replace parts

[@alivetuningltd]

Watch the previous episodes on this car. Pretty much every component in the fuel system was faulty, and you’ll see how we document the improvements as each component is replaced.
