good code reader.

The rear crankshaft seal is the type in a big metal frame, the bolt heads holding it on are very short and are sometimes awkward to get undone, you may have to cut a slot and use a screw driver aswell as 8mm spanner... or they might be 7mm..cant remeber

Just to update this
Flywheel and starter finally on order.

Had it for a big road trip last night , i was managing to hold 60 mph with the colder evening air.

Just a question on diffs and remaps

Due to reasons of carraige im going to be swapping the internals of my diff rather than swapping over an entire axle... Transport to here would be just mad, Transits are not that big in France as they had the Renault traffic as van/tipper for the home market so sourcing a diff here be very difficult.


I have searched old threads but nothing too obvious is there. What i seem to be looking for is the sacred 4.63 internals that knock 500 Rpm off the top end which is just what i need,

I did a diff way back in the apprentice days so i know the basics, eithar way il work it out as have no choice, Iv got the dial gauges and that already

My question is am i looking specifically for a mk6 with twin wheels etc or does that not really matter since im only using internals, - Eg will my half shafts fit into a diff from another model , other era even a single wheel setup.

If anyone has info please let me know

I also read that a lot of you go to specialist transmission places where you can actually buy a crown wheel and pinion, are these made to order parts or ford parts or used parts or does anyone know what they are using,

I had a look on Ebay and the price for the 'Millenium' type crown wheel and pinion are close to 400 Pounds without a rebuild kit from a place called fast track bearings, normally ebay is cheapest for most stuff so id be interested to hear if someone has found a better option as the 'old' topic i was reading was mentioning around 250 for parts and fitted.


another quick question, has anyone rempped their transit by removing the Ecu and getting it 'bench flashed' since mapping mine through the EOBD port isnt possible as its too much road trip i think i may need remove the Ecu to post it somewhere

again love to hear from any that have done it. and indeed anyone that did an injector nozzle swap on a mk6.

Bon weekend a tous

I would honestly leave your axle till you have it 100% sorted specially on a tipper, plus im not sure wether you can get the 4.63 diff for the twin wheeler

My y reg 90ps jumbo with kerb weight of 2200kg has the 5.13 axle, and i can comfortably travel at 90mph, but flat out is just under 100mph, this is mainly because its a quiet running engine and has all the power it should have, i scared myself when i put my code reader on live data to see what the engine revolutions are at that speed and it was around 4k
towing a 500kg trailer and a 280 transit weighing 2300kg alltogether, so 4500kg GTW it still creaps up to 90mph when cruising.
When they are running right they seem to work well only using upto 1/2 throttle, when not they need over 1/2 throttle all the time.

obviously I normally only travel at 80mph max.

This guy is the best for postal remaps http://fordtransit.org/ad/redirect/29/ his user name on here is martynx.

If you get it all sorted then remapped, im sure you would benefit from the 4.63, allthough i cant say what it would be like carrying a lot of weight

I have a 4.63 full axle to go in mine but dont want to do it till i upgrade to 125ps then remap that...... or maybe ill do it before.

The 90ps i had before with that actual axle in was rapid, but never used it to carry a lot of weight or tow.

[twincamsham]

Sounds like i need to buy your tipper - prob cheaper in the long run lol !

was that 90mph on a twin rear wheel tipper with a heavyish steel dropside box? I could only dream of that sort of performance

You mentioned that your code reader tells you 4000rpm
was that the same codereader you sent me a link to ? Because if it can display 'live data' i was thinking it might be the job to see what the coolant temp and air temp sensors are telling the ECU

I had about 2.5 tonne in it yesterday again of sand , 40 mph sometimes 50 mph was all that was possible

i have seen one vehicle a fair bit quicker than another in the past but never such a difference as this, its pissing me off to be honest because to all the world it would seem to be running quite ok.

Ps for those of you interested i see mk2 mondeo td clocks seem to be quite rare on Ebay- they must be all in transits !?

There are often alot of counters such as they above on my local ads site, there in Kmh which is tip top for europe but not so usefull for uk, but for someone struggling to find some it might be an option, they seem to range between 20-40 Euro and then theres post so prob not the cheapest when it also works out- but depends how badly you want a rev counter! i managed source some for 20 Euro delivered yesterday - she seemed to have 1/2 a tank of diesel on the Gauge too so i cant loose


does it really make a difference to the diff center if its a twin single etc, all i need is something that i plug my half shafts into.
You would have thought that ford kept things fair uniform,

maybe im looking at getting a pinion and crownwheel, seems the best option at the end of the day since the rest of my diff seems ok, it started leaking recently out the pinion seal, oil is nice and clean but now less of it
so theres many things on that van that need pulling apart and attention,

Thankfully i got it at alright money so it does leave a bit of room for repairs, its not rusty and in this climate stuff tends to last for ever,
My 2cv AZAM 425cc ( 1963 suicide doors model) was pulled out of a barn after near 30 years with little more than surface rust on body and fethered holes on the boot floor, The old owner would turn in his grave if he saw the Smart Brabus kkk turbo that was being grafted on to the end of the line Visa 652 cc engine with electronic ign no less and a 3 main bearing crank ( old was 2 bearing- dodgy for boost ) ... cutting edge stuff , Flywheel is being drilled at present for pickup sensor, bellhousing modded to make room for the ducati v twin wiring loom and pickup sensors to run the the independant throttle body injection, goal is a savage 70 bhp pushing through the adapted Citroen GSa 4 speed box with inboard discs and rear disc conversion,
a 2-3 inch suspension drop will be the only external indication of the monstrous power beneth the bean tin quality bonnet...

Thanks for link, il get onto van tuner when its running right, no point tuning a vehicle that might be in limp home as you say,

Its too responsive to be in limp home but somethings not right,if you drive it foot to the floor it will roar up through 1st and 2nd gear no bother after that she sort of runs out of puff more so over the next 3 gears and if its anything more than flat ground youd be as well leave it in 4th

Maybe i could make a video of performance and host it,

4 years later and i sorted this by accident !!!

my problem - was caused by a plastic intake manifold being split open near half way around, so split open that there was no woosh to give it away , more a roar - sort of the same tone as the engine and easy to mistake for induction or just a noisy engine, specially since i never knew it another way ,

the cunning split along the plastic seam weld on this intake plenum , would close itself neatly when the engine was on tickover over or basically not on boost,
so when you have the bonnet up all looks well..

it wont necessairly be really oily as on boost you got valves sucking away and they will suck the heavy oil in before it gets squirted out with the escaped air.

So seeing as the van is now full converted to a LHD, i had the tedious task of getting in by the brake servo today to extract the cracked manifold..

got it in about 40 minutes, new one on, test drive - result, its like a different van, sails along on the turbo. its also got about 600 kg of tin in the back so looking foward to seeing it empty tomorrow on the drive home from tip ,

(this is mapped by vantuner )

4 years waiting for this day, im now happy with the old tddi, for all i use it for .

the only thing i would say is that it feels like its trying to go even more in first and second when you give it the gun , and then cuts back power slightly , like an over boost fault, but i dont think the ecu in these has much idea of what boost is at with the little map sensor.

My waste gate is screwed up to the last, would need a boost gauge to see whats happening, see if its dropping back fueling for some reason

does maxing the map sensor parametres by hitting max boost cause it to ease of fueling till boost drops back - anybody ?
should i back my boost down to standard levels, surely its not changing much

Anyway a happy end to a long and tedious tale, apologies for attacking the TDDi , it was my own stupidity , to proud a mechanic to find the simple faults and i never threw much time to looking at it !

those with dead tddi's beware your inlet manifolds, my old tipper on its new bearinged 4.63 diff gears is like a new truck, il sleep well tongiht !

Well well well, that took me a long time to read all that and there's a heck of a lot in there that went right over my head.
One thing though that put a smile on my face was the fact that you discovered a split intake manifold after 4 yrs. I feel for you in this because I too have recently fixed this same problem with my van. But I spotted that problem before I bought it and I knew that this thing was slow because of this. I am glad you did manage to get to the bottom of it

[twincamsham]

Tell me - was it worth the read ") !

Yep 4 years, dont get me wrong i wasnt looking for it everyday, i just accepted i had a slow bag of sh*t and had to use it anyway and i only need one tipper,

I was aware all this time that it was down on boost...but if you cut fuel delivery to a car you will also get low boost, so it can also spring from Pump or engine management.

Also got a vw t4 with an Ibiza Gt tdi 110 engine in it, there a boost gauge fitted, and i noticed when id hit limp home before fine tuning the install it would rev but the boost wouldnt build at all
boost needs hot gasses, not lazy oul gases, thats what i presumed the transit was pushing. just gone lazy

I might fit a boost gauge just to monitor it over time, at first mine wasnt all that dead, the crack must have slowly forced open over the years till it was obvious to see it !

i posted on many forums and no one suggested brittle inlets so hopefully my posts will be found by a novice , granted many people said boost leak but if your not a transits for life man your going to look at hoses and turbo and overlook what looks a decently cast inlet manifold unless you know

my friends laugh at me, but i must say i love that oul transit cus i stuck with it and right now im very happy with it, 2 tonne of gravel mix in it the other day and doesnt stress her at all. you feel like a real man when shes loaded up , dont use parking spaces, f*** her out in the road and put on the hazzards !

Even went to the bother during the winter of converting it from a RHD to a LHD, welded in bulkheads - parts of floor everything to get it factory as had a donor van and slapped on a mk6 front, id say she good for another 5 -10 years service yet and iv it working for me every other day.

A happy ending,

You were lucky you knew what you were looking for from the start !

[Andycush]

Brilliant write up and very informative, by any chance could this throw up FIP codes?a

[Jim Archer]

It doesn't seem to. My 125ps was proper split like the one above and still went well. Fitted a one I'd pressure tested to 1Bar to take it to Martyn for a tweek, and it split on the way ......

It's quite possible the 125 copes better than the 90s with this though.

All though I did in fact mention a split intake manifold at least twice
A code reader would of shown just atmospheric pressure too, to send you in the right direction.
Moral of the story don’t skim read (like I do ) and you won’t waste years of your life
