From TD5Alive webpage: Why dont we make 'Big Bore' systems? A 3 inch bore system would not be appropriate for modern land rover diesels, since the turbo outlets are only 2 1/4 inches in diameter. Age old (Proven) tuning theory states that the optimal turbo down pipe should be 10% larger in...

Out of own experience it appears that those two blue o-rings in the injector harness cannon connector go under gauge fairly quickly (even if genuine or OEM) thus letting oil go around the male connector (injector harness side) and into the female connector (engine harness side). Have lately...

After years of outguessing Td5 fuel pump and/or fuel pressure regulator problems finally came up with a gizmo to measure live fuel pressure. In the past I had rigged up a mechanical pressure gauge (glicerine type) but for obvious safety reasons it could be only used in static mode (driveway...

Sierafery, I'm no expert and this could well be total blks but I believe the "peak charge long" and "peak charge short" faults essentially mean the ECU is not getting in the flywheel what it orders the injectors... The ECU is constantly listening, through the CKP sensor, to the result...

Back in July my Disco Td5 started misfiring & cutting out, not in the classic oil in loom way, but rather massively. Nanocom would show a scramble of the following fault codes: FAULT 27-01 injector 1 peak charge long (CURRENT) FAULT 27-02 injector 2 peak charge long (CURRENT) FAULT 27-03...

Assuming you meant engine pressure oil light and not transmission temp oil light, I'd look first at the oil pressure switch connector and harness. Oil pressure switch is located in the back of the oil cooler, down below the exhaust manifold between cyls 4 & 5. The connector has only one...

Agree with 8inaV, alternatively to a garage testbook, look for fellow enthusiasts in your area that own either Nanocom or HawkEye ('amateurish' diagnostic systems). Have a look here: http://www.nanocom-locator.co.uk

The EGR cooler is no longer connected to the exhaust manifold. Modified manifold prior to re installation: But Shifty you're right, supported by the fact that the EGR blanking kit came with 3 plates (1 for exhaust manifold & 2 for EGR cooler) did not bother to re route the coolant feed hose...

Just weeks after getting rid of the EGR & its ancillaries I get this... Surely the recirculated exhaust gas held counter pressure against the coolant side within the EGR cooler, but it shouldn't leak without it!! Wonder how close I was from getting coolant into the cylinders... Anybody...

There's a quick & clean way to check oil pressure. Just undo the oil pressure switch and hook up a pressure gauge, either straight on or with an extension hose in between. Should read 3 bar when idling (cold), and 1.5 to 3 bar at high rpm (hot). If below 0.5 bar the oil pressure warning light...

Indeed it looks like the coolant return pipe off the oil cooler. Recently did the oil cooler (leaky internal o-ring --complete post soon to come) as well as the exhaust manifold (broken studs) and took some useful pictures (turbo, exh mfld, a/c, oil cooler, oil filter & housing, centrifugal...

Sounds like a sticky glow plug relay. Please state auto details (model, make yr, etc.) so can look into relevant circuit diagrams.

First and most common reason for flashing M & S lights is a weak battery. The EAT (automatic transmission electronic control) is very sensitive to battery voltage. How old is your battery?

Engine has not been tuned per se (remap or chip), but EGR blanked off, turbo wastegate actuator rod adjusted a tad, & critical sensors are cleaned on a regular basis. It does not loose power, just flattens out in the same way it'd do when reaching 'normal' top speed. Have to disagree with...

I've been helping out a fellow Td5 owner with a performance problem in his Disco. It is a MY01 manual Disco with almost 120000 kms that has been thoroughly maintained. It pulls extremely well across the entire range (reaching 125 km/h @ 4200 rpm in 4th, which is definitely not limp mode)...

Update #2: Replaced crank sensor, thought I had it since the metal tip was literally buried in oily muck & the car ran smoothly for quite a while, but eventually the misfiring & cutting out returned... Currently waiting on new fuel pump, will open up FPR and inspect gauze filter. Also...

Update: Replaced fuel filter, no changes, engine still misfiring and shutting down when easing on or releasing throttle. Found some sort of black soot inside fuel filter & since engine was run on high sulphur diesel until a few months ago (low sulphur diesel previously unavailable in my...

Have owned Td5s for the past 10 years & thus seen the "oil in loom" problem revealed in various forms. As of today my '04 Disco Td5 started behaving extremely oddly, subtly clunky at idle (feels as if the vehicle is being given hand pushes from behind), then normal when given throttle, but once...

David, I know the place, been there for months... doesn't it sound like a stone in a tin can? Replaced: - engine mounts - transmission mounts - down pipe (de-cat'd) - mid silencer - exhaust system rubber supports Whilst all of the above improved the vehicles drive (it actually eradicated a...

ACE on my 2004 Disco Td5 quit working. No logged faults. Also no leaks, abnormal noise, wobbling, or any other of the traditional ACE failure symptoms. Simply feels as if ACE wasn't there ('passive mode'). Found out that whilst Nanocom can't connect to the ACE ECU with the engine running, I...
