My old faithfull 3.0TD (2001) threw a wobbly this morning, absolute *beep* to start then cylinders cutting in and out at random - white smoke (£££££'s) flying out the pipe......settled a bit - went for drive - running perfect when warm. 1 hour later - started up - same again! *beep* to rev - loads of fuel/smoke
Tried the local specialists to get a code scan - wont touch it! called main dealers - cant touch it for 3 weeks and even then its a £100 for a scan!!!
Any suggestions folks? hope to god it's not injectors or its going for scrap - just spent £1000 on doing the head/glows about 1000 miles past and another £900 on wheels/tyres

Just occurred to me - it was an aftermarket - but supposiely quality - gasket set we used - could the copper seals/gaskets at bottom of injectors have failed????

OK - assuming copper seal failed - is fuel just dropping into the cylinder and burning off? and then as cyl heats up copper washer is re-sealing and allowing to run fine? does this sound about right ??
Do you folks supply quality copper seals then?

Further to post - gone out this morning to move it to fit new seal from Dealers - bleeping thing will not fire up! and dipstick was below min level - was full before last trip of 120 miles! It tried to catch first couple of turns then just turns over - anybody? cant be that all 4 injector seals have failed at same time reducing compression - can it? Can the system have coded itself into non start/safety mode of sorts? - the oil level was topped up BEFORE we tried to start - so ORPS should be ok.
nb - no cross contamination in water or oil.
Cut the white wire - no change
Glow plug fuse now blown - changed - got power - no change
Brake lights - working fine
Intercooler off - EasyStart down its throat - Crash!! bang!! thought it put a piston out the side....- nothing - still not start but definetely does not like this stuff

The falling Oil-Level is potentially serious. It could simply be a leaky gasket somewhere - so do a careful check for signs of a leak. The HP-Oil-Pipe would be suspect #1.

The only other simple explanation is BURNING the lubrication-oil! Then it's likely to be the piston-rings are gone or the bore is badly scored - either should show up in a compression-test.

have you tried the extra 2 litres above the max level

Just took 2 litres to get to top of dipstick level - is another 2 litres not going to cause problems elsewhere in system? It's never had that much oil in it before - and it was fully service just 1000 miles ago since when it has run perfectly.
Assuming I then have all this excess oil in motor and it starts - would the low oil level have been the cause of misfire that started this chain of events?
I bow to your intimate knowledge on these matters - just trying to get my head rounds the whys!

Yes that's correct it's to make sure the strainer isn't broken or sucking air past the seal. If it starts and runs then it's sump off time if it doesn't then remember to drain the extra out again

Don't worry - Eithan is NOT messing with your head! The EXTRA 2 litres of oil is a SHORT-TERM test-measure - specifically to check if the 'suck-up-tubes' in the sump [2 strainers which look like inverted funnels] have become leaky. If one, or both, were LEAKY - then the oil would not draw efficiently into the PUMPS. By putting in the extra 2 litres, you are raising the oil-level above any potential 'hole' in these strainers and so 'guaranteeing' oil-supply to the pumps.

As the fuel-injection in the 4JX1 engine depends on the engine-oil for its hydraulic operation, the extra 2 litres ensures a good supply of oil! If the engine were to START, with the extra 2 litres in the sump, then you'd have proved that a leak in the tube had caused the problem - and then you'd drain out ALL the oil - fix or replace the tube[s] and replace the oil - up to dipstick MAX.

When I first read that overfill suggestion, I thought you guys were messing with him.

Brought back visions of my buddy's old truck that he switched to 50-weight oil and overfilling by a liter just so he wouldn't have to stop as often with the blue trail of smoke flying behind him.

That is actually a brilliant way to test for that particular problem.

Gribble · Posted: Fri Mar 28, 2014 18:33 Post subject:

Its quite simple , the gear pump that supplies the HPOP is about 2 inches above the oil level so the extra oil covers the pump inlet so its not pulling air in if the O seals gone hard or the suction tubes cracked ,both know 3.0 faults .

Replies are much appreciated lads - took a chance and got the RAC out since the guy who showed up to do a code read only had the new MDI system - turns out RAC scanner does not read either and they have got NOTHING on their system for Trooper faults whatsoever - another 2 hours wasted.
Tried the extra oil today - nothing - still turning over - no smoke so obviously no fuel! then 90 mins with oil extractor to get it back out!

Still leaves us with the problem that we cannot get anyone to run a diagnostics on it for us anyway - and getting it to the dealers in a definite no-no - even asked if we could hire a held held - again no chance - anyone near Glasgow/Newhouse J6 M8 got the kit? Was even going to buy a clone kit but every other forum says waste of money.

Ref sump pipe split - what parts/costs are involved and can sump come off in-situ?
