dead TD5

[Graz]

The Toad has thrown a real sad. Travelling up the Armidale hill (Perth) it started to lose power, developed a tappet noise, got to the servo up the top and it stalled and started blowing steam and smelling expensive.

Initially I thought it had blown the engine oil over board for some reason as nothing seemed to show on the dipstick, turned out the the oil was so hot and thin that the level was not apparent.

So I guess it is coolant loss, but from where? ( Part of the reason why I didn't go on tyhe Pemberton trip was I hadn't time to fit the low coolant sensor kit:(.)

1) failed hose (nothing apparent so far)
2) Failed viscous fan unit ( didn't notice it kicking in when it was getting hot.
3) failed head gasket ( possible has done 192,000 ks)
4) other reason ?????

What worries me more is what else was damaged due to getting hot, cracked rings ETC.

Its pretty obvious the head is now suspect. I believe the head cant be faced, is that correct??
I guess I should prepare to purchase a new head at the very least?

What a bummer start to 2009.
Whats the Landrover equivalent for bugger?

Graz,
sounds like the head gasket at least, have you tried refilling the coolant & starting it to see if there are any bubbles in the header tank?

[mike 90 RR]

Seeing as you live up in the hills ... You would have got some sort of warning signs of getting hot before ... if the radiator was getting blocked up

So .... either a broken water hose .... or a knackered head gasket

Either way ... it's most probably affected the head, now that you boiled it


Can take a look at it for you on Monday if you get stuck .. as you live just above me

I'm going to attempt to take the head off today. Happy for you to take a look and get your opinion as to what the problem is. Sent you a PM.

Psimpson7 did a good write up on changing a head gasket, search or PM him

FWIW,

before you pull it down, turn the ignition on with the rocker cover off and pay a lot of attention to the top of the injectors. If the fuel pump cuts out cycle the ignition switch.

If your oil had gone as thin as your describing it, was stupid hot, and wasnt leaving a trace on the stick I have a theory that the problem may not have started at the cooling system. When you got the thing cool enough to be able to dip the oil and get a result, what was the oil level like?

Once it cooled a bit approx normal oil level appeared back on the dipstick.

I guess I will have other engine damage resulting from this.

Thats a top post from Psimpson7, a big help for whats ahead of me.

Does any one know the locking pin diameter for the camshaft gear and flywheel? (Landrover part LRT-12-058 and LRT-12-158 respectively)

Thanks

Stuck thermostat?

[PAT303]

Maybe everyone that reads this thread should book their vehicle in to get the cooling system serviced.It's only $250 plus parts. Pat

Fitted a new one just three months ago

parts will cost you better than $500 to do everything not including the coolers on the engine and the radiator.


yeah graz theirs going to be damage but I dont want to scare you but bare minimum will include the head gasket. Turn the engine over by hand with the cap off of the expansion tank then crank it on the starter for a few seconds and that will give you an indication of how bad the head gasket is.

if you cant or once you have remove the 4 glow plugs and try again, see what comes out.

Naturally if it sounds tortured when you bar it over by hand dont try it on the starter and once youve spun it over without the glow plugs in skip yourself a few steps in the manual and get the crank and cam in position by hand using a bolt shank that fits the timing hole in the cam mounts. (read the Rave first on head removal and that'll make more sense)

[Graz]

It looks like I have indication of water ingress in #2 cylinder and rust marks on the block on the L.H.S. of 1, 2 & 3 cylinders.

One of the plastic dowels had shattered and the oother had a large step.

Its a bit hard to tell as the head is not cleaned up and I only have a twelve inch steel rule but I can measure approx 4 thou " gap in the area were the water may have made its way in.

What this will ultimately mean, I don't know.

Is there a recognised TD5 head reconditioning shop in Perth who has the experiece to know if the head is scrap or not.
Thanks

On a side note, the head bolt torques were all over the place with the rear most almost no torque.

[Blknight.aus]

the loss of torque on the head bolts is an effect of overheating an engine with torque to yield bolts so dont be too concerned about that (although its worth keeping note of which ones were looser so that when you get the shape of the head face worked out you can compare).

you might have better luck finding a problem with the head by strong lights and a magnifying glass or jewelers loupe and giving the suspected problem area a MkII eyeballing.

[slug_burner]

Dave,

What are we looking for with the MkII eyeball? pitting? Is there something that the MkII eyeball will tell us if head is warpped?

[Blknight.aus]

what the MKII eyeball (eye assisted with a naturally iluminated observation device capable of close focus) should reveal is a pattern of erosion in the head this will be where the combustion gasses and the coolant have done their work on the head and should also be where the head is the most out of shape.

you may only be able to pick up the erosion as a change in the surface texture of the head.

[Graz]

Is there any differences that may prevent a complete Disco TD5 engine being fitted into my Fender. As far as I can tell from Paddocks there are two models of heads ( one has an external fuel return I think ???????)
As for the rest of the engine I don't know if there would be a problem. My 130 is a 99 build.
Thanks

[Psimpson7]

Graz,

That looks a mess inside. There is a lot of rust inside the water jacket also

You may just have to get it skimmed to find out. When mine had its moment, the head looked perfect to the naked eye with a 12" steel rule, but they still ended up needing to take somewhere between 5 and 6 thou off it.

If you can see abbout 4thou I would be concerned about it.

The general consensus of opinion is that about 9 thou is the most you can skim off.

The engines are very similar, and you should be able to swap one for another reasonably easily.

You would need to reset the injector codes in your ecu, and work around the differences in the fuel cooler setup and EGR but is should (is) be possible.

When Pulling the head down and removing the head fuel manifold I removed the O ring and pulled the filter base only to dicover there was no filter element. closer inspection found the filter element was a further 15 or so mm in.
Effectively there was no prtection for the injectors from any debris down stream from the main filter.
There is nothing in the service records to indicate that the previous owner had any work done in that area and I certianly have not touched it since I have had the truck.
I guessing its failed due fatigue resulting from vibration.
Might pay to check your TD5. Is only three bolts to remove to check.
Cheers
