td5 and 495,000 and the head gasget has finally gone

[cj5350]

So my 130 just ticked over 495,000 and on an easter trip away the head gasket finally went. I managed to limp it home and it drove fine ( besides wanting to overhead every 5 minutes) the decision is now do I just fix up the head and refit it on an engine with those K's or do i swap out the 10P for a later 15p or 16p with way less K's

My thoughts against fitting the head again is the engine had a few very hot cycles and at the end of the day... all of the accessories have done close to 1/2 million K's

Cheers

Your car since new?

if so, you'd have to be happy with that..[smilebigeye]

[justinc]

Mate it depends too on if you are doing it yourself or not. The costs of getting a workshop to do it i would be sourcing a used engine. The later ones aren't really any better for example the 10p heads are more robust ( unless you get a 15 or 16p with a AMC one already fitted) and you can buy an untidy running d2 with a road testable td5 for very little now.

Yeah doing the work myself...

495k
10p
plastic dowels
head shuffle
Yes I would be pretty happy with that to.
Says a lot about luck, or is that good management😉

Would be an interesting one to pull down to just see how worn it is
What oil was it using??

[roverv8]

so at 495, is that bottom end untouched... timing chain ect.
I put an AMC head on my td5 disco at 290, its now 343, just got back from Perth in it , 3800kms across, & 3350 home (direct) it used no oil & never missed a beat towing a camper trailer. i'd be happy if i can get up to half a mill out of it. i just had the auto rebuilt not long ago either...

Very good question! And maybe how often it was changed?
Also if it has been remapped?
Being a 10p maybe not as it should have the MSB ecu which makes it a bit more difficult.

Also if it has the original exhaust manifold? (not leaking).

Still, great to see that sort of life out of the TD5.
I plan on having mine for a few years yet ( Defender, 2002, with 130k)


Cheers,

If it was me, I would put another motor in.
Theoretical life from the TD5 was around 500k so its fair to say this one has theoretically served its life.:thumbsup:

Good second hand motors are not to hard to find around the 250km mark and relatively cheap
I think it is Gazk and outback1 on the forum are regularly wrecking Td5 vehicles and would be able to sort you pretty easy.

If you get a 16p and are keeping the vehicle, try to get the EU3 intercooler and ECU with the motor (if it is sourced from a Defender) and be prepared to run an extra wire or 2 for the later Ambient Air Pressure sensor.
Offtrack- forum member has a thread/tutorial.
It isnt necessary to run the 16P but you will enjoy the full potential of the newer motor and ECU refinements.

[YOLO110]

Thats great miles...

I would get a 'new' motor mate...

I once 'overheated' an engine after a blown head gasket... had the head skimmed and all re-built, but it never ran well thereafter and after a few thousand more k's, it seized! I think the overheating may have also shagged the block or other internals that were not designed to run at that high temperature.

[djam1]

Not saying that the 500000 ks life expectancy is wrong but why do we say this?
I have a MAN D2566 here that I think has done over 1 million and it runs fine (1.2 Million on the clock)

[cj5350]

Thanks all for the replies... was running Penrite hpr oil and all filters changed every 10,000 .. running a puma intercooler if the helps...
You can still see the crosshatch on the bores..

In that case, a new/rebuild head may well be a good option.

As Justin C and others have mentioned....
(**keep in mind, I do sell used TD5 engines, so some of my initial comments may seem a blatant "sales pitch")

*The cheapest n quickest repair is to swap the engine out for another used TD5.
*Even with freight costs its still cheaper to get a used TD5,
*I prolly do more "engine swaps" than head rebuilds, BUT to be fair its pretty well always a Discovery 2.
*Now saying all that, a Defender really is worth so much more than a common old Discovery 2, so personally I could think of no better excuse to do a full engine rebuild.... mmmm nice thought. [tonguewink][tonguewink]

As I say to owners, they need to consider....
*What they value the vehicle at. (not necessarily from a dollar perspective)
*Are they going to keep it, or sell it off.
*Do they need to just get the "daily drive" back up and running.
*How much have they already spent on it.
*Is it a worn out train wreck.

On the last point I tend to be quite blunt with owners, sure a lot of vehicles have some potential or worth, but if its a rolling train wreck they are better off putting the money towards another vehicle.

Whats a rebuilt exchange Td5 worth plus head?. Pat

[cj5350]

Thanks for all the replays and suggestions so far..
I have no intention of selling the car so I think I'll call it a day with the existing 10p motor and look for another..
Unfortunaly rebuilding is going to be to pricey plus a lot of the accessories have done a lot of k's as well so I'm leaning towards a later engine with lower k's

so far been I found a eu3 with 140,000 for 3,500 but would need the find a manual NNN ecu to suit

also been offer a 10p with 230,000 for 2,900 complete which mean I can still use my stage 1 MSB ecu

Well picked up a damaged discovery 2 with 212,000 only to get the motor running to find out the big ends gone so back on the hunt for a donor engine 😞

That post pretty much put to bed all the others on this thread... For goodness sake, it's an engine,, it's not a Saturn Booster. Rebuild it. Diesels are forgiving, and TD5s are amazing.

I think my first, and most important, question would be: what do I want from this car? It has a history of reliability; Yes? Half a million Ks on a TD5 is by no means unusual; Yes?

I would replace the head gasket, and drive the car around like you always have, while you think about it. Maybe your son will need to decide.

That sucks

[Tins]

That sucks

Especially at those ks.

[cj5350]

Thanks all for the help... finally got around to getting my 130 running again after having a few weeks working on a tdi300 130 I just pickuped for a mate..

i salvaged bits off the other engine and my head was barely 6 thou warped.... just need to swap the fuel pump now is it got noisy after having all that hot fuel running through it I'm assuming
