Thread: KM's outof TD5

I gave him a new set of hoses, every filter, and all fluids, recoed the brakes all over. Greasable unis on the drive shaft. New Diff carrier bearings (should have done the pinion bearings as well it has to come out again.) All this took alot of time I have done it all myself and as a result know my truck pretty well. Barry will do 500K easy and we have a ball driving the tribe around in perfectly air conditioned Comfort. I am soon to restore his back end to SLS.

I figure he probebly had the head gasket done at some point. It might need to come off again to fix the oil leak, but I will be starting a new thread on that latter.

I am thinking about doing a compression test and if all is good I might Chip him. (Stage one)

How long do the turbos last? I have been told that Garrett don't make a reco kit, anyone else been able to reco their turbo?

Cheers

there is a reco kit for them... its only about $100 cheaper than buying a new unit by the time you get it delivered and have it fitted up (its about $250 cheaper if you fit it all yourself.

My money says that you are better off replacing the whole thing. if your going the way of upgrades save the money on the turbo and push it towards VNTing the thing then chipping it.

Ive seen a td5 turbo dead inside 50K Km but thats the exception to the norm looked after well I'd expect it to last to 500K Km but you will likely be noticing degredation from wheel wear at around the 300K Km mark (its a very gradual degredation so you probably wont notice it untill A, you have to pull the turbo apart for bearing/seal work B, you replace/overhaul it and your lag shortens up and you pick up 2psi of boost

Back home so I can upload the Tech Bulletin.

As it specifically says

'CAUTION: Td5 derivatives prior to the above VIN ranges must not, under any
circumstances, be fitted with the new steel dowels. If steel dowels are fitted to
earlier engines, cylinder head cracking may result.',

I have decided not to replace mine.

Thought I would re hash this post.


Having just brought a D2a with 345k kms and about to embark on 6k trip from Melbourne.

Will post as I go along, by the time I get home it will have over 350k kms.

'CAUTION: Td5 derivatives prior to the above VIN ranges must not, under any
circumstances, be fitted with the new steel dowels. If steel dowels are fitted to
earlier engines, cylinder head cracking may result.',

I assume that the "NEW" steel dowels are longer than the old steel dowels and the old dowels stick into the head of pre 2002 as the holes are machined deeper..

My VIN is in the range of 02 .

Does anyone have the dimensions of the old vs new? So I can check if I am getting new.

BTW mine is 178KK with no water usage other than that oozing from the right angle hose from steel pipe to water pump from the reinforcing material . It uses about 1teaspoon full in 6 months. And it is an OEM hose.

I did a bit of a google and found some info, including this photo from Landyzone which looks very much like a distorted steel dowel.
So where does that leave us?

I have 392,000 km 's, original turbo. Some horizontal movement in the vane shaft, no smoke of any description issueing. Turbo lag below 1200 rpm. Has all the power I need for what I do. I prefer to drive the vehicle, not give it the berries. Having said that, I don't take impossible tracks. If I did, I would get a Perentie.

I believe trouble with the TD5 starts with trying to get too much out of the engine, any chip MUST come with an EGT gauge, and temps monitered closely. Just my thoughts, temperature is King with an aluminium head.

I suspect the reasoning behind this is the different expansion properties of plastic dowels vs steel. the steel will expand more therefore putting stress on the alloy. The holes must be sized accordingly in the newer steel doweled heads.

PS, Mine has done 276k so far without the head being done. Touch wood!

Happy New Year to all. My 01 D2 td5 auto has done 323k, It is still on the original head gasket. We have just completed a camping trip from Seaford(vic) to Nelson back to Seaford to restock then straight up to the high country(howqua) and back home about 1600ks towing a junko hawk outback camper that weighs 1500kgs. We averaged about 14lt /100k. average speed of about 80kph. I bought the disco with 98k in 2008. Its running 32in bfg km2s, 3.9 great basin c/p's, rear ARB locker, 2inch lift, bull bar & winch. Hope i haven't jinked myself .Planing on doing Cape York later in the year(no van though) Still love it Cheers Ben.
