Td5 rebuild

**Dreamer** · 8th November 2010, 07:35 PM

I rebuild and repair machinery all the time, but am wondering how much a Td5 rebuild top to bottom might be. Vague but your answers might fill in the gaps.

assuming you dont have to replace any of the externals or the head...

$8k at a guess at reasonable machining rates.

Anyone bought a short motor How much?

What sort of k's are normal for a well looked after TD5.

I thought there was limited machine work you could do on a TD5, specical coatings and case hardneing and all that?

have often wondered about that, as the engine ages all that one can do I think is change pistons (but I am refereing to a Haynes manual - must get a RAVE some time)

interested to hear feed back

A new long motor from LR is less than $8000.

the block is similar to the 4bd1 in that you keep the block and replace all the internals. the cylinders are a liner type so you just get them out and put in the new ones. most of the expense is doing the work to get the liners our and making sure that everything lines up true (Ie the block itself isnt fubar and its actually worth rebuilding) then getting the bits to rebuild it.

The kicker.

as all the td5's are low kilometer units the usual causes of engine failure result in enough damage to the block to render it un-salvageable so most places just whip the head and the sump of give it the MK I and write it off.

When we start getting some proper high Km units that are starting to suffer then the real value of a rebuild will become apparent BUT I bet that by then someone will be doing reco-exchange units which will pretty much render doing your own rebuilt not cost effective.

Dave, no liners in Td5 they are like a Tdi. There are now oversize pistons available from UK to facilitate rebuilds, before they were avail you would have to bore and sleeve the block, back to standard.

The rebuild costs on these have plumetted due to the availability of good aftermarket parts.

Infact, soon they will be about on par with Tdi for a short rebuild

Isn't this always the case? I think it then it comes down to the quality of parts used in the rebuild as to whether it is worth doing your own or not. Very cheap parts and then it becomes a case of you doing the work, saving on labour to use higher quality parts.

Or am I on dope?

nope thats pretty much the case... but there is a point of diminishing value.

If you're doing the rebuild for the sake of you want to do it then chasing the best parts and a good machinist is always the way to go. with that said.

if you are doing the work as a cost saving measure usually it winds up costing just as much if not more than getting a good rebuilder to do it. And theres the rub finding a reasonably priced rebuilder who doesnt make his profit from using junky parts.

for JC.

Id always assumed that they were wet lined due to the availability of liner kits for them. So a liner job on a td5 is the same as a liner job on a 2.25.

good to know.
