Thread: D2a TD5 Need advice, when should I replace my head?

Nick,
that's great that your motor's now fine, those Turner heads have a good rep on here. How long did you drive it while you had a leaking head? Yes another opinion may well be warranted. I have used KHOR in Brisbane for many years, they are LR only specialists and they know there stuff.


Discolaw,
I do know M R Automotive out at Redcliffe they have a good rep too. So they put new head bolts in too, interesting.


Maybe I should have the oil tested? As well as have the head bolts done.


I just don't want to damage the rest of the motor. New injectors would come with a new head wouldn't they?

Cheers

Head bolts in Aus $225, can get from UK for approx. $100 go figure.

"I have just had the injector seals, washers and bolts replaced (MR automotive do the bolts as well)"


Does the head have to come off to do this? If so KHOR would have done the head bolts too I imagine.

Don't forget that the injectors are serialised and MUST be put back in the location they came from. If you swap them around the engine won't run (or will run really rough). If you fit new injectors you will need a Nanocom, Testbook or the like to reprogram the ECU with the new injector serial numbers.

I spoke to a mechanic (not mine) and got a Quote today for approx. $6000 complete to replace the head, that was including $3900 for the Turner head and $700 for the other parts etc so approx. $1400 labour/say $90 an hr so 15.5hrs work.


So does 2 days works sound about right?


Of the $4600 above for parts I can buy direct for $2850, so a big saving. The only problem the mechanic said was that he can't guarantee my parts. I have a $1750 buffer if I supply my own parts, fair risk really????

This isn't actually true, rather a myth that continues to be repeated on this and other forums.
It is definitely helpful to replace the injectors in the same position and indeed the injectors are coded for the ECU to "trim".
However, the incorrect codes do not prevent the engine from starting or operating.

The head does not come off for the injector seals or washers to be replaced. The new bolts would have been the ones holding the injectors in place.

Before spending big dollars please please please get a second opinion from a LR specialist . I fear you are planning on spending big money on a new head that may not even be the problem.
