Had big oil leak on my 2001 Holden Jackaroo. As this is a complicated Turbo-Diesel, many garages including some specialized in Diesels will reject to work on this. My "standard" garage (it isn't that anymore) had no idea what was leaking, they referred me to another garage, which rejected the Jackaroo and suggested Donnelly or Holden. Here comes the only downside of Donnelly they could look at the car for another 4 days. So went to Holden and got an offer for the High-Pressure Oil pump which would cost approx. $4'000. Went to Donnelly afterwards, they found the problem to be the injector pump which had a couple of cracks. Replaced it and it cost only $1'300. Car runs much better than before (obviously).

Very good explanation of what was going on.
Personal consultation on what costs could be and how to proceed.
Small extras fixed, while waiting for the payment and documents at pick-up.
My new garage for any problems regarding my car.

Approximate cost: $1300
