I have a 2000 model 3.0 TD Jackaroo which has just done 40000km. Last Saturday I noticed a few spots of oil on my rear doors. I had a look under the vehicles and was surprised to find a massive amount of oil leaking from the engine area. Too much to locate the main culprit. I immediately took it to Zupps as they have been doing all the servicing on the vehicle since new. They have discovered that it wasn't just one seal which has "let go" but three at this stage of the investigation. They have said that the gearcase seal, Front seal and oil pump gasket have somehow deteriorated and allowed the oil to leak from the engine. They have no idea why this has happened however I am wondering if it could have some link to an incompatability between the oil and the seals. They were initially supplying Castrol XT 10/30 GF2 oil for the engine but after I had a lot of trouble with idle and flat spots during acceleration they changed to Castrol TXT Softec (5W-40) which has worked well ever since although it is quite expensive. Has anybody had these types of problems?

I'm not sure what TXT is, though I have heard that full synthetic lubricants are more prone to oil leaks - this said I use Mobil 1 and have not had leaks

G'Day John,
that certainly sounds a bit alarming. So far no such troubles with my 2000 T/D Jack which has 32K on the clock.
In fact, at the 30K service i had a look underneath when it was on the hoist & was quite surprised to find that it was bone dry - not one trace of an oil leak anywhere.
I was originally using a 15W/40 oil, but have now changed to a 5W/40.
Let us know if you find out any more details.

Well Damien, the saga continues. I went to pick the car up last night after they had replaced the seals, however, according to the service manager, during the test run it began to leak again around the high pressure oil pump. They are now going to replace the pump with a new item because in their opinion it has a 'porous' caseing. They believe that the oil is seeping through the metal body of the pump. Sounds wierd to me but I will keep you posted on the outcome.

My 99 TD 3.0 Jack is on Castrol 10/40 Dynamax full synth......not a leak to be seen....done 58000. ...but you've got us all worried now John. My 90 Mazda Bravo still hasn't had an oil leak anywhere yet.....bloody cars....will ruin us all. Your Jack might have been built early on a Monday, just after a Sunday barbecue in Japan...best of luck with the warranty work...hope it all turns out well......dp

After 55000k in my 2001td auto Jack no leaks. I have always used castrol
TXT which i buy at Kmart when 15% special is on. I provide this to the dealer in Brisbane for the service saving about $45. Dealers price for 7 litres txt $99 Kmart $54. I once had a service in Ballarat ,$140 for theShell oil i dont know what type. After driving on dirt roads a small amount of dust could been seen inside around the cargo doors so they replaced the door seals.
