Default Oil Leak

Hi folks,
Had my 45000 k service the other day and the mechanic found that my big end seal is leaking (between engine and gearbox). I have followed MM's recommendation to service the car every 15000ks, but it would appear that this philosophy doesn't work for seals like the big end seal. The mechanic (private not MM) had suggested that I service the diesel every 7500ks to avoid such deterioration of seals etc, so starting at the 45k service, I was to follow his suggestion. Now I have to go back to MM (Canberra) to try and get the seal fix under warranty. For a seal like this to fail before 45k is just too rediculous. Wish me luck. Cheers for now.

Rear main shouldn't be leaking at that mileage surely.
Can't work out why the oil change interval would affect the rear main seal.
Most seals these days are spring loaded neoprene, even running in severe hot and dusty conditions they'll last longer than 45 thou.

Mine appeared to be leaking at about 15000 but I was told it was a wax (?) that was used in production dripping down once it got hot. It was wiped clean and doesn't appear to have leaked again. (It never actually dripped).

Default Oil Leak

Thanks Twscoot,
I'll be getting a second opion next week. Chap at work is a ex-mechanic and as volunteered to take a look. I'll keep an open mind then and see if it is wax. Thanks for the info. Regards Filbee

By all means get another opinoin but this has been a fault with this model. I have had mine done twice done twice in 2 years and have done 50,000km. The dealer has told me that they see this more often than not. Have a look at some of the earlier threads in this forum.
Its a failrly big job 2-3 days with the car off the road. It has nothing to do with service intervals, just faulty rear main oil seals.
Also make sure that the dealer washes out any excess oil from the rubber mount that separates the gearbox bell housing and the engine as it can retain oil and if not cleaned will drip oil after it is all reassembled.
This should be a warranty job.

After over a year since I discovered what I thought was an oil leak bewtween the bell housing and gear box, (it never dripped and was probably wax used in production) it seems I now have one.

Car is going in for its 45000km service and I suspect as the leak is not a bad one (no drips on my car park at work) it will need to wait until after Christmas.

For those that have had this job done under warranty, is there anything specific I should be asking of the dealer when I drop it in for an assessment?

Cheers.
Andrew

Here's a photo of the leak (see previous post).
Not bad but it's engine oil. doesn't seem to be coming from anywhere higher up the block either. Seems to be threatening to drip from near the bolt.

I had mine changed when I had the clutch done. Other than that it shouldn't need doing. The CAM seals can go but not usually the main.

why is changing your oil at very frequent intervals going to make your seal fail to leak?

Looks like it is a rear seal. Car will be going back in the new year for a fix. :-(
