I have a leak that I am told is coming from from the rear main engine seal. At this stage the mechanic just wants to keep an eye on it. I know it will be costly to repair but am willing for it to be done. Can anybody think of a reason for mechanics to be reluctant to change it? Surely oil leaks don't repair themselves. Also anyone who has had this done to their 80 series might be able to give me an estimate of cost.
Cheers dougie

Dougie, minor oil leaks can go away but usually do not. It's not a difficult job in a proper workshop. Four hours plus $50 for parts and he will probably want to do an oil change. Wait untill that needs to be done. Mal Try.

Thanks for the reply Mal. Will drop by to the mechanic in 3 weeks and see how it's going.

Dougie,
Oil leaks from gaskets and the like do not go away (normally) but oil leaks from seals such as the rear main and front timing cover do.
The seals are subject to changes in temperatures and most of the time the go away.
I had three vehicles now where the same thing has happened and on all three the leak have gone away by itself.
To repair the rear main oil seal the mechanic needs to remove the gearbox (it is right in between)...
You may have just come across a good trustworthy mechanic...
Trust him and come back to him if the leak persists....
Also check all the engine breathers for blockages...

Thanks for replying Will. Have decided to wait & see. Your suggestion to check breathers is a new one, will further investigate.

I have the same problem on my 75 troopy (170k kms). It is not dripping - more a film at this point. I do not think it will go away as it will be leaking because it is worn, so temperature and state of the oil, viscosity might affect how much it leaks, not whether it leaks. I will be having it replaced before the oil contaminates anything else such as rubber gearbox mounts, clutch etc. I am monitoring it only until my next oil change. Besides, my Toyota dealer needs the money.....apparently
