I am just learning so please humour me if I'm asking daft questions ! I am looking for some advice on what to do about fluid leak although I am of course fully aware that a 30 year old Landy isn't necessarily going to be leak free. I have had a good look in the engine bay and underneath and there seems to be two leaks going on. One from around the sump gasket and the other from the gearbox. I understand that you can knacker a gasket by over tightening bolts but is there any rule of thumb in terms of tightening up bolts when gaskets are involved? Also, what should I do about leakage from the gearbox?
 
Your leak at the sump could be coming from above. The sump does not have a gasket as such. Use a bead of RTV sealant on it if you remove it and clean both faces before refitting. More likely your transfer box thats leaking.

Thanks very much for posting that photo. So what are the two parts you have circled ? I guess these are common sources of leaks then?
 
The left one is, I think, the intermediate shaft. I pulled the image off google to help you identify where they leak. Mine leaks from there. But they can also leak from the rectangular plate with all the bolts round it. From memory I think some of the bolts go all the through and need some sealant on the threads.
 
It's worth cleaning the area around the leaks really well to help track down where it's coming from. Hot oil can travel quite a distance. If it is a leak from the engine sump gasket, it's worth checking that the bolts are all tight, but they are small bolts and are not supposed to be highly torqued. There is a danger that you could strip the threads, which leaves you in a worse place. A better job would be to drain the oil, remove the sump and replace any existing gasket, many people use a bit of gasket sealant as well. If the leak from the gearbox/transfer box isn't too bad, it may be better to live with it and check the oil levels frequently. Changing the gaskets will be a biggish/heavy job. Depends on your skills and facilities of course.
 
Had another good look underneath at the weekend. Found that one of the bolts on the sump can't be tightened fully ie it's turning but not tightening which suggests that the thread in the block is goosed. Guess this means it would have to be re-threaded. Without a lift / ramp I think this is going to be tricky. Anybody got any bright ideas? Thinking I might just have to live with it.
