Is this anything to worry about?

Morning all,

My Landy hasn't been driven more than 2 miles in the past 10+ years. The oil on the diff casing, is this any to worry about?

Cheers

Will

i wouldn't panic about it as long as there's oil still inside it, i've seen far worse oil stains on daily drivers

what's with the putty on the bolts? is that hiding something?

I think that's just mud! It isn't there now, bit of an old picture.

Just check its for enough oil in it

just had a thought, whip that breather off and make sure it's clear, rattles and you can blow through it and do the same for the front axle

Is there a way to flush the diff and replace the oil with new stuff?

there's a drain plug under the axle to unscrew, the diff should have a filler/level plug in the side of it

simples

Cool, I'll have a go at that at some point next week.

Oily diff case is often caused by a leaking pinion seal where the oil is blown backwards as you drive. Not a problem if the leak is small and the level is topped up but it's easy to replace especially if you can get at it from the top!

Thinking about replacing the gasket and oil seal as everything is accessible at the moment.

Do yourself a favor and do it. Odds are the seal's gone hard (ooo 'eck!) anyway and those idiot paper gaskets are none too good anyway. Do check the axle casing for rot - lord knows how but I had one on an RRC rust through and leak.

My 109 loooks worse than that - of course it ate a ring gear some time in its life and was bodge-welded... and leaks at the weld.

I'll give it a good checking over. It's going to be sanded down to bare metal and painted before the tub goes back on.
