Discovery oil leaks

I only bought my Disco last year. Quite pleased to get back to LR
ownership. I had a 72 Range Rover V8 a few years ago. Beat hell out
of it on Salisbury plain on Sunday and still drove it to work on
Monday.

Owned a Shogun before the Disco which was reliable but parts pricey
and the chassis rotted quicker than a fallen apple.

Now, I need help here because I'm thinking of going back to the Jap
stuff. Disco ownership is not good. I got a 94 300 TDI and it's given
me nothing but grief. My latest nightmare is an Oil leak that makes
the Exon Valdez look environmentally friendly. I can see it bubbling
out from behind the timing case cover where it meets the block on the
nearside at the bottom. It runs along the sump and down all over the
transmission and splatters on the front pipe. So, is this the gasket?
Or something more sinister? I replaced the front crankshaft oil seal
but I'm told there is another that is behind the timing cover. True?
I've also replaced the RTV sealant on the sump thinking that to be the
problem.

Anybody had this before? All help gratefully received.

Thanks

Did you replace the REAR main seal too? Sounds like that could be the
trouble.

Well this is it. LR information is that their is indeed another
crankshaft seal accessible by removing the entire timing housing.

Haynes however say remove:-
The front cover.
The crankshaft timing belt cog.
Prise out the old seal.
Replace the O ring at the same time.

And that's it. No mention of a second seal. If you go to most parts
sites they only list one crankshaft oil seal for the front.
