Oil leak madness! Disco 1

So I've been poking around the wife's disco 1 3.9. Looks like the huge mess and missing two quarts of oil on my driveway is coming out through a variety of places. Most of it is dripping on the right-hand- side catalytic converter which burns off and makes an awful stench while driving. That appears to be coming from a leaking RH rocker cover (valve cover) gasket? Sound feasible? Somebody said it might be something called a valley gasket? What else on the back, RH side of the engine could be leaking?

Additionally, every flexible portion of all oil lines under the hood is covered in wet oil. It appears to be seeping right through the damn lines!!! This includes the lines to and from the oil cooler, on the RH side next to the oil filter.

Are the lines on the LH side going into the radiator end takes for transmission oil cooling? Those are seeping too.

There are also two unkown oil lines traveling through the RH side of the engine bay, both of which are also seeping. I can't seem to locate these lines in a drawing.

I've been scouring my workshop manuals looking for a single schematic of all the oil lines underhood!! I can't make sense just yet of what line goes where.

So I'm thinking it at least needs new rocker cover gaskets and new oil lines. I think the drain plug is leaking too...probably needs a new copper washer. Anyway, I really need to wash it to be sure, but this is from a quick look-see. What kind of job/cost am I looking at for replacing said items?

YES i know LRs leak oil. It always has. But not this much! A drip every now and then is just fine. But it's pissing oil all over everything. The entire underside of the engine is COVERED in it.

I should also note the front anti-sway bar (stabilizer bar?) is covered in wet oil and much is dripping off from that.

Do these 3.9 efi thingies still have flame traps twixt inlet manifold and engine breathers? If so soak them in meths and set fire to them, then wash and dry them and replace.

If these get blocked the oil finds a way out via the rearmost breather all over the engine.

I really have no idea.

First job is to get the engine thoroughly steam cleaned, and spotlessly clean, then you stand a chance of seeing where the leaks actually originate from.

Get the engine properly cleaned, 'cos only then can you check what's actually leaking. I had thought the same with mine (300 Tdi) that the rocker was leaking ... in the end it was one of the oil cooler pipes, and a diesel leak from the injector leak-off pipes. I reckon oil and diesel was being blown all over the engine bay, covering it all and making me think I had leaks from everything ... oil _always_ finds the seams and joints and follows them, so you think it's leaking from everything.

I had something like this on my Disco 3.9 V8. Things i did:

Check tightness of rocker cover bolts. Mine seemed to work loose over time. Changed gaskets on rocker covers for non cork ones. Power steering pipes from reservior had loose clips. Tighten same. In fact if its got a pipe clip/jubilee clip on it, check it for tightness. Sump bolts were also loose, sump gasket was duff but never got round to changing it.

The valley gasket will also leak. Changed this on my RRC 3.5 over a weekend. But its worth checking that the 2 bolts for the valley gasket are tight. One at front just behind water pump and one is at back, just reachable.

All of the above helped a bit but i still had one leak which i never cured.
