When you flush and drop the pan, get ready. You will need a new gasket for the oil pickup tube and some RTV for the pan. The thing that sucks is that you have to pull the track rod, steering stabilizer, and sway bar (on the back) to get the pan out. I figured this out after I dropped the pan. The pickup tube won't let the pan drop out. Might also rent a tie rod puller (screw type, not fork) to get the track rod off. You only need to do one side, but I would inspect your tie rod ends (called ball joints on LR's) and replace them while you are down there. I had already done mine, but I did replace the sway bar end links...

If you jack the vehicle up on the chassis and let the front axle hang I didn't need to loosen or remove the sway bar. I did remove the steering damper and the passenger side tie rod end (ball joint) I left the drivers side in and just swung the steering bar out of the way.

Not everybody wants to mess with dropping the oil pan. If his oil pressure is good then all he needs to do is switch to full synthetic and add eight quarts insted of seven and stay off the highway. Then if he were to change it at 2000 miles for the first two times and then go out to 5000 on the third and subsuqent oil changes he would be just fine.
Yes it would take longer than doing it all at once, but not all of use have the money or time to go through all the other hassle.
96se7disco let us all know how it turns out for you.
Whichever way you descide to go, there is no wrong answer as long as your trk is fixed.

Time out. You said add 8 quarts ofoil instead of 7. How many quarts is it supposed to hold normally? 7? I think my manual says 6. I'm not sure though.Thanks.

You NEVER, EVER put 8 quarts of any oil in a Disco unless you plan on blowing out both your front and rear main seals.
I am not sure where you got that information but it is so completely wrong.

Yeah, I thought 8 quarts was incorrect. Thanks Mike, but why would he say 8 quarts? How would that help my purpose? Would it cause me NOT to have LOW oil pressure? But isn't HIGH oil pressure bad too? lol. Thanks.

He was thinking that by adding more, you would still have enough in the pan at high RPM, if it is getting pooled in the heads. When you do this, the level is higher and the pistons start slapping the oil and blowing it out of your seals. I just saw this post, like Mike said, NEVER do that.

Have you tested your oil pressure yet?

Yeah, my point was to add one extra quart so that it wouldnt run low when it was all inside the valve covers and then the oil light wouldnt come on, one extra quart wont hurt anything.
But if his only takes six quarts then two extra would not be good. His is a '96 and mine a '97 and mine takes 7 quarts so I assumed that his took 7 as well.
So I apologize for any mis-understanding.
On that note, why does his take 6 and mine 7? They are the same engine, does mine have a bigger sump for some reason?
