RE: Lower Intake Manifold Leak...Help!!
They fill aiplane tires with nitrogen because it isn't affected by temp changes. I used to maintain fuel tank gauging systems that used a pressure gauge and nitrogen in transmission lines. People fill tires with nitrogen so you don't have to change the pressure in winter and summer, and it doesn't get higher when the tires heat up. When I worked on the fuels systems, the Nitrogen was free for me, and I had the tires in my Volvo filled. I never had to adjust pressure again...

That is way way too much to change the intake. the lower intake is alot like a small block chevy V8. the upper intake is not hard to remove at all. can easily be done in about 25 minutes, 10 if you have done it more than once. lower intake isn't too much harder. once everything is out of the way. just drain the coolant first to minimize the mess. it unbolts just like on an old chevy 350 v8. disconnect the fuel rail and injector wires and other sensors and its pretty easy. I'd try a reputable shop that specializes in european cars. may cost a little bit more than say Firestone and Pep Boys but is definately worth it, because they know wehat other things to look for while performing the repair. these fast food chain versions of mechanic shops usually just blindly perform the repair and don't take the time to really look at your truck while it is apart. Now don't get me wrong there are some pretty good mechanice at some of those shops but hopw do you know who they are, unless you are a mechanic yourself. I hope this helps you some.

Don't mean to bump an old post, but my 02 discovery has a leaking intake manifold gasket as well, with a $1400 estimate from the dealer to fix, so I am looking at doing it myself. I read the above post and searched, but couldn't find the "60k service" things to check while I'm at it. The vehicle is at 85,000 miles.
I was also wondering if anyone has a service manual/parts diagram for the gasket replacement , id anything but the kit is required (ie sealant, etc) and torque values/etc for the bolts.
thanks

Do the intake gasket yourself, I did a couple weeks ago and it was a breeze. I had roughly 13 hours in it and cost me like disco mike says, around 100 bucks. If you get under the truck and see coolant leaking down around the bell housing onto the cross member bar it's the same symptoms I had.. I was going through roughly a litre of fluid every few days of constant driving. Now, I have been checking it every week and she is holding steady now and have not had to add any at all. I am by no means a mechanic but this was something fun to tackle and allows you to learn about your vehicle in a way that most people don't... GO FOR IT, and we are always here to help...
