I have heard of putting Nitrogen in tires, but I didn't think anybody actually did it. Reminds me of when I was working in a shop/warehouse, we used to "change the tires from summer to winter air" when things were getting slow.

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

Hi gang,
Having the same leaking coolant as mentioned I decided to take off the plenum and look at the manifold bolts.
All were snug except the rear driver, it wasn't just loose rather was unthreaded around 3/4". - scary! So I tightened it back down and the leak is considerably less ... But still there. So I think I have a bad intake manifold gasket.
I will be doing it next weekend ... Unless someone knows what I may have missed?
A few questions
1. Am I safe to drive it until then?
2. Tips on how to remove the throttle cables? I disconnected the 3 of them from their pulleys but not from their housing. I ended up supporting the entire system by a bungee cord to move it out of the way.... Advice on how to remove it all together?
Thanks,
Richard
Btw I know wrong area, but I have a 1997 D1 ... But as it is the same problem as has been mentioned I thought is risk it!

Driving a vehicle with known coolant leak is something that should be avoided, but if you must, check coolant level every time you start out, morning to work, afternoon return home. Carry some bottled water in car so you can add to it (distilled would be best). Do not trust heat gauge above 50%. Don't make long trip with out precautions to stop perodically and refill coolant.

A pinhole in the block? Or maybe headgaskets?
Anyway man stay away from your dealership. Hell I would change your valley pan for a dozen dunkin donuts.
EDIT: Damn old thread is old.

The only time I have seen nitrogen used in tires is for track racing( import cars) and for street cars that have a TPS system that is computer controlled. The TPS will throw an error light once a 5 lb difference is detected in tire. Depending on tires and driving style, the h2o in regular shop supplied air expands and contracts. The theory is that with nitrogen filled tires, the TPS light will basically never come on unless there is damage or puncture. For someone with an Audi or BMW every time they go to dealer to have the car scanned and reset - they are getting porked $110 bucks. Nitrogen gives them a solution. Costco now uses nitrogen in the cars when installing new tires.
