Thread: New Disco owner, just a quick question?

It looks like the wading plug hole. It's normally left open in case of an oil leak.

Yep, that's the bell housing wading plug, too right as previously said, it is not important to have it in unless you are "motor boating" about in deep mud or water, otherwise best left out in case of rear engine seal or gearbox input shaft oil leakage, and it will not have been the cause of the whirring noise. (Landrover with oil leaks ... Never,... hush my mouth!!)
Check your transfer case oil level, and if it's a manual transmission your gearbox oil level, some vehicles can have significant leaks and start to compromise the safety of bearings/gears etc. There are two entirely separate chambers of oils to check both different types of oil.
If all is ok with that stuff check oils in diffs front and rear then go under the bonnet and check drive belts idler pulleys, PAS pump water pump A/C compressor etc, all of these things have bearings that when not in good health can cause a whirr or whine.

You stated that the noise is there when you change gears. Is it when you press the clutch in?

If it becomes apparent only when the clutch is pressed in is is most likely the clutch release bearing (otherwise known as the throwout bearing).

It is not uncommons for these to need replacing on heaps of different vehicles as they get loaded up every time you change a gear and are generally never serviced because the are inside the bellhousing.

Not really an expensive item but you have to remove the gearbox to replace. Might as well do the clutch and machine the flywheel while you are in there.

Sorry but that cheap part just became an expensive job if you do the clutch etc as well.

If it is the clutch release bearing it should start making the whiring noise as soon as you put a bit of presure on the clutch pedal.

If the noise only happens sometimes it maybe youre spigot bush, this will make a noise mainly cold as it warms it goes away.,

Hope this helps if not give me a call

Thanks for all the replies. I plan on getting it looked over this week some time.

I took it offroad this afternoon and I am slightly underwhelmed, I think it might have just been the tyres on it. Whenever I went near sand it bogged down and got stuck. The only vehicle I can compare it with is a Holden Jackaroo which didnt have such a problem. I am going to get some new tyres over the next few weeks (Any recommendations?).

I also had the transfer case gear stick slip out of low range a few times is that normal?

Thanks

Ash

Did you air down or stay at road pressures?

After selecting low range, stop after a couple of metres & make sure it's fully home.

I did not air down. I was just running at road pressure. I realise i should have dropped the tyres but i did not have a compressor to refill them. I will go out again this weekend and take a compressor with me. I hope it makes all the difference.

What tyres would you recommend, It hasnt had a lift that i am aware of what size tyres will fit without a lift?

On the 1993 Disco, the standard tyre size is 205R16. Later Discos ran 235/70/16 which are slightly wider but the same diameter.

If there's no lift, you should be able to go up to 245/70/16 without trimming. I say should because some cars will just catch the rear 1/4 with 235/70/16s whereas others are fine even with 245/70/16s.

As for the type of tyre, that depends on your driving pattern. Some like HTs, some ATs & other like muds. If you're just doing road driving with a bit of sand, then regular road tyres will suffice.
