Hard to see in that pic, but it looks like you might be missing a stud?

Thanks - I'll take a look...

I was told that the 2.25L Petrol valve seats are made of steel, not alloy, so it will run ULP without the additive just fine..

You may find a gasket in there, it usually become 'as one' with the top of the pipe or the bottom of the manifold, or gone altogether. It's a tapered ring that fits onto the join. I usually grab a tube of exhaust sealant, undo the 3 small fiddly nuts, (which should be brass by the way, brass doesn't have the ability to sieze up like steel. You will almost certainly break at least 1 stud off the manifold, resulting in removal of the manifold an the application of some direct heat from a gas torch and with some vice grips it should come out. I think that its about a 5/16UNF stud. This is the worst bit of engineering design on the whole car I reckon) Anyway once you have the 2 flanges seperated, get a good layer of the afore mentioned sealant into the join and tighten the bugger back up, EVENLY. Dont over do it with the spanners or you will have to repeat the whole proccess, ask me how I know! If you can get 2 or 3 long socket extensions and the wobbly bit that fits onto the end that the socket fits into, you can do it from underneath the car. The biggest problem is the danger of braking the studs off. 1 you may get away with, 2 its definatly a manifold off job. A bit of Copperslip on the studs does no harm either when you put it back together.just makes it easier to undo next if you have to.

Best of luck

Picked up a rear diff last night, had a couple of questions...

(Thanks to Andrew for already answering a few!)

I have a few nuts that won't come off (Who would have thought - in a Land Rover? ), and need to know if I can just grind them off or if that creates a whole new problem (please see the pic below of the diff itself - the nut at the top won't undo - and the one holding the shaft in, also at the top, which I know I can just slice off if I need to).

Is there anything else I can try?

If I cut off the top nut on the diff, what do I need to do re. replacing the bolt and nut?

Thanks for any help...





PS. Sorry I haven't put up exciting pictures - they'll come soon I promise!

I'm a tad confused as to which ones are giving you greif... Maybe circle the offenders in paint and then upload?

Why the strip down?

Re the nuts on the diff centre
Very carefully split them with a sharp chisel........
