Is that your cooling system sorted now?

Show looked good, decent weather. The Landy looks right with mud all over it!
 
Done anything to check/diagnose it?

I haven't done anything specific yet, no pressure tests or sniff tests etc.

Will get it checked beforehand to confirm before I set about taking it apart!

But i have asked a few people, and the general consensus is that it's the head gasket.

Get some oil off dip stick and put it on some tin foil then hold a lighter/flame/heater under it. If it starts to boil then there's water in the oil. Not a 100% but a quick and easy way to give you some indication. That along with some other tests will give you a clearer picture.
 
As I was going to replace the head gasket, I thought I may as well replace other bits whilst I have the engine in pieces.

I decided I would replace the P gasket and water pump, as well as the usual gaskets when you change the head gasket.

I made a start this evening - parts haven't actually arrived yet.

Most of these pictures are for my reference so I know how it goes back together, but i thought i'd share.

I wanted the car to be level for ease of working on it. Here is my home made platform - I can't use axle stands as the ground is not level.

This meant i needed a chair to reach the engine bay

Still in good working order, i'll keep this as a spare since I've ordered a new one already.

The second bolt hole in from the left has a lot of oil in it - not sure if this is normal?

Bolt came out very oiley.

Thanks for sharing.
Get two of these as well.
land rover discovery 300 tdi brass thermostat radiator plug ... - JGS 4x4
(replaces plastic ones).

Where did your EGT setup from? Are you happy with it?

Cheers

Don't bother. Get a couple of domestic radiator bleed plugs, much better and allows you to bleed with engine hot.
 
I was going to leave the plastic ones in for now as they're both new - I'm worried about the brass ones rounding off the thread in the housing!

The EGT gauge and probe were off of eBay, about 30 quid I believe. But yeah I'm happy with it, gives me a good indication on when to lift off the throttle a bit!

I put the head back on Sunday afternoon.

Cleaned up the head

Took out the rocker shaft so the head would go back in - I put the push rods in a cardboard template to ensure I put them back in the same order.

I'm waiting for an exhaust manifold gasket to arrive in the post, as the I had was damaged in the post.

I also dropped off the rad this evening to be re-cored.

The plan is to finish putting it back together Friday afternoon - as I need the Disco on Saturday and I'm due to go offroading Sunday!

After my last manifold gasket being damaged in the post, they didn't take any chances this time - strapped to a piece of wood!

I went to another military show yesterday - found out the fuel return pipe was leaking so i've bodged it for now.

I saw this monster whilst I was there.

Then today I went off-roading - car is running well now and it's staying nice a cool. The site was a place called "dirty 4x4 addiction" in Canterbury.

Like an idiot I forgot to put the SD card in the camera inside the car - but below is a video of some of the footage we took with our phones.
