Has any one got any experience of changing the head gasket on a TD5 Discovery or what sort of price I would be looking at to get it done?

That is a big and complex engine to strip down! What are the symptoms??

As Dr Dave says, the storm/TD5 engine is quite a complex engine, to strip and rebuild, change headgaskets on, If you damage an injector when taking then out you have to replace all 5, and then have the injectors/brain calibrated for the thing to run. Injectors are £100 a piece. Id have it done by a pro and would not expect much change from about £700-£800 to do.

I have pressure in the header tank just after start up, blowing bubbles.

Its using water.

The heater works when you drive over 60mph, but remains cool at any lower speeds.

I have no oil mixing in the water yet, so am still open to other suggestions, but am drawing a blank with everything keeping pointing me back to the cylinder head.

Yep the does sound like HGF to me, but you could also have a something more serious like a cracked head or cracked block, it's not un comman on this engines.

Correct it could be cracked which in turn still means I would be looking at taking the head off and replacing the head gasket.

Going to check all the water system again to ensure no leaks and the radiator is working correctly, before I commit to it.

A big bottle of K Seal??

 

[loudandproud205]

K-Seal, Barr's radweld, copper filling stuff that will be thrown at it before removing the head LOL.

 

[Dr Dave]

How did you get on in the end?

 

[loudandproud205]

Using the V8 Discovery instead at the min. As I've been flat out with clearing stuff out and work.

Had a brief drive in it thou and the temp doesn't alter regardless of how it's driven. Heater still being random. Not 100% on if its using any water it didn't seem to on the brief drive it had.
