After the last limp mode break down, it was time to face up to the truth, the inevitable H.G. failure. Well what else would you expect from an engine that has plastic locating dowels 
.
Diagnosing the HGF fault on my TD5 was not so obvious as the usual creaming in the oil as a tell tale sign is apparently quite rare on the TD5's.
I even got a chemical test done to make sure it was the HG which returned a negative result!
So I did what any sane person should do and search Landyzone for the various advices for checking a HGF and sure enough a popular check is to fill up the coolant bottle to the top, run the engine for a little while and wait for the tiny little bubbles to appear. Sure enough they did on mine.
Other indications can be loss of coolant, stiffness of the cooling pipes and a loss of interior heat from the heating matrix.
If you dont want a large garage bill, sell it for spares now! or if you are up for the challenge, DIY! I'm by no means a mechanic but I do like to tinker, so I decided to do the work myself (I like a good challenge).
I'm lucky enough to have a friend whom has an envious large man shed with extras like a ramp and storage for long term tinkering.
The TD5 Haynes Manual was a Christmas present (she can obviously read me like a book, no pun intended), a sure sign that the misuses didnt want the bill either. However it proved to be an invaluable resource for a few things that I needed to reference.
Festivities now firmly out of the way, a week ago I decided (between shifts) to just get on with it.
First I searched the Landyzone forums for tips and short cuts but did not find a decent post on Landyzone however I did on the LRO forum which some Australian has done for a TD5 defender.
Eventually I got the head off and found one of the plastic locating dowels had completely shared in two. Suprisingly there was only a tiny movement but enough to cause problems.
I had the head pressure tested (and would recommend anyone DIYing to do the same) as well as getting it checked to see if it was warped. Luckily mine wasn't cracked but it was slightly warped.
After being machined I sort advice from the specialist regarding HG replacement and opted to increase the thickness from a two hole .500mm to a three hole .650mm which is easily identified on a tab on the HG.
As soon as I've done putting mine back together I might add my two cents in a sort of helpful guide.
I'll keep you posted
