Indeed. I'm searching online, to find the best price, but how and where do I determine the correct part number/s for the kit I need ?just buy a genuine gasket, the reason it failed again is more important, quality of work and parts on previous change, over heated heads can often fail again if been too over heated previous,cooling system isnt 100%
head gasket which is the vital part is bought separate not in a kit as its choice is dependent on height of pistons and how much skimmed off the head, what was the number of holes on the one fitted as obviously is was thick enough as it was running ok ,youd want a couple of steel dowels if not already fittedIndeed.

What is the purpose of this check, and why might it effect the problems I have had ?given your past problems it might pay you to make a check on the piston protrusion as shown here:
http://workshop-manuals.com/landrover/defendertd5/engine/cylinder_head_gasket_selection/
The test is to get the correct head gasket thickness to maximize compression while avoiding any chance of piston valve or head contact, or even over compression, that's why they have different options of gasket. Its one of these things that is best to have right and may or may not be part of your previous problems but when you do something like this its good to know all of it has been done right, given the cost of the gasket, the new stretch bolts, even the sealant between the head and the cam shaft retainer is expensive.What is the purpose of this check, and why might it effect the problems I have had ?
Fair enough Is there a way of doing this without expensive special tools ?The test is to get the correct head gasket thickness to maximize compression while avoiding any chance of piston valve or head contact, or even over compression, that's why they have different options of gasket.

It may just prove you have the correct gasket anyway which then eliminates something from the list.
its how head gasket thickness needed is measured ,that is with a standard head ,when you skim a head you reduce the depth valve sits from head face ,if this is reduced it will effect head gasket thickness needed too, so you either measure both and select correct gasket or as most do if its just a gasket change and no skimming is going to be done fit what was fitted prior as it obviously was a suitable thickness as engine was running ok with the gasket prior to leakWhat is the purpose of this check, and why might it effect the problems I have had ?
Sweet. Only £15 for the two on Paddocks. Thanks again I'll be back I'm suretheres a threaded hole front rhs of gearbox bell housing you need a special timing pin preferably to lock the crank
theres a pin for cam too but it can be just as well done using a suitably sized drill bit
I have my suspicions that the engineering firm I had it done at last time used plastic dowels as mentioned in the workshop manual. It's the only reason I can think of for it going again after only 2 years.Don't get the head skimmed again. Landrover say you can't skim a TD5 head at all but you can get away with it once if done properly.
AFAIK there is not enough "meat" on the head to skim it twice.
Always replace any nylon locating dowels with steel ones to stop the head walking on the block over time.
It's no more of a big job than on any other engine.
