Can anybody tell me how easy or hard it is to do a head gasket on a disco 2.5 tdi. i have a basic knowledge of engines and dont want to pay the cost of a garage doing the job.

extremely easy if it's a 200 or very easy if it's a 300 check if the head is damaged and if not just clean it using fine sand paper/ wet n dry on a surface plate just tape paper to surface plate and work in figure of 8 so you wont get any low spots on the head. a decent hire shop will have a surface plate.

ps my 200tdi cost me £18-00 to do because head bolts are reusable

Thanks for your help,

just worried now about rebuild.
how easy are those push rods to seat back in place?
 
Hi
Can anybody help i have just completed my head gasket change.
Is there anything i need to do before starting her back up as im worried the engine will be dry and might cause damage.
also having had the injectors out will i need to purge the fuel system.
 
Unplug the stop solenoid and whirl it over on the starter for 20 sec or so, to get the oil circulating.
TDi's usually start OK without purging the fuel system after that - there might be an initial puff of smoke though.

where is the stop selonoid
 
in the middle of the off-side of yer injun is the injector pump. It has a single wire connected to it - that's yer stop solenoid (my 200 has a white wire - not sure about 300's).
