disco 200tdi head gasket skim ??
bogie:
Well dont know what planet hes on but 3 holes is the thickest,haynes says so and so does landrover (concerning 200),so cant see why 300 are different! Considering this subject is about 200s its best not to cause confusion!
Range Rover Blues:
On the 300 they go 1, 2, 3 and no holes. It says so in my manual.
I don't have a manual for the 200 and I'm not sure there is the same choice.
Skimming the head makes very little difference to combustion chamber size and none to piton to head clearence, though IIRC there is a dimension for the face of the valves to be below the face of the head, which is the onbly reason i can imagine people fit the wrong gasket for.
Using a thicker gasket lowers the CR and lowers efficiency, a worn engine may even struggle to start.
Then again, my LR manual also says you shouldn't ever skim a TDi head (300 manual remember) but I've done it succesfully, as have countless others.
If you bother to measure piston projection you'll prpbably find and engine that would be fine with a 2 hole gakset exept for one piston (or one side of one piston I found last time).

My version of the (genuine L/Rover) 200Tdi engine overhaul manual is word-for-word the same as the 300Tdi manual. 4 thicknesses of gasket, no-holes is the thickest, thickness determined by piston protrusion above block surface. Head skimming is not recommended.

i didnt find the haynes book of lies much use to be fair - lol
yeah i was worried about head gasket size and thought some posts would come out of my mention.
as for the car its running sweat power wise , i will keep an eye on the mpg see if that has changed much .
i had 4 peoples view on this and when the 5th came along with use a thicker one i went that route. might not be the same for others.

The head is back on now and evrything is fine. I had a exprienced friend helping me with it and he asured me it did not need a skim and evryone I showed it to
agreed. I cheked it with a enginers rule just to be on the safe side and it looked fine just gave it a good clean up useing wet and dry and plenty of wd40 and same with the block got both surfaces shiney. as there was no need for a skim I got exactly the same gasket. wether this lasts or not only time will tell I guess. Beleve it or not I quite enjoyed doing this, it gave me chance to see inside the engine and clean all the injectors and heater plugs and all the grime from the top of the heads. it was amazing to here it start 1st time becase I realy did think that engine had had it. I think the only thing we forgot to do was replace the coper compresion washers on the botem of the injecters and one was back firing a little. sorted that out today. I have changed the thermostat just to be on the safe side and have got an oil fillter on standby to change in the next few days.
thanks alot guys
