head gasket question
i new here,and im doing a HG for a friend on his disCo 2, i just got the heads from the machine shop ,and all my gaskets, and new head bolts from atlantic british. on the driverside head i noticed the head gasket sits on the block and there is a hole (center bottom of the block)that is by the exaust manifold that the gasket doesnt cover,and there is no openings on the bottom of the head for it,what is it for,and should i put some gasket sealing on it,or just leave it?(i cant post a pic my camera is down)
Never ever put sealer on a head gasket for any reason.
Of any type.
That hole may be for an oil circuit on a different model of engine.
As long as the two guide holes line up and you can
see the oil hole in the block - make sure that the oil hole is not obstructed.
There is ONE oil hole in each block where oil pressure goes up thru.
That must line up with a hole in the head gasket and of course with the head.
I would only use Victor Reinz gaskets.
Or Milke - can't remember exact spelling but these are German and OEM.

Victor Reinz is probably better.

i looked at the photos and tried to upload them to show the pics when i first started this thread ,but it didnt work. i noticed on all of the pics it shows the gasket not covering the hole that is on the engine block between the two center cylenders,on the driver side just above the exaust manifold and i guess it is ment to be this way. thanks for the help and replys.cheers to you both
Here is a pic from when I did it.
The one hole in the upper right - matters.
It has copper or brass on the head gasket.
That is the oil hole.
As a rule - if there is a little hole in the block - then the gasket should let it thru.
If you block on of those holes - for oil, you are toast.

yes i understand what these holes are for, i understand the water runns,as well as the oil runs, its not this side , its the other side of the block in the middle , on the bottom ,in between the pistons. the gasket doesnt cover it.when you put the gasket on the block it will be visable that the gasket doesnt cover it, thats why i was asking what is was.
