Head Gasket

[fesuvious]

Can anyone help.
Just been on paddocks website to order a head gasket.
The problem is there are 3 listed !!! How do I know which one I need ?

Also listed is 'Head Gasket set - Does not include head gasket'. Do I need this as well? Would it include the head bolts ?

The Gaskets are 1.3, 1.4 and 1.5 . How do I find out ........

Thanks, fes

The old gasket will have holes in a tab on the edge (known as notches). If you are having the head skimmed, then you may need to go up a notch.
After market head gaskets go to a 'zero notch' gasket, which is the thickets of all.
A head gasket set will have every gasket and seal needed to totally strip the head including the valve stem seals.

Standing on the passenger side, look at where the cylinder head/main block join is and there will be a small tab of gasket sticking out with holes punched in it (I think it's near No.3 injector counting from front).
1 hole - thinnest, 3 hole - thickest plus the no hole super thickness as Les said.
Get the gasket set as well as this will have the manifold and rocker cover gaskets etc etc.
Order the head bolts seperately as they don't come with any of the kits.

Called paddocks - they inform me that the standard gasket is the '3' notch.

Mine was a 3 hole and the new head measured out to a 3 hole too.

Have you had the head off and tested yet? If it's got to be skimmed you should fit the next size up thickness (no hole if it's currently a 3 hole).

thats where 3 pieces of the valve seat decided to have a disco on the piston :shock:  strangely the piston suffered very little damage as i think it happened just as the engine stopped

That's the most wrecked head I've ever seen  :shock:

heads fine - twas just a snapped cambelt.

Gasket has arrived !!!!!! 18 hours from online order to being delivered. Now thats quick ! Especially as I didn't pay for express delivery !

What a load of tosh....
Probably the most common, but not standard.

And you don't have to start changing the gasket thickness if you have the head skimmed.  :shock:

Gasket thickness is entirely down to piston/deck heights, and nothing else!!  :!:

The minute fraction that you have taken off a head when it is skimmed will not make any major impact on compression ratios' etc etc.  Will still be within tolerence.

For some random reason... people think it does!!!

As the discussion about head gaskets crops up more and more (and I have one to do next week), I asked Turner engineering last night on their opinion. I got a reply pretty-much straight away from Frida, and she says that there is no need to use a thicker gasket - even after a head skim.  As Turner engineering is pretty-much the last word in Land Rover engines, I would folow their advice without question. Porny is entirely correct.

I read somewhere that you are supposed to measure the amount the piston is out of the top of the bore at tdc and use a thicker gasket the more the piston sticks out

[Les Henson]

The amount the piston protrudes from the deck will remain the same if you have the head skimmed. The deck is almost never skimmed - it's cast iron and generally doesn't get damaged. If you have reason to suspect the gasket you just removed may not be the right one, then measuring piston protrusion is the way to determine the right gasket to use.

I was just about to chip in on that subject, piston projection it's called and shouold be checked whenever the bottom end is disturbed (it's also a good ised to get it balanced) and that's why therer are different gaskets available, on a diesel the piston all but touches the head, at which point the valves are closed.
