Cylinder head kit

JTlandyboy · Apr 17, 2013

So, I have just received my cylinder head Gasket kit in the post. Great! My one problem is ive never done a complete kit before and as there are no instructions or better still an illustration of where everything goes Ive no idea where "some" of the parts go. Obviously you need to be knowledgable?
Now, Im not a complete idiot.... I know the main head gasket, I also know the exaust manifold gasket, and theres another Square gasket that fits on the exaust. I also recognise the valve oil seals and the rocker cover gasket. I can also see 2 thermostat gaskets. What I dont know is the following and if anyone can give me an idea so i make a proper job of this ide appreciate it (Its a Britpart kit by the way) There are 2 metal gaskets (shiny silver) which look like they might be something to do with exhaust ports??
There is a packet containing 1 large rubber O ring and 1 smaller? Also in the same pack are 4 silver rings and 4 copper rings?? The rest is a large pack of gaskets. Can anyone explain what all those are for or is there a nice Cylinder head gasket set diagrame somewhere on the net please. Many thanks!

kit will come with many extra parts you wont need ,as kit covers the many variations over the years ,valve stem seals are different for inlet and exhaust (inlet been smaller diameter and have a garter spring ,exhausts often dont )injectors have one copper and one ridge steel ,steel fits at bottom of hole nozzel sits on it copper half way up , thermostat housing has 2 gaskets one for top housing 1one for head to housing ,both are slightly different internal diameter ,also there is a oring fits in top housing ,just match up what you take off and leave the rest

I'd also research into the britpart kits to see if they are any good, you wouldn't want to have to redo it all again in a month.

I've actually just (accidentally) bought a Britpart set and an Elring head gasket.

I just took them out to compare them. This is not a scientific comparison but here goes:

Both look similar (composite material with pressed on metal bits)
Elring one has a slight patterning to the material which feels smooth and looks perfect
Britpart on is covered in some kind of sticky stuff which has rubbed off or into runs in various places, has lots of creases and marks on the surface and is more bendy.
Both weigh about the same
The one in the blue packet will not be getting used but I might keep it for emergencies!

Should I be smearing the gasket with oil before fitting or do you fit composite ones dry I can never remember...

Which engine is it for?
There is either an o ring or ridged rubber on rocker cover breather.
2nd o ring inside thermostat housing top cover.
square gasket one with two holes on thermostat bypass housing.

Some of these gasket kits are made for petrol and diesel heads on the petrol there is gaskets between the inlet and exhaust manifolds.
Hope that helps.

I'm also having trouble with a head gasket.

I was about to put the head on when I noticed that the fit of the head gasket was such that there was a substantial space between the cylinder edge and the edge of the gasket on the right hand side.

I spoke to the supplier and he assured me it was ok, but I am of the opinion that a void will be created, between the cylinder and the cylinder heard, and carbon will soon form and become a problem during combustion, eg. Pre-ignition etc.

The gasket that came off, was copper and yes there was a gap, but with the new gasket, which is made of some composite material, the gap is more extensive, indeed, there are places where the gap approaches 10-12mm.

What do you guys think..?
