Head Gasket

[Neil-yaj396]

I'm getting the parts together for the mechanical restoration of my Coupe at the moment. As I have the pretty rare 1301cc engine in my car getting a new head gasket is proving problematic. I can get a 1297cc gasket but the bore would be out by 1mm; 76.1 v 76.

Could the 1297 gasket be used with 0.5mm on the circumference not presenting a problem? Could it be cut/modified to fit, or is this just a non-starter?

Its the a supplier that 'makes up' gaskets?

Thanks.

Hi Neil

I would imagine you would be fine with the 1297 one. 1mm and tolerances of manufacture should mean you would not notice. Are there any other differences?

I'm not sure that there are any real differences, the 1301 was just to get around the strange engine capacity speed limit rules in Italy at the time and I'm not sure if they actually changed anything. If I find time I'll try to have a look at the parts book details

As above, they apparently added 1mm to the bore.

It looks like it was a maximum of 0.1mm have a look at the attached. I'm assuming that your engine is 828C3? I will check the parts book later

surely they added 1cc not 1mm which is nothing. La Lancia states the bore increased by0.1mm for the 1301 So 0.05mm on the radius. All you have to be careful of is the fire ring does not overlap the cylinder wall- I suspect the early 1300 head gasket will be just fine. My 1978 parts book just lists on head gasket for "1300" #82315350

I had a look at the parts book for pre facelift and the microfiche (more up to date than the corresponding parts book) for facelift cars and in both cases the part number is 82315350.

Thanks everyone. I was going from the handbook, which by the looks of it is wrong...

I'll get the standard gasket ordered.
