Sooo doing the job i do ive been looking at head gaskets today for Rusty, now there are a few options i have being a standard fibre gasket or a multi layered steel one.

At the moment it has a rather poorly fibre gasket that has lasted 2 years and 15000 miles which isnt to brilliant although it has had a tough time with being driven hard and over heated twice.

I have both gaskets on my desk and on the multi layer steel one seems much stronger in the main problem areas compared to the original fibre item that was fitted as standard on these cars.

Having never used a multi layered steel gasket im woundering if people have any experience with one on a FIRE engine? I know they cure the dreaded K Series head gasket issues so surely they should do the same on a FIRE engine.

I have used them on Motorcycle engines, where the original was a fibre gasket and was known to fail under 4k miles. The multi layer metal gasket solved all the problems and would last near enough forever.

I'm not sure if it's the same, but the Spesso gasket has a good reputation - even if it is a wee bit costly.

Is the metal gasket the newer spec Grande Punto jobby?

Interestingly not Pete, Payen list it for the Mk1 Punto 75 so its worth a shot at £15, strange how they only list it for the 75 but as we know the heads are the same across the 8v's.

For me, the biggest destroyer of head gaskets is corrosion. There is always a little evident around the water passages - but to be fair, this is only when looking at failed ones so I suppose it could be a result rather than a cause.

If you're going for a Spesso (I think this will probably apply to other metal HG manufacturers too, but I know it to be the case with Spesso) you need to specify thickness as they do offer variants that are thinner than standard to slightly raise compression. Obviously in some circumstances this can be desirable, in others undesirable. Just something to flag up :idea:

Cheers Helen and Pete, the Payen MLS one i have in front of me is 1.2mm thick and the BGA fibre one is 1.8mm thick.

Im not big on the compression side of things but with Rusty being N/A having a slightly thinner gasket would higher the compression ratio so it would go even better maybe? :?

EDIT: Found this online about Compression Ratio, very good info worth a read

It should do, it's difficult to increase the compression too far with head skimming and thinner gaskets unless you skim well past the stop markers.

Its on the stop markers at the moment Pete but as we all know they go on well below that. Going to take the head off tomorrow night and see whats going on down there :? .

Call me sad but im quite looking forward to striping her down and examining the internals once again :lol:
