Technical 1.2 16v HG material?

[ycming]

Hi peeps,

With the engine code 176B9000, there are 2 material for the HG fibre or multilayer steels.

Anyone know which is standard for the engine?

P.S the reason am posting here is because the punto section is pretty much pointless from past experience ...

Thanks

The 2 sheet metal is thinner than the fibre one, you might be able to see an edge of it sticking out of the engine?

I've used both gaskets, multilayer steel one in chalky, and the fiber one in plumey.

Fiber one in plumey (mk2a punto) seems better for any waterjackets that are starting to get a little big. I just gave this one an extra 90 turn just to be certain .

Either way, both are ok

To tell if you have the multilayer one you should have a tab of metal poking out the back left of the engine below the manifold.

Thanks

Good to hear from both 16ver .

So if both are ok to use, which would you recommend!?? Which you thick will last the longest lol.

Thanks

not sure with fiats, but i've had plenty of experience with the rover k series engines. initially they were manufactured with the fibre HG's then modded and changed for the steel ones.

the steel ones were definatley better than the fibre HG's for them.

IIRC, the Mk1s used the fibre, the Mk2s the steel ones.

I think the Mk2s had a finer finished block surface to accomodate the steel gaskets.

In theory, they'll all last until you let the engine overheat. I'd put my attention elsewhere or go to solid copper (re-useable) ones.

Am changing cos i am suspecting that it is blown just now. Will do a compression test, just want to know which is best.

I'd start from a different place.

If it has gone, find out why. Sort that.

If it's running with the "alternative" ECU, get that remapped: if it's running lean it'll be prone to overheating and det. If it's overadvanced, likewise.

If it's the autotest car, Rallycinq has a nice line in vented bonnets. There's a lot of heat trying to escape from a radiator that's really too small and an engine that's squashed into a tight space.

If the surface of the block is up to it, the metal gaskets give a higher CR, which is a good thing, but only if everything else is optimum.

All covered in ePER, the metal gasket version has a taller block.
If you can find the engine number, that should tell you.

Also, don't know if it applies to the 16v 1.2 Fiat engine, but the 16v Alfa changed to metal gaskets at the change to CF3 spec and if you use the CF3 metal gasket in the CF2 engine the reduced clearance means valves hitting pistons...

I'll get the engine code tonight if someone could check for me on eper?

Thanks

I have opted for the fibre type after speaking to different people with 16v .

Really appreciate for all the info given!

Thanks
