First 1.9 Punto GT 8V

[PuntoGTturbo]

You can get a 73mm maximum in the x19.. Even the Punto crank is tight in there.

Only cases from the big bore I mentioned.
When you drive without water and you fill on cold water into the hot engine you also can crack the block.
A friend happened this - stupid....

some days ago this happened here by us with an 1.4litre SEB2 PGT

Crack after filling with fresh water?

Only to have all facts, the wall thickness is bigger at the area of the head gasket (for around 10mm height), you can see it easily.
The crack at the shown picture starts in this area. So I don't believe that the bore is the "root cause".

How ever, more information would be nice and helpful, not only pictures of scrapped parts.

I don't want to seem like an ignorant mofo, but isn't this asking too much from the SOHC block? in what concerns internal forces, vibrations, engine torque, etc? wouldn't a custom made block guard do any good here, in preventing further cracks?

[bradleyboy]

That's what we did.
