Ahan. Actually they did it in a pakistani way They made a new gaskit with the help of silicon. Check these pics out.
They first put the silicon like this.
After it the they simply fitted the plate back. They waited for one hour to take silicon it's place as a seal or gaskit.
Afterwards they poured oil in it. May be they didnt have the appropriate gaskit of vitz. So they used silicon instead of it
