It probably means you need the cylinder bored out and oversized pistons put in. In short, you'd probably be better off finding a replacement used motor. But being you live in KSA, that's probably not an option.
I think i am going to leave it as it is because :
we have 1997 Ford Expedition 5.4 v8 doing almost 400,000 km (250,000 mile)
and the car starting making sound like my azera--- cold start knocking---- befor 4 years at 150,000 mile
now the car still going, i hope my azera doing the same
about replacement motor :
yes i can find an used motor, like you in usa
but in ksa-- GM, FORD,chrysler ( GENUINE PARTS ) MUTCH cheaper than usa, because we have no tax at all .......
same thing for hyundai, kia, Toyota,Nissan etc..
some mechanics told me they can rebuilt my ford (engine +gearbox) for 3200$ using only genuine parts
so i going to use my azera until it is breaks down, than i will rebuit the engine
