Ok for rebuild you need few of the things.
If you are lucky enough to find liqui moli shop in peshawar. Than buy following products.
1: 10W-40 MOS2.
2: Ceratec 1can
3: Motor Protect 1can.
4: Motor Oil saver 1can.
Pour the engine oil and add all 3 cans in it remember level up the engine oil 3.6 liters and add these treatments ober into the oil.
Oil filter check after first 2000 kms.
Inspect the oil filter after 2k s and replace it. Than you are good to go for 5 k more.
Remember to break in the engine in cvt transmission you had to struggle more than a normal transmission vehicle.
