Hhmmm sadly to say; clearly you dont have a choice.Oh the cost breakdown is this:
Overhaul Package as below,
Complete engine overhaul
1. Decarbonized carbon
2.Coolant
3. Wossner racing pistons
4. Timing chain
5. Timing tensioner
6. Timing guide
7. Cylinder head gasket
8. Fly wheel oil seal
9. KennOl endurance 5w40 engine oil+oil filter
Not sure if it worth it. the car still have about 5 years to go and i cant change the car as i got overloan for this car. So need to pay extra $40,000 just to clear the loan with bank
Just repair and pray hard you dont need another overhaul for the next 5 years to go.
