The mechanic have open the engine block and confirm some of the valve have been bent, but manage to repair back not so serious. Save me some buck but overall repair cost also not cheap around RM 800++. Lunch time i go to see the status of my car and they done the valve cleaning and doing the assembly back the valve into the block.

Then i go to see my car again when i fetch my wife back from work as she work nearby the workshop, they have almost done the valve and going to assemble back all the parts. They rush to settle and return my car by tomorrow morning, hopefully it won’t give any problem after repaired.
