Oh thatâs good to know that youâve been doing a lot of maintanence. However before you do anything else please have a catch can installed ASAP. That small thing alone will help your car a lot in the long run. Either you can ask some performance car shop to add it or itâs a simple 15-20 min DIY.
Other than that yeah the car seems to work fine as compared to before where every single or every other throttle depression led to a loud or slight knock. No knocks now which is satisfactory.
For in depth cleaning tread carefully as this is a fairly new engine in Pakistan and most will experiment on it. However some are pros so they should know what needs to be done. Good luck. Keep us posted whenever you get the engine heads inspected or cleaned.
