Hello Baleno master! So I have a Baleno 2002 JXL (G13B engine) and I just had the engine rebuilt(new valves, piston rings, head gasket), I have gone through 500km after the rebuild and I am wondering if i should use "engine flush" or some type of oil additive like "Engine Treatment" etc to quiet it down a little bit as it is a little annoying with the noise. Plus, the engine vibrates a little on CNG, on petrol its fine. Also, after the rebuild when i turn on the A/C on CNG it loses power like CRAZY, i have a hard time even making the car to MOVE in first gear but when it is going like on motorway, the AC and power is fine even in Fifth gear!
Plus, I did a little research online and found out that Baleno as they are called Esteem in America were equipped with MAF sensors, EGR valves and also an O2 sensor, neither of which are equipped on my car! those two sensors can make one hell of a difference in a smooth operation of the engine and also mileage so what do i do?? Is it possible to DIY this?? Can i get these sensors and equip my car too??
Help a fella PLEASE
