Update: alright so. Overall things are smooth so far. AC performance is top-notch Alhamdolillah. I use the choke system in the morning. It takes about 5-6mins to stabilise.
Cleaned the air filter box and sealed it properly. Painted the air filter box and the tappet cover using ABRO engine enamel.
However, coolant/water loss has increased. It was like 100ml / 50kms but now its 150-200ml/50 kms. I have an exam at the end of this month so have stopped working on the car for the time being. Final polish by the denter is remaining though and the fitting of indicators.
I have an exam at the end of this month so have stopped with car stuff. Will get back with coolant leakage diagnosis immediately after the exam.
