I went to the mechanic.
The engine is in need of maintenance. But nothing urgent. The heating problem still needs to be double checked.
Maybe the radiator is chocked, maybe thermostat valve jammed.
About valve seals, rings. They can't figure out unless opened. They suggested me if pistons don't have play, replacing rings and valve seals would do the job.
If pistons are weak aswell. We might consider changing the engine overall.
Maybe il leave the car on Monday. But il see if I can manage a donor car. Because this will take atleast a week.
Else il delay it further.
Btw this car doesn't has a oxygen sensor.
The rear suspension noise and gear noise will get rectified once I leave the car with them.
