Aslaam o alaikum. I drive Honda civic reborn 2007 automatic full option
While on long route from isb to lahore full time on ac, stayed 2 days in lahore again on the route to fsbd I suddenly found voice in engine and at once smell of burning ( smoke from points on tappet) immediately stopped, car was overheated, started car filled water. And reached nearby easily. Next day found there was leakage of collant actually voices were of collant leakage with pressure. One clip was tighten.. But after wards faced same heating, from engine but heat gauge not showing, right now tappet voice with refusal to get pick.. Checked no issues of headgasket so far.. Mechanic suggested radiator service..
Background
Since last one and half year on few long routes I drove mostly was on rest. Two weeks ago there was a check light with no pick that was adjusted by swapping loopies. New battery was replaced 1 week ago.
Please advice
