you said black smoke before,
white steam on cold day is normal on all cars, watch your neighbors back out of garage, burning petrol , the product of combustion is H20, or steam.
steam is white, and ends later, hot fully hot engine
white smoke that lingers a long time and smells like burning oil is just that, bad piston rings or bad intake valve seals.
now idle rules
the first fast idle is 15 seconds long max. the idle dash pot device on left rear of throttle body that and ends quickly
leaving this.
cold engine has no RPM rules but is 1000 to 1500 range, the IAC in the base of the throttle body leaks air and races idle .
then the coolant warms up and the IAC closes at 150F (65C) NOW IDLE IS 800, AND STAYS AT 800 AS long as AC is off
"the mechanic also did a reg to valve.
Can a wrong valve regulation cause those problems?" sure.
you mean VALVE ROCKeR GAP LASH?
this must be right and if set too tight , it will burn valves and make ECU go crazy. (vacuum readings bouncing is bad)
or some older Vitaras, head lamps off, blower cab off. and defrost rear glass heater off)
ok CAMI made ,E22 german market VIN.
the engine has coolant overflow tank, tat is 1/2 full of 50% water and antifreeze.
does it drop (discovered) each morning? what I mean do you have to keep adding 50% mix every day or week to this tank
no,good
yes,bad.
