Its a PCV valve in the valve cover, the neck has broken off in the hose, you can get a new pcv valve at most parts stores

The link refers to the 1.6L engine, there is an option for the 1.8L engine also.

It is just pushed into the rubber grommet, if the rubber is petrified due to heat and age it may be hard to remove and may have to be broken and removed in pieces, don't forget to remove the broken neck that may still be in the hose. I would also replace the grommet if it is hardened and brittle.

  • Thank you for the quick response I thought it was more serious. I will buy one ASAP but I'm just curious what will happen if I drive the car like this – Haameem Aziz Apr 4 at 15:11

    It may set a check engine light due to the vacuum leak at the hose. You can plug the hose temporarily. – Moab Apr 4 at 17:18

Positive Crankcase Ventilation (PCV) valve !! The function of the PCV valve is to eliminate emissions from the crankcase and send them to the intake and therefore combust them again in another engine cycle, which makes the engine’s emissions cleaner and more effective.

If you are a diyer, replace the valve yourself, it would cost you around 5-10 dollars, including PCV valve and installation tools cost.

Nevertheless, the labor cost you ask locally, because it might be difficult to remove the old (broken) part from the crank case.

It is never advisable to use the car without the PCV valve. If you drive your car like this, the oil will be consumed more. It might pollute the environment. It is sometimes dangerous to drive because the vacuum leaks may cause misfire when accelerating, the car may response roughly.
