Where is pvc valve located on 1987 toyota celica

Hi

The first thing to check is that the engine cooling fan comes on when you turn on the air conditioning, then you should check the condition of the radiator fins. If they are clogged with debris (dead insects, leaves, etc...) then you will need to get a pressure washer onto it through the front grill and try to blast it clear.

When you switch on the aircon, it puts extra stress on the engine, which causes the fuel economy and engine power to drop, and as a result the engine will naturally run hotter, so it needs a bit of help to cool down in the form of the engine cooling fan.

SOURCE: positive crankcase ventilation system

If built like most, the valve cover will have a fitting with a fairly large hose leading away from it.
The PCV valve (Positive Crankcase Ventilation) is found in this line.

This allows fumes forming within the engine oilways sometimes pushed out by minor blowby of the cylinders to be routed back to the air intake so they combust in the engine instead of being vented into the air, something we didn't worry about 50 years ago.

The PCV (positive crankcase ventilation) valve is the small plastic looking piece inserted into your valve cover it has a rubber hose connected to the end of it.
