YES, All engine must have Positive crank case ventilation. That is what PCV stands for.
There is no PCV valve on the 2.2 Liter engine.
No, it does not.
I would say that my 1998 S-10 does not have a PCV valve, at all, anywhere.
The 1998 and newer S10 with the 2.2L engine does not have a serviceable pcv valve.
If that S10 has the 2.2 L engine, it doesn't have a serviceable PCV valve.
it is on the valve cover, usually in the driver side valve cover. If you have a 2.2 L engine, it doesn't have a serviceable PCV valve, it is built into the valve cover.
The PCV valve is in the passenger side valve cover of the engine with a hose leading to the intake.
Passenger side valve cover
Yes. Should be on drivers side up near the top of the engine. Some of the 2.2 engines do not have a serviceable PCV valve.
"Where is the heater controll valve on a 2001 Chevy S-10 controll Valve? "
I have a service manual picture doesnt really explain anything pcv is not really visible. The 2.2 1998 and up had a non-serviceable PCV system built into the valve cover.
There was no 2.8 Liter V6 installed in a 2001 Chevy S10. I posted a link of firing orders that year.
