Hi All,
<<ERATUM : TITLE SHOULD READ PTC not PCT>>
I've been making a study of the PCV system of my 850 for some months now (maybe even years) and have finally worked out where all the hoses are supposed to go.
I am curious to learn of the functional purpose of the PCT valve (that sits on the main air intake pipe near the turbo). Everyone says we must clean it.... but no one explains what it actually does.
The connections to it are as follows:
1. Connects into main air intake.
2. Large oily breather tube which goes around to the front of the block to the top of the oil catch tank
3. Vacuum tube which goes to the left hand side if the intake manifold.
4. Electrical connection
I would assume that the valve opens to allow the blow by fumes back into the intake to be recombusted. But what is the purpose of the electrical control and vacuum tube ??
Can any one explain its workings?
Thanks in advance :
