Excessive vacuum?

Hi,

The engine only produces 15 inHg to 22 inHg. You say the PCV is stuck shut. In which direction is it stuck, toward the engine or toward the intake? When you disconnect it, that is when it should stall because it creates a large vacuum leak.

Do me a favor. With the engine running, disconnect the PCV from the valve cover. Place your finger over the end and let me know if there is a vacuum present. If there is, see how much pressure is coming from the opening on the valve cover.

Let me know. Also, you may have a plugged vacuum hose, so check that as well.

Let me know.

Hi,

I'm missing something. When you connect the PCV and it sucks shut, that should eliminate a vacuum leak and the car shouldn't stall. When it is disconnected, the engine is likely to stall.

Is there a chance you could provide a pic of what you are dealing with? Also, when it stalls or is running, are there any strange odors or smoke from the exhaust?

Let me know.

Where is the smoke coming from? Is it the exhaust? If so, what color is the smoke? For example, is it white, dark gray, blue, and so on?

Let me know. Also, I'm asking the site owner to see if he has some ideas. You may see a response from Ken.

Take care,

Joe
