Spark plug fouling! PCV Valve check?

Featured Replies

Spark plug in cylinder 4 is fouling. Could it be attributable to bad PCV Valve? How do i check and clean PCV Valve? Can you run car with rubber plug replacing PCV Valve to determine fouling cause?

You already have at least two other threads with this issue. Why don't you try sticking with those instead of cluttering up the forum. You won't get any better response this way. Maybe less...

ok. Just soaked it with carb cleaner. Makes ticking noise if shaken and you can blow in one direction.

Done. I guess we are now ready to open and inspect the valve seals. Any video or instruction on how to accomplish this?
