Question this time on what might be causing a rapid clacking sound under
accelerations around 1500-2000 rpm, especially when engine is hot. I am
beginning to suspect the dump (bypass) valve, since I've now heard that
the valve can open and close rapidly, creating this kind of noise, if
Anyone having any experience of this.
For those who know something about dump valves, what kinds of symptoms
can a faulty valve cause?
