low rpm, valves ping.

If I drive my car at low rpm, like in traffics, I get valve pinging. When I start driving it harder, at higher rpm, the pinging disapears. Could this be related to my oil preasure? I read 0,3 in the gauge at iddle until 2k rpm.

Try higher octane gasoline. See if this removes the noise.

If the higher octane gas doesn't work, check your distributor for proper advance and retard. Sometimes the internal springs and/or the vacuum advance will fail causing improper ignition timing and detonation.
