Hello to all!
I know how the engine pinging sounds, but either my pinging is strange either I am crazy.
I hear this sound for a split second (it sounds like ping or valve chatter) only when I change the gear from 2nd to 3rd and from 3rd to 4th gear (I have an EE90 Japanese Corolla, 2E engine).
I've tried my engine under heavy load - I've tried to go uphill in 3rd gear almost from start and there is no pinging, also on acceleration and under extreme speeding (when pinging should occur) there is no pinging. Only when I release clutch pedal and press gas pedal. And only for a split second. Remember, it does sound like pinging (or valves chatter). Clutch is working fine, no strange sounds, gears are OK... engine is in very good condition...
What is it? Does anybody knows?
Regards to all,
