It happens usually if I push the engine harder or it's uphill.Does not have any pinging when it's idling.
Yes actually first I thought it was spark knock,so maybe the timing was retarded.Set the timing right but still got this noise.I always run with full engine oil.
I start to suspect either timing chain guides/tensioners go bad or worn bearings.But anyone of this things will just make me change the engine.This engine is like 230k miles and just not worth putting more money in it unless I have the money to rebuild the whole thing.I have done all kinds of tune up but the noise is still there.Worn engine is the only possibilty I can think of.
The pinging gets worse when it's hot,especially in summer.
