Hey,

I basically cannot search for this top as I do not know what the problem might be.

Here are the symptoms:

1983 240D 175k (oil changed every 3k and valve adjustment was done 4k miles ago) Car seems perfect except this:

I keep hearing this popping/pinging/ringing noise coming from the engine. It occurs sporatically without having a pattern. It basically starts from 20mph till about 50mph and then it goes away. It only does it as I am accelerating.

It does not affect the performance of my car as far as I am concerned but big problems start from littles ones and that is why I am trying to figure this one out.

Please help.... if you need more info about the problem please post it

Thank You
