Can anyone help? 1998 e-class 240. Intermittent knocking sound from around
front nearside (RHD) at idle. Comes and goes. Can also be heard if engine
revved to just above idle but goes then.
Yes, there are jumper tubes on the heads that feed the
lifters.......they blow out a plug and let oil squirt onto the head
inside the valve cover....find which one/s are bad and buy new from the
dealer.. Is your oil pressure low at low idle?
