ticking noise + excessive smoke linked...

[dannyfiveforty]

My 2001 S320 cdi has a ticking noise between 1500 and 2000rpm that is only apparent when the engine is hot.

Also the car plooms out smoke under harsh acceleration.

I have been told by an independant Mercedes specialist that the link between the motor and valves on the manifold (metal rod) may have become disconnected and so the valves remain in the open position causing the excessive smoke and rattling noise...

Do I need a new manifold or can i buy a kit that replaces the rod etc...

Thanks guys, Dan

If your talking about the inport shut off motor and linkage then yes new inlet manifold needed,
no repair kit on the market!!

I would also check that the EGR valve is operating properly, these do seize up and cause plumes of smoke ...
