Injection noice on om606 with myna pump - 350SDL - 09-26-2010
Anybody having any experience with injection noice on om606 with myna pump, the noise is from about 2500 to 3000rpm. on light to medium throttle ( normal highway driving ) it is a " tik - tik" sound almost like a bad valve lifter. can it be caused by wrong ip timing.?

Can you hear the sound when you raise the RPM's and the car is parked?

only a little sometimes. ( depends on the outside temprature, engine temprature.. ect. ) if i drive at 2500 - 3000rpm. with light load the noise i the worst
if i lift the gas pedal the noise is gone, and if i floor it the noise disepear as soon the boost rise.

Kind of like Jeemu's?

yes it is the same, but mine is not so bad...

I believe his is from having very advanced timing to get all the fuel burned 5000-7000rpm. Larger plungers also mean the fuel is injected in a shorter period of time which is like advancing the timing as well. Try backing of your timing 1-2*.

Thanks. I will try to play a little with the IP timing
