Hey guys,
I have done a few searches of the forum and there is plenty of info of startup noise in these motors but haven't found much on the sort of noise I am getting in my 2009 d22.
I bought the car in August last year and all was good until about the time of its 80000k service in November.
Since then the motor has been a bit noisier and rough sounding all through the rev range but especially around the 2000-2500rpm range. It makes all the same noises it always has just a louder version. The sound kind of reminds me of an older petrol engine being laboured up a hill, you know the pinging sound, mixed with noisy lifter sound...
I know they're not the quietest diesels around, I just know its gotten noisier progressively since November.
At that service I put in Nulon 15w40 mineral oil (not sure what was in it before), changed fuel and oil filters (had aftermarket brands in it, I changed to genuine Nissan), blocked egr pipe, changed belts (still had original Nissan ones on it) plus all the other items on the 80k service (its a fairly big service that one).
Since that service I gave it a minor service, just oil change etc...
I'm wondering if its the type/brand of oil making it louder? I've noticed a lot of guys using penrite on here, maybe could try that next time.
The other two things I was thinking was checking the timing chain or that the injectors might be getting noisier?
I've put some two stroke oil in the fuel this tank to see if it helps with injector noise and so far after 100k's it hasn't made it quieter but has changed the pitch of the noise a little.
Just to be clear though, I am not getting a startup rattle in mine, it seems to be quite fine at idle, even when starting cold after sitting for a few days. Just noisy while driving...
Any thoughts/ideas?
Thanks heaps
