Default Time to start using additives?

2004 3.2D
290'kms
oil & filter every 5'kms for last 85'kms if not longer.
Penrite Semi syth oil

Starting to smoke quite a bit at idle & noticeable at low revs / speed.

Greyish smoke, smell like a dirty ol diesel.

Wonder if its worth giving it a dose of fuel additive / injector cleaner etc?

Ive never put any in (since 208'kms) & don't want to F something like pump seals etc,

Any thoughts, wondered about these;-

Penrite Injector Cleaner 375ml ADDIC375, says every 2500kms

Penrite Total System Cleaner 375ml ADDTSC375, says every 10000kms.

Injector cleaners are unlikely going to make any difference or fix your smoke issue. Different problem.

There are a few nice YouTube's on the sense and nonsense of system cleaners and the likes, including comparing and borecameras showing combustion chambers etc.
I have no experience with diesels but the smell of old diesel (so fuel) would make it a rich exhaust mix or incomplete burning one would think. White smoke is usually moisture, black smoke is oil burnt. If that's the case, then there are a few possible causes for each.

I wondered if the injectors are fouled causing them to not spray / atomize correctly causing pour combustion at lower revs.

Also my EGR is still in place, maybe this should be taken out or service?

Main trouble is we dont have a proper Diesel garage in town & im not that confident in the Mitsi dealer.

uses a bit of oil between services, say 5-600mls or there about, bit more if we do heavy towing or such.

Is the smoke more black or is more blue?
Black I would think dirty or worn injectors.

Blue I would think worn piston rings.

Hi Haz,

I recently replaced the head on my 05 NP DiD which has done @ 276,000Km's. Prior to my issues, I tried to use the LiquiMoly intake cleaner spray but honestly didn't remove the years of built up crud. You could definitely put some additive through it but the only way would be to remove the intake and clean it properly. I cleaned mine prior to the head replacement and it wasn't too restricted but a decent amount of build up none the less. Do it yourself if possible to keep the cost down and invest in a good quality catch can (provent or flashlube).

defiantly more grey / blue smoke, not the heavy black you often see with diesels.

Any suggestions for info on removing the inlet to clean?

Might give the injector or system cleaner a bash, look at cleaning the inlet first as they are low cost.

In considered the crank breather mod, is there anyway of assessing how much the case is 'breathing' currently to verify if the smoke is from piston / ring wear?
