smoky td42...

just thought i'd update, filled up at a different servo and have much less smoke. still smokes when i give it. also did near on 7000k's of highway driving.

Is it worse with bio-diesel?.
For the k's on the clock a place to start--
New fuel filter, & a set of reco injectors easy R&R at home.

While your in there, replace any old rubber fuel lines between filter n injectors etc is just good maintenance.

bio - diesel will not has not and will never get near it. under no circumstances i will push it home before i use that stuff. seen what it did to a rodeo ... not for me.
filers 2 year old and yeah injectors are 26 years old. so is the pump.

I wouldn't say it's normal..
Mines 525,000 and sure a bit of smoke but by no means a screen
I do find the vortex and ultimate fuels feel and sound far better than regular..

Not saying I condone Bio fuel, and I also try to avoid it if possible.
But the amount of trucks I see fill up with bio is huge, lets face it, kenworth,freight-liner etc engines alone are generally worth more than our trucks so it can't be all that bad.

I've been advised to replace fuel filter each service, so 2 yrs would be my first port of call.

every service seems a bit excessive... every 7000km .... ? seen the results of bio diesel in a rodeo ... pretty much needed a complete new fuel system injectors, pump, etc. not keen on dong that. every 50 000 km. don't know where he got it from could of been home made.

e-10 fuels do the same sort of thing with petrol cars that weren't designed to cope with it. been there done that. not again.

Most premature engine failures 95%+ come from poor maintenance.
I agree every service is alot for a fuel filter, just passing on advise to help emphasize a point, fuel filters are often forgotten or overlooked .
I haven't done it as often as suggested, a low grade fuel like diesel would certainly need a filter change more often than not.
Whats a filter cost compared to a engine.
I recently replaced turbo, fuel filter, injectors at home & can claim this can make a notable difference by them-selves before a pump is refreshed.

bio diesel these days is much better than when it first come out better refinement and they filter it to a higher micron particulate........ i was working for ruttley freight when bio first come out it was winter,the fat from the fryers was not filterd out and it would saliderfy and block up the fuel filters pumps inc'jectors cost them a mint .......long storie is the fuel supplier picked up there game and now it is fine ........ bio is ok ...... e10 that is a whole different ball game

This sounds spot on,
remember reading for home bio kits heated drum blanket was part of a few kits.
And some other "in car" kits / optional extra, for you to be able to run bio include a "heated" pre filter which flowed the bio past a glow plug to heat the fuel.
so a known problem indeed for home brew / poor quality bio fuel.
thats getting off subject.

Smokey= wear n tear & or over rich mixture .
fuel system input is a good place to start.
and honestly injectors and glow plugs are simple as to replace
might be a time to have a compression test done for piece of mind.

Next thing I'm going to check is the Altitude compensation system, if it's there, will also give the 2 stroke a shot.

Hi bloke. How did you go with this?
