Maybe the bad running and the oil consumption are two separate problems, generally when a diesel burns oil it emits clouds of white smoke, black smoke sounds like it is burning excess diesel. Time to look at the oil in the turbo to intercooler hose, any oil in the injector loom?

compression test on what?Originally Posted by bronson

i replaced the injector loom 18months ago.
i will check my turbo hose as soon as i get a spare minute and report back

Incorrect
White smoke = excessive unburnt fuel
Blue smoke = burnt oil (Usually from worn rings, poor compression, valve stem seals etc)
Black smoke = good combustion - good power but can also show over-fuelling (Such as a remap or chip)
Bronson is on the money - get a compression test done DanDisco and you'll more than likely find you've got poor compression on a few cylinders so need either an engine rebuild or a replacement.
By the way....a run-away is a very rare occurrence. Yes it does happen but an engine has to be in exceptional poor condition and many other factors have to occur before a diesel will start running on its own oil....

I doubt you would...
Once an engine starts running away - you're well advised to do the same
Flying parts hurt!!!

who do you see for a compression test? like an ordinary mechanic or someone more specific?
all seems like doom and gloom. only has 216000km. and runs well.
im pretty sure its black smoke.

[quote=DanDisco2;2419459]A diesel specific workshop would be your best bet although any good quality mechanic should be able to carry out a full compression test on all 5 cylinders. It's not an involved test and will only cost you a few hours of labour.
Don't despair as it's not all doom and gloom, I've known of some engines running the wrong grade oil (Usually either too light or cheap reconstituted oils) getting blow-by and blue smoke and once the correct grade oil was installed, the blue smoke disappeared after a hundred or so K's. Using the wrong grade oil might also answer the ever diminishing oil levels.
216K kms isn't a lot for these engines particularly if they've been well maintained.
Go see your mechanic mate and let him see it running or leave it with him overnight so he can start it cold.
One last thought.....You're in Tassie I see. With the Antarctic weather you are experiencing do you use winter diesel? Some of the symptoms you describe could be down to fuel waxing which will run better as the engine warms.....just something to consider :-)

IMO for the initial start rough running make sure that all the glow plugs are working... also 1l of oil over 10000 Km is not something to be scared of especially if there's some small leak too which occurs only with hot engine.
it's important the oil's quality too

Also just to clear a few things up. Your inj washers, if failed will not allow diesel into the sump unless the o rings are gone as well , it will allow combustion gases into the fuel though.
Get someone to rev the engine when it smokes while you stand at the back of the car and smell if it's an oily or fuel smell
Getting a comp test done if you can find a workshop with a tester is not only a few hours labour but a rocker cover gasket as well as inj seals and washers..... If the compressions were low you would have lots of blow by , just check this by unscrewing oil cap with engine running , I would be surprised if your motor is bad with those kilometers , unless it hasn't been serviced for a long long time , so don't panic just yet.
Check your engine oil level after leaving the engine stopped for at least 20 mins , this allows the oil to return to the same level every time.
You can check axial play in the turbo while you are pulling hoses off to check for excessive oil in the intercooler hoses, sounds like a couple of different issues, if you do take it to a mechanic , make sure they know their way around d2,s.
Cheers
