Diesel Maintenance Tips

Mal 24 April 2005 00:03:17
 Hi



Getting my first diesel (BMW 2.0 Litre unit as fitted to the Rover 75). Are
there any particular things I should make sure are done on an annual
service?



With petrol cars I know about regular oil/filter changes and scheduled cam
belt changes but anything particular things to note with this diesel?



Thanks in advance

Mal

Check and drain water from the fuel filter regularly. Easier said than done
if you have the same damned inconvenient filter unit used by BMW.

You ask specifically for annual chores? Well nothing in particular other
than what is contained in the official service schedule. If you follow this
diligently you will be giving it all the attention needed for a long and
as-trouble-free-as-­possible life.

Regular oil (use diesel-specific oil or synthetic) and filter change is even
more important than petrol engines, as oil has to work harder to keep the
engine clean of contaminants such as soot. If you use your car mainly for
town driving, I'd change more often, some people do it every 6,000 miles.
Also depending on engines, bring forward cambelt change. I tend to alternate
water drainage and fuel filter change, no matter what the manual says. Ditto
with air filter. Also keep an eye on the state of turbo unit, and on any
slits or holes in the rubber hose.

I take my own oil to the dealer (car under warranty) to be used. I've used
Millers XFD fully synthetic diesel oil for years with good results. 5 litres
costs me about £23 which works out cheaper than the dealer charging by the
0.5 litre and I know what oil I'm getting.

Dont use the Rover specified oil, use the BMW one and change it at no more
than every 12,000miles. These engines, certainly when in the 3series (at 150
or 160bhp) are known to lunch turbo's now and then, and its always down to
poor oil and lack of changes (coked bearings / overheating)

Cam Chain on this engine.

I'm curious about this. I'm guessing it's just a Diesel thing, why
does this need doing? Is it because Diesel is thicker than petrol, and
the water doesn't mix in with it, so it just builds up over time?
Having said that I would expect water to go straight through the
filter. How do you drain the water, do you need to dismantle the
filter, or just pull the pipe off it?

I would go along with that but would not worry if the manufacturers interval
was followed with the correct oil. ISTM that Rover have been somewhat lax
about the oil it specifies. This applies equally to Land Rover.

Ruined bearings and turbo seals are much less common on today's water and
oil cooled units which have coolant pumped through them long after the
engine has stopped. Almost without exception any turbo failure can be
attributed to poor driver practice at the start with a cold engine or when
stopping from high revs or suddenly under load.

In reality it doesn't. You are extremely unlikely to get more than a couple
of drops of water in your diesel from one filter change to the next. I ran a
truck for 5 years with a visual sediment bowl/water trap, and it accumulated
about 1/4 inch of water in the bottom of it during that time. If you do get
any water in it, it is heavier than the diesel, so it sits in the bottom of
the filter and goes when the filter gets changed.

Cue ludicrously exaggerated claims along the lines of "I had a diesel for
only 3 weeks and had to empty the water out daily"

Ignore them. Your annual or mileage service will see you right.

Well it's true. But it was a 150KW Genny & some git had filled it from a
barrel that had had the lid left off in the rain.

Back in the real world he's right, acceptable water content in diesel for
road use is very low.

I did but the cause was a leaking filler seal hence when it rained....>

Agreed. You can get aftermarket replacement filters for the German styley
ones that have a screw at the bottom so you can undo it and let it piddle
all thr diesel and oil up your arm if you feel so inclined.>

Sorry, I was thinking of water staying in suspension for an hour after the
tanker delivery, and not settling out in a matter of seconds like normal
water, and about a tank/pump system that doesn't have a filter or water
trap, and about water getting into a fuel pump, which means the filter must
be full of water since the fuel is taken from the top of the filter which in
turn means major major water ingress, which in turn means almost certainly
enough to stop the engine since diesels don't run too well on water, which
in turn would avoid damage to the pump because the water would have to be
replaced by fuel before the engine would run again, and about all this
occurring as commonly as you suggest.

But then I'm an old cynic. :-)­

You wouldn't be if you had seen as many as I have.
Condensation in the vehicle tank can be a problem also but I have seldom
seen enough water accumulate between filter changes for this to be a
problem. Of course some people change filters more often than others ;-)­
Believe it or not, as you like. No skin off my nose one way or another.

So it's good practice to leave it idling for a minute after a long hot run.
And never blip the throttle before switching off-(why do some people do
that?)

I don't know of anyone that does it. Paradoxically some modern diesel
electronic management systems are programmed, by accident or design, to do
exactly this for no apparent reason. Some Cat/Perkins do this.
