P Reg Disco Problem

Hi
I have a P Reg (1997) Landrover Discovery 2.5 TDi.
Having done 175,000 miles in it, it has developed a fault, which I suspect
could be costly to repair, your comments are welcome. Here's the symptoms:

1. Starts OK when hot or cold.
2. Won't rev smoothly when cold.
3. Occasional blue smoke when accelarating. (Not hard accelarating)
4. Signs of oil of fuel leak in engine compartment, although nothing
"fresh".
5. No noticeable changes in fuel consumption.

Engine Oil, Air, Oil and Fuel filters changed religiously every 6,000
miles. Cam Belt every 60,000

Thanks

Adrian Rees

No mention of oil consumption. You have been using an SHPD oil as specified
have you?
Assuming no undue engine wear then a faulty turbo or injectors seem to be
the immediate suspects. My money is on the turbo.

Between oil changes, there is a little consumption, but not much, and
certainly no changes.
The Oil is Magnatec for Diesels.

Apart from Cam Belts, Oil / Filter Changes, one new battery and a water
pump, no other work or service has been done.
I bought the car 2 years ago, last October, and have put 110,000 on it in
that time. This is mostly motorway mileage.
The engine has overheated once. That was last summer on the M5, but I pulled
over and let it cool down, before carrying on. The gauge never went into the
Red, by the way.

Thanks

Adrian Rees

Sounds about par for the course for (even a well-maintained) 175K miles!
Sounds like it's due for an overhaul sometime in the near future - it really
just depends on how bad you want to let it get before you do that. It'll
probably get to 200K, just gradually getting worse. What you do then is a
balancing act between cost of overhaul/exchange engine and the value of the
vehicle.

Overhaul could mean just injectors and cylinder head, or it could be a full
engine-out strip down (in which case an exchange engine might be cheaper).
Take advice on that nearer the time - preferably not from the guy you might
ask to do the work!

Don't bother overhauling it if it isn't significantly worn. Take it to
someone who can diagnose the fault, which is probably relatively trivial
such as injectors or turbo, and get it fixed. It may have another 100,000
miles or more left in it before it needs an overhaul.

Hi Adrian,

I have had exactly this problem on a Disco. Had a slight overheat and then
the same symptoms you suggest. In the end it was the turbo.

So get the turbo checked - not cheap at 500 pounds (UK) to replace but
worthwhile.

I paid half that to get a turbo reconditioned by Turbo Techniques including
collection and re-delivery by courier within a matter of days. Worth looking
them up. They also sent a very professional looking package as a warantee
too. I was well impressed!
