I OWN a 2004 Ford Ranger Hurricane with mileage of 140,000km.
It has been maintained by Ford since day one.
The vehicle has never been offroad and is well maintained.
About three months ago, I noticed there were oil drops where
the truck was parked.
A mechanic told me the oil leak was from the turbocharger and
that it needed to be replaced.
A friend recommended another mechanic who supposedly
specialises n diesel engines.
After several minutes of diagnosis, I was informed that the
problem was not only with the turbocharger but my engine was
losing compression as well !
I eventually sent it back to Ford for a third opinion and was
told the engine compression was all right but the turbocharger
has a slight whistling noise during pick-up but overall still in
The leak has since been fixed.
However, I noticed that my gas consumption is now on the high
side and that the vehicle does not seem to have as much power as
it used to have.
I have had three different diagnoses and do not know which
one is the right one !
Are there any place or specific tests that can be performed
to determine if it's the turbocharger, engine compression or
both that needs attention ?
Answer : 140,000km is not a lot of mileage for a
diesel engine and I think there is nothing wrong with the engine
I think there is a leak between the turbocharger and the
inlet manifold that is causing the whistling sound and also the
If I am not mistaken, you may also be emitting black smoke
especially on acceleration.
Get someone to check the connecting hoses between the turbo
and the manifold for cracks, and when refitting make sure they
are clamped tight.
Turbo diesels do not run well with leaking hoses, and while
they may run, performance will drop.
