Any idea why my car blew up with these symptoms.

Hi All,

I've got an Isuzu Trooper 3.0D Manual, 2001. It basically blew up
yesterday. I was driving along in fourth, around 30 mph. Then all of a
sudden the revs went to maximum and there was a very loud and rapid
clicking noise. Even though I was in gear, the car was just free
wheeling. I turned the engine off straight away but the revs were
still maxed out for around 5 seconds. Rolled to a stop and there was a
huge amount of blue smoke billowing out of the exhaust.

Towed it to a garage and the guy said that there was probably around 3
litres too much oil in the engine.

I had it serviced 2 months ago and haven;t even opened the bonnet
since. There is no way anybody has put any extra oil in it. Could this
oil have leaked in from another subsytem or something. Also would too
much oil cause these symptoms. It was fine up until it went bang.

Any ideas would be appreciated,

Cheers

Maybe some gasoline leaked passed the piston rings into the crankcase (3
litres perhaps) and the blue smoke was from oil leaking past them from the
crankcase. That doesn't explain why it was revving so fast though. Of the
oil had coolant in it I'd think it would be pretty obvious to a garage
mechanic.

Hi Mate,

Just heard back from the garage and you were spot on. The diesel was
leaking into the crankshaft from the injectors.

cheers,

Ideas? Many.

Suggestions? One big one: always check oil levels, and other levels
*every* time you fuel your vehicle. Not doing so can be *expensive*.

back to ideas:

It appears that the transmission failed, the throttle jamed wide open,
and there was too much oil in the engine. No, this is too much of a
coincidence to happen! For all three (OK, just the first two) to
happen at once is quite odd.

Were you driving, or was it your girlfriend, or a friend who borrowed
the truck?

That takes care of one problem. Now read my other reply and give it
some thought. I'm reminded of the Audi 'sudden acceleration' problem
of about 20 years ago. Turns out that they were all driver errors, and
nothing wrong with the vehicle.

One thing that was done was to try to predect the odds of two such
mechanical breakdowns occuring at exactly the same time--the odds were
so high that they were basically never going to happen.

G'day Pete,

The Audi "sudden unintended acceleration" issues in the 80s
were hardly operator errors -- Audi decided to stop blaming
the drivers after a mid-West DMV inspector was injured in an
accident involving an Audi he was inspecting that
accelerated without warning and crashed into a wall.

Audi suffered for over a decade for this debacle -- their
targeted market were upper-middle class and
insinuating/stating that the operators were to blame (i.e.,
"not bright enough to drive these superb vehicles") screwed
them royally in the US market.

One intrepid Audi owner, who happened to be a programmer,
claimed that he was able to isolate the section in the
computer code that was mostly to blame for the issues --
nothing was publicized by Audi after that and many suspected
that the owner/programmer was paid off to keep it hush-hush.

Hello Mike,

Have them check if the diesel fuel was leaking into the
crankcase from the mechanical fuel lift pump -- if the
integrity of the diaphragm in the pump is compromised, the
diesel fuel will leak directly into the crankcase. Diesel
fuel from the injectors will have to pass through the
piston/compression rings indicating that there would not be
enough compression to ignite the diesel fuel, i.e., very
rough running engine.

Absolutely incorrect. Even the NTSB admits that there was no problem
with Audis. BTW, this problem was also prevelant in the MB 190 and
other smaller MB models, too.

The problem (whcih could be called a design error) was that the pedals
were too far left (usually due to clearance with the tunnel) for some
drivers.

Once transmission locks ("Press the brake to get out of parK") became
standard equipment, the problem ceased to be.

As to your "mid-west DMV inspector" cite a reference. Otherwise it is
just FOAF, and not credible.

BTW, this does not imply the drivers were idiots, incompentent, or
anything. After transmission locks became standard equipment there was
one case that I know of where a police car which had been incorrectly
wired (the emergency lights caused the transmission lock to not
engage). An officer at a crime scene got into the car, and did exactly
what this problem does, he hit the gas instead of the brakes, and
tossed it into gear. Two officers died. (sad story).

I've personal experience with suddent acceleration, I"m one of the few
who didn't have an accident, but it was damned close. While in a rest
stop in my MB 190E, I went to back out of a parking space. I put my
foot on the brake, as I should. I had my hand on the shifter just
starting to move it when I realized the engine was revving out of
control. Yes, my foot was on the accelerator. Had I not realized at
that exact time, it would have been fatal for the woman who was
walking past my car at the time. I know she didn't realize how lucky
she was. Scared the living %#$^*& out of me, and from then on I am
*very* careful when I start out.

Yes, I had two Audis, and the MB, with many miles on each.

Ummm, got any real cite for that claim? The DOT disagrees
with you. Something like a verifiable report?

Do you know of any vehicle any where near the power range of
the old Audi that can move the vehicle if someone is truly
pressing on the brakes as the lame-brained drivers all
*claimed* to have been doing? Particularly if the vehicle
is at rest? I know of a very few American brands of an
earlier era that could not stop with the brakes even if the
engine were just idling...but all of them had really big
engines and somewhat crappy brakes unlike the Audi.

Actually it was peabrained folks pretty much unfamiliar with
automobiles.

OOOOHHHHH a conspiracy theory. What kind of computer was
in that Audi? Who made it, and was it a truly programmable
processor or more or less analog? Got a name for that
programmer?
