Any idea why my car blew up with these symptoms.

Mike Davies 4 October 2005 17:19:29
 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.
