Engine died at 70MPH, won't start

  

silverxj8 -> Engine died at 70MPH, won't start (3/9/2008 7:54:37 AM)

While driving home from work my engine suddenly died.  Here's what happened.  I have a 2004 XJ8 with 44,000 miles.  My office is about a mile from the highway.  I turned the car on and drove to the highway.  I got on the highway, maneuvered past some slow traffic and reached about 70MPH and was holding it when I heard a whoompf sound and the nose of the car dropped.  It was a weird sound - not a thump or a bang, but more like the air rushing out of a tire.  I thought I had a flat so I started driving to the shoulder.  I hit the gas and the car barely responded.  By the time I got to the shoulder the battery light came on and the engine was dead. 

I tried to get it to start and the first two times it barely turned over as if the battery was very low.  After a few tries it started to turn faster but only sputtered roughly and never held an idle.

It's now sitting at the dealer waiting an inspection.

I've searched around but can't find anyone similar to this.

Does anyone have an idea of what it could be?

I'd appreciate the group's insight.

for those of the car dropping.. maybe air shock let go.. air rushing out.. but for the engine  cutting out and how there related together is interesting. ive had the shock thing happen  on a car.

I think the nose dropped due to the engine loosing power.  The suspension didn't feel any different.  I didn't notice the tach until I pulled over but I suspect that the engine had completely shut down at that point.

As soon as I hear from the dealer, I add a new post.

Are the belts good and still on? Maybe the Cats. are plugged!

Bad fuel pump. Bad rem. Could be anything without seeing it. As Brother Genius said, keep us posted please.

Spoke with the dealer.  His first question was asking if I have an extended warranty.   Not a good sign. 

He said they need to tear the engine down to make sure it is what they are thinking, but he believes the timing chain on the number 2 bank broke.  And if it did, he said that isn't good.

I just bought the car three weeks ago and I did take out a Ford ESP extended warranty with it.

I hope this doesn't become a huge fight or hassle.

Has anyone else heard of this happening?  It only has 44,000 miles on it.

never seen it on a newer style XJ.. those engines a pretty much bullet proof..  but anything is possible. the early ones had cylinder head bolts not tight... never seen it
