Hi guys I got a 04 to with a shredded timing belt. Mechanics first thought was the fuel pump was bad but it was determined bit was a cam shaft sensor. Then he pulled the timing cover and found the belt shredded. Can any help me with a diagnosis

 

What do you need diagnosed? The timing belt is shredded, time for a top end inspection and rebuild.

 

How many miles out of curiosity?

 

197000

 

Was that original belt? How tensioner is looking? Does all pulleys turn? Does camshafts turn? Don't rotate camshafts too much. Is there a lot of oil on the belt?

I bet the damage was done to the valves, as you probably kept cranking the car trying to start it. With that many miles, take a look for used engines if you want to fix the car.

 

You can find a decent J32A3 for probably less than $1K. (Same as a TB/WP job at the dealer)

Have it installed, but have the TB/WP done while it's out to save trouble down the road.

Make sure to get a pre-2007 J32A3 because the bell housing changed for the 2007 model year.

 

The only thing that just occurred to me is that some mechanic thought it was a fuel pump. If he had the car and cranked the engine he sure heard the engine. If timing belt would be completely broken engine would make a distinctive noise (no compression). Maybe belt was shredded, but not completely broken - more like partially rubbed off. Maybe the engine is fine?

 

I'm just wondering how a timing belt got let go for 197000 miles. Now it will cost you a lot more than a timing belt job to get it fixed. That mechanic kept cranking the engine, rotating the crankshaft, which might have hit the valves up top many more times than necessary.

 

Diagnosis: get a new engine
