Question
I have a 2000 Nissan Xterra. I parked it, went back later to go somewhere and it wouldn't start. I had it towed to local Nissan dealership. They called me back within one hour and told me I needed a new engine. They said the timing belt was broke and it had ruined the engine. Something about the lifters were bent and the cam wouldn't turn????  Of course I was shocked. They want $4600.00 for a used engine with 87,000 miles and $5700.00 for a rebuilt one. I think they are trying to rip me off. I never ran the car as it wouldn't even start. Could the belt breaking cause all of this damage? I tried to reason with them and asked "Couldn't they just put the belt on and then see if it would run OK? They said "Sure if you have $500.00 to waste. They're insisting they're right.Please let me know. Thanks Loyd

Hi Loyd -

Gosh, I wish I was wherever you are. I hate this kind of thing. If it was the timing belt, I could do it for under $200.

Anyway, there are a few things you can check. You did not say whether you had automatic or manual shift, or how many miles you have on your vehicle. This would be important info for the diagnosis.

I find it strange that the belt should shear that way. It usually happens when you are driving under engine load. Anyway, a quick check is to pop the distributor cap off, and crank the engine, just a little to see if the rotor is moving, If it is not, then it is indeed the timing belt. This might be difficult to check if your car is at the repair shop.

In the shop's defense, certain engines when the belt shears, the valves run into the cylinders and damage the valves. I think your is one of them, but I am not sure. Need more info on the car, I.E. engine size, etc. However, this does not necessarily mean a replacement of the engine, simply a valve job, which should run between $1500 to $2000 at best.

If you would like, I want to talk to you about it so you do not get ripped off. Call me if you wish - (808)216-9800

Thanks and hope this helps with a little insight -
