2002 Pontiac Aztek - Long Block Replacement?

[Scott]

We burned our catalytic converter and #3 cylinder on a road trip this weekend. I had to leave the car at a dealer in Vegas and catch a flight to Denver. The dealer said the #3 has zero compression and that best option is to replace the engine ($6000!). I'm thinking of shipping it back to Denver for $500 and changing the engine myself. I found a rebuilt long block for $1500, with a $325 core. I'm not worried about the cat because it's still under warranty.

Question 1: How complex is long block replacement in an Aztek?
Question 2. Is it even worth it?
Question 3. Are there hidden costs I'm not factoring?
Question 4: Are there any specialty tools required for the job?
Question 5: A local engine shop said they could do it for $2800 max. Should I let the pros do it for me?

I'm an aircraft mechanic, so I'm not COMPLETELY lost when it comes to working on engines. I've got a hoist at my disposal and a box full of standard tools.

Your advice is much appreciated.

I suppose it all depends on how much you like the vehicle ..
and what type of life expectency it has left in it after you change the engine ..
(if the vehicle has other issues) or high miles where it will be needing other repairs soon
changing an engine in an aztec is not a simple matter as they usually change out from the underside of the vehicle (by dropping the subframe out with the engine/trans intact)
which is usually beyound the average (at home) mechanics means
having it done would be your best bet after reviewing the overall shape of your vehicle ..
