2002 Pontiac Aztek - Long Block Replacement?
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.
If you've got tools and a place to do the work, I think you can handle it. Is it worth it? Well, a 7 yr old Aztek isn't worth a lot but if you like the car and the rest of it is in good shape, might as well fix it. Right now it ain't worth $500.
A car of that age will need hoses and other items replaced when you pull the engine. Cooling system, transmission, AC system, etc might need some work while the motor is out. Your potential costs could be higher.
If a shop will warranty the replacement engine and their work, that might be a good choice. Still, is the car worth $3000 with a new motor?
Mechanically, this can be done pretty easily. The real question is financial viability. Good luck with it, whatever you decide.
