With that being said, I am on my 4th engine. I treat them as disposable and I keep a used spare engine on hand. I buy used engines, run them until they blow up and then swap in another replacement. 2.5L engines are easily found for under $3K (the engine below was $2,750 with 90K miles) and if you swap it in yourself, you can be up and running for $3,500.
My next engine waiting to be swapped in...
