Eh I just paid $1000 (GM covered approx 50% of cost after I beat them over the head) to have a 2.4L engine rebuilt on a Chevy equinox. The engine had 80,000 miles on it, was just over 3 years old and was completely clapped out. Spun connecting rod bearings (one cracked), timing chain worn beyond spec and 2/4 pistons had stuck rings causing it to burn 4-5 quarts of oil between changes.
This is engine #3 for the car. The first engine went TU after the timing chain broke at 70,000 miles. The replacement engine (installed under warranty) had a 3 year, 100,000 mile warranty and of course I only noticed it was burning oil at 3 years, 2 months (d'oh).
