I purchased a used motor from this wrecking yard in July, 2011. They originally told me they had one on site for $750.00. I came in to pay for it and was told that one is gone, they have one in Tucson for $800.00. Even though I felt a little like a bait & switch I paid for the motor, with a promise it was to be delivered Thursday. Friday I finally got a return call saying the motor had a broken timing cover, they were going to replace it and deliver the engine Mon. Tues. the engine showed up. Every sensor was missing or broken, they had removed too many parts. The reason you get a used motor is it is an easy exchange. It was out of a buick and I had an olds, so the electronics plug did not match, had to change the fuel injector system. Once this was done the engine installed and started, discovered a major oil leak. Found out they replaced the timing cover, but REMOVED the oil pan gasket, and DID NOT TELL US.
