Hi - purchased my 03' this past April with 66,000 miles and good service records. It seemed to be running fine until October, when the engine took a crap on me. Toyota said it was beyond repair and quoted me 13k for a new engine/cat replacement - 8500 for used. I obviously had a local shop give me a second opinion, and they said it wasn't as bad and could be rebuilt. All in all, they had my car off and on for the better part of three months, and I ended up paying them $4200 for labor, cylinder head, rings, head gasket, and a couple other things. My problem is that I just got it back two days ago, and there is a ticking noise coming from the engine, it's getting poorer mileage, doesn't have as much power as I remember, and I might be wrong, but I think my rpm's are up. I had a friend quickly check it out, and he said he's pretty sure it's the valves that need to be adjusted. Does this sound right? Please help!! I'm not too sharp with engine related issues, but this is forcing me to educate myself!
