    Good to know and no offense taken. Much rather have the experts do the tinkering and I'll just write the check . . . if and when I can afford to.

    Thanks logray. I finally spoke to another mechanic and then looked at it myself to separate what has actually happened and what is conjecture. This is what I know for certain: (1) The left tensioner is only slightly worn at the tip (like someone scrubbed it with steel wool), (2) The "timing notch" where the tensioner was located appeared to be off by 5 degrees or so (to the right). (3) According to the mechanic, the timing jumped when he removed the tensioner. (4) I turned the car on just long enough to back it into my garage and the engine sounds horrible. Based on what I am learning, I can't imagine that the chain guide would have come off because I would have either heard it happen (never heard anything unusual) and the car would immediately be undriveable (which was not the case until the mechanic replaced the tensioner). For a complete car novice, how hard is it to remove the cam covers to get a better look?

    Thanks. These are helpful comments. I'm in the process of getting a second opinion. I may got the Flat 6 route if necessary.

    Question regarding the Carrera 911 996 engine. My car is 2004 911 with about 18,500 miles. The check engine light came on and I've been hearing some light "rattling" on the rear driver's side. I went to an authorized mechanic (not a dealership). He indicated that the guide for the left drive train had been completely worn away, that the left tensioner was shot and when he replaced it and the cam plugs that the chain had actually jumped the timing. He said there was a significant amount of wear on the chain itself and the place where the guide used to be. I purchase the car 5 years ago from a dealership who certified it used. The mechanic said the engine looks like its been driven very hard on a track. I've never tracked it and only redlined it once (very briefly). The mechanic is telling me that my options are (1) he can do a patch job for about $7,000 - basically replace fix the timing, replace the guides and tensioner, (2) take the engine out, take the engine apart to identify the real problem (determine why the chain jumped and the timing is off), or (3) order a replacement engine. He said option (2) will be the most expensive (likely north of $30,000) and that option (3) - replacing the engine, is my best and safest option. Apparently replacement 996 engines cost around $22,000 or so. So my question is: does any of this sound right to anyone?
