Well,I entered the 67 Camaro in a car show a few weeks ago. That was the last time I have driven her! It was another week or so till we had weather worthy on the weekend for driving the car (I won't drive it to work, too many idiots). Well, I went to drive her two weekends ago, and the battery was dead. I found the source of that (crappy horn on a Grant steering wheel) and fixed the problem and charged the battery. No big deal. But the real problem came when the battery was charged and I started to crank her. It sounded like the whole motor was coming out!!! Definate metal on metal!!! It sounded like a sledge hammer hitting about a 3 inch diameter steel rod!!! I suspect a dropped lifter, possibly a rod, but I can't really diagnose this. Quite honestly, I am scared to try to crank the car again, for fear of doing more damage to what ever has broken. I have never heard of something like this when the car was running perfectly when I parked it after the car show. It has been a really nice driveway decoration ever since. Now I am finally over being so pissed off at the car, and ready to start to get her back again. I couldn't even talk about it for a week or two. I am at a loss to tell a mechanic what to look for. I don't know a lot about the internals on this particular motor. This isn't a number matching car, and I am going on the seller's word as to the internal componants. I am also going on his word with the milage on the motor. I did check out all the verifiable information, and did have some paperwork but not to the extent as I would document. I do know what I can see, and the car was very quick. From what I can see, this is exactly the way I would have chose to build this motor. I did have it checked out well, and I had good compression on all cylinders, and no leaks. She drives like a dream! I have had absolutly no warning signs of any motor problems. The car has been babied since I bought her, and I have had a ton of mechanical work done. There was problems with the front end, brakes, and some of the other areas. But nothing I didn't expect to find. And I am at the mercy of a good mechanic. And the big issue is that mine may have shown himself as a little less than trustworthy. I'm not going into all the details, but I have trusted him for years and now I have seen a little different side. I don't have the tools, garage or time to look for the problem myself. I want to get an idea of what is wrong before I walk into a shop with an open checkbook. I know none of you can tell me what is wrong with the car and this information is really vague, but I am looking for a starting place to try and diagnose this. Any ideas or thoughts would be greatly appreciated! Yes, I am very frustrated at this point. Thanks to any who can give a little advice.
