The engine has 127k on it. As for the noise, I think it's coming from the bottom end. I couldn't pin point the source, but I didn't try that hard either. I never bothered to drop the oil pan and take a look because I'd already planned on the b18c swap. Also, I left everything intact because it was in "running" condition when I pulled it and I didn't want to do anything to change that. Like I mentioned before, the engine's power seemed to be about normal, but there was definately a lot of noise coming out of it when it was pulled. Let me know if you want any more info, and I'll get it to ya.
