besides the rms what else should i be looking at. car is a 97 with about 28k miles on it. Low mileage car. Do the 97s have problems with the ims or slipped sleeves. I use to have a 97 but had more miles than that but was only worried about the rms. Where the IMS / slipped sleeve happening on the 99 up models. Also forgot, which model year had the porousity problems?
