97 Miata with 139,000 miles. Engine starts fine. Slight metallic rattle at first start then a consistent rattle like a timing chain flopping around. Idles and revs fine, still a little noise. Go to drive it around the block and it gets to about 3K rpms and it bogs down. Won't go above 15mph in first. Back in the driveway, I remove the oil cap and there is massive crankcase pressure. Feels like sticking your hand over and exhaust pipe. Guy was asking $1500 so I just walked. Other than the engine being really sick, it would have made a decent first car for my daughter.
