New here, I have a 97 Mercury Tracer as my daily driver, while I build my Nissan240sx. At 88k miles I had the valve seat problem, broke a piston in half, and cracked another...harsh. Lurking through the first few pages I saw this was a very common problem, so I just wanted to get a general tally on how many people had this problem, and how many miles the car had on it at the time. This is partially just because i'm curious, but also to prove to my dad that it wasn't because I drive the car too rough. Thanks for your input.
