hmm engine block crack? I was in an accident involving a massive pothole and about 3,000 worth front end damage: controll arm, strut, rim cracked bad,wheel bearing. think my block could be cracked? my overheating only happens after a really hard run. bout 5 min after the pushing the engine, it overheats and pours coolant into the opverflow bottle. the coolant is cool. think that could be my problem?
