I've just discovered that I have a cracked block! Apparently a previous owner allowed the engine to freeze? I have always parked in a heated garage so I don't know how I could have caused this to happen. Anyhow I am looking at a major repair. If anyone has any suggestions as to the best option, I am all ears. So far the only estimate I have is $7700 for a new block only, using the old parts. Would a short/long block/used engine be a better way to go? Any ideas would be appreciated.
