So, I'm still kinda new to the CTD world... I read posts here every once in awhile that refer to the notorious cracked block #53. How do I tell what block I have in my '99? What blocks were bad and which ones are good?

As I've heard, 53's are the only 'bad' ones. Usually right above the oil pan at the front of the engine. Usually on the drivers side, but sometimes show up on the passenger side. If there are no big numbers, just small ones, its a mexican block, generally regarded as the thickest, and least likely to crack.

Thanks guys. Truckman - thats exactly what I wanted. All the info in that link.... I suppose I'll mosey out this evening and crawl under to see what block I have.... Kinda like going to the doctor, not knowing if you have a terminal disease or not....
