I had to post this because it was quite funny and maybe true. Last week my dads 99 truck had the famous 53 block and sure enough she let go at 89k. The dealer "Dave Smith Moters in Kellog" got the truck back together in a week and 1/2. Now for the funny part my dad has a buddy with a 99 and was asking the mechanic how to find the 53 on the block and the mechanic replied he only needed to check for the number if it was a red truck because all 6 failures they have had at Dave Smiths have been in red 99 trucks. Anyone out there have a different color then red and have a cracked block?
