common issues with the 5.3L engine?

Postby jamoka3 [OP] » Dec 18 2011, 5:39am

I stumbled on the Castech cracked head issues that effect the 5.3L, how common is this issue and is there a tell tail sign to determine if you have this issue?
Is there a way to check the engine in the truck, Im going to look at a 05 with 85k miles at a dealer, and I want to check if this is a problem or not?
Its kinda a big deal before i buy this truck...

Well if it's any indication, it has not been discussed very often around here. based in that, I do not think it is common at all.

I just traded in my 2007 Suburban with the 5.3l in it and it had 136000 mile on it. No problem with that motor. I like it so much that I bought a new 2011 Silverado 4x4 Crew cab!
