Castech cylinder heads on 2001 through 2006 5.3L vortec engines are porous and allow antifreeze to seap into the oil. This is a safety concern as it can destroy the engine (oil doesn't lubricate correctly, sludge buildup) and leave someone, at the least, stranded, at the worst, it can cause a huge engine fire. GM has been aware of this since 2007. They issued a bulletin describing the problem and what needs to be done to fix, but no recall. To fix either the cylinder heads need to be replaced ($2500) or the entire engine needs to be replaced ($5500). My vehicle is a 2005 GMC Sierra 1500 sle. Also the problem has been confirmed by a licensed mechanic. The following is a link to the GM issued bulletin. WW2.justanswer.com/uploads/bluegorilla/2008-12-05_142924_coolant_loss_5.3.pdf

Concerning GM 706 castech cylinder heads/GM tsb 06-06-01-019B I have a 2005 GMC Sierra which has slowly been leaking coolant for about 6 months. I have had it looked at and the dealer informed me that I have a 706 castech cylinder head that is notorious for cracking and leaking. The dealer told me there was coolant inside my oil and recommended replacing the engine. As I have begun researching this issue I realize these cylinder heads affect millions of GM vehicles and loyal customers. GM has issued a tsb and are aware of the issue at hand and in my, and many other customers this should have been a recalled item. I am calling on GM to fix this issue/mistake.

Four wheel drive functions intermittently. Replaced switch and transfer motor. Every 6 months four wheel drive becomes inoperative often after a highway run. Costs to repair have exceeded $1000. Conversations with other owners of similar vehicles, including Silverado, experience similar issues.
