I got an engine light about beginning of november code was p0430, definition is "catalyst system efficiency bank 2", this could be caused by high engine oil or coolant usage. Knowing this I check my tahoe for coolant leaks, no visible leaks at all, I take the cover off the cylinder head and I find a lot of sludge, now I know where the antifreeze is going. My tahoe is still running but with the engine light on and with a misfire due to the porous cylinder head, don't know how much more is going to last and can't really stop the tahoe because it's a daily driver.

The engine cylinder heads for the 5.3l gm motors built by castech leak coolant into the engine causing engine overheat and internal engine failures. Gm has issued a technical bulletin #060601019b to address the issue and diagnose the issue. Gm will not offer customers any financial help in the replacement of the defective parts. This issue effects the safety of the vehicle and the safety of the persons in and around the vehicle. The fouled engine oil causes the lifters to fail, the oil pressure to drop and the engine to lock up due to lack of lubrication by the fouled oil and the driver has no way of knowing this is happening as there is no external indicators.

Drove vehicle out of town on christmas holiday trip. After being parked overnight starting vehicle next am big cloud of white gray smoke upon start. Coolant low. Refilled coolant and drove home. Now vehicle constantly leaks coolant with no apparent leak under vehicle or in engine compartment. Oil sludges between oil changes. White smoke after a 30 min drive every time. Gm has bulletin out for bad heads installed and the part number and symptoms matched cracked heads on my vehicle. Dealer aware and sees often not only in this vehicle but all 5.3 engines from a certain time span. Dealer states will only fix at cost of consumer even though bulletin is known. This could cause an overheat situation or engine failure at a bad time or worse. Why are they not made to stand behind this when problem is known? A quick search on google will overwhelm a computer with so many accounts of this problem.

The gm 5.3l built between 2002 and 2006 using castek corporation engine heads were incorrectly built per gm and castek. The heads leak engine coolant into the combustion chambers and burns off causing the engine to overheat. Gm has issued a technical bulletin regarding this issue and requests the heads be changed out but at the clients expense. With the loss of coolant and inevitable engine damage this is a safety hazard and should be a recall and replaced at gm cost. Technical bulletin 06-06-01-019b issued 6/12/2007.

2004 tahoe, 79,000 miles. Engine overheated which could have caused fire if I had not noticed and stopped. Gm dealer says overheaing due to crack in cylinder head and confirmed tsb 06-06-01-019b (06/12/2007) applies to vehicle, which admits there is known manufacturing defect in certain cylinder heads which can cause engine coolant to leak internally causing overheating and potential engine failure.

There are multiple reports on internet of same problems by other owners.
