I have the castech heads on my truck that are known for getting cracks in them and leaking anitifreeze into the engine. The way it sounds there should of been a recall on these heads, this isn't a normal wear and tear deal. Why should the consumer pay for the cost of replacing something that obviously is a manufacturer defect since more than just one person is complaining. It seems like also that gm has helped a few people and then told others that they can't help.

I went out to leave for a meeting and started my truck. I heard a ticking noise that I had not heard prior to this morning. I opened the hood to investigate the cause of the ticking and discovered on the left bank one of the exhaust manifold bolts was missing the head. I then went around to the right bank and noticed that the exhaust manifold was broken completely about mid way of the manifold. I have owned this vehicle since it was new off the dealership and have had very little issue with it until this issue popped up. I have done some research and discovered that this is a major problem affecting chevrolet and gm vehicles with 8 cylinder engines. This vehicle is used as a daily driver and is not used for commercial towing, nor is it used for towing on a regular basis.
