 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. *tr

 About 1 month after buying a new 2004 silverado it started surging viloently when cold. it is inconsistant, sometimes lasts for blocks. i almost got rear ended last week while tryig to control the truck. gm refuses to do anything, saying there is no diagnosis codes set and they have never heard of silverado`s surging. they class it as a feature and say i need to feather the clutch. feathering the clutch in traffic is a good way to get killed. this has been going on about 4 months now. i believe they know what is wrong and it is happening with more then just my one truck; but they don't want to spend the money to fix it.

 Had two chevy silverados that develop intake and water pump gasket failure on a 4.3 liter engine. both develop coolant leak through the gasket. the latest was in november on my 2004 chevy silverado. upon checking the owners manual in regards to the dexcool coolant it clearly states that this coolant will burn if spill on a hot engine. it that the case then why can it burn it the intake gasket fail and coolant is leaking in the engine. i had a 2000 chevy silverado with intake gasket failure and also a 2004 chevy with gasket failure. both vehicles i had repaired my concern it the gasket failure on these gm products vehicle that no one at chevrolet seems to care. both vehicles gasket failure occurred around the mid 60,000 miles range. i am concern about the failure of these gaskets that causing the coolant to leak. apparently there is a problem with the gasket or the coolant that causing the gasket to fail. i would like someone to check into the problem of the gasket failure on gm products. especially the 4.3 liter engines. i concern that according to the owners manual the dexcool coolant can burn on a hot engine then can it cause a fire on the engine while driving if the intake manifold gaskets and the water pump gasket keeps failing. i had two different year model chevy silverado with 4.3 liter engine, a 2000 and 2004 silverados where both engine got around 65,000 miles and the gaskets failed on both engine. no one can explain how this occurred. but there must be defect in the gasket design or the coolant is causing the problem. *tr

 After the vehicle is warm, one of the injector sleeves begins to leak diesel and oil into the crankcase, causing plumes of white and black smoke to come out of the tail pipe and causes the truck to sputter. a loud sound of a valve flapping violently also is heard. the truck has been to the dealership 4 times. each time, they say that nothing is wrong. one dealer in monterey said that the injectors are from a 2003 model truck and are smaller than the 2004 sleeves, therefore allowing diesel and oil to leak into the crankcase. the dealership has been unwilling to correct the problem in sacramento.*ak
