Engine runs rough at idle.ck engine light on.
Passenger side exhaust manifold bolts rust and break off on all gm full size trucks. i have 2004 silverado 2500 hd with 61k miles, problem started at 56k miles as a mild tick that went away when engine warmed up and progressed to constant leak when engine was under load , two rear exhaust manifold bolts broke off causing exhaust leak. seems all truck engines have this problem from 1999 -2007. this sounds like a manufacturing defect that should be addressed by gm .
In wyoming, traveling i90 to hyw 16 mountain pass...7 per cent grade....after two miles engine overheated and had to pull over to let engine cool down...had to take another route to bypass mountain. googled duramax overheating and found this was a very common problem on the 2004 duramax diesel..design problem prevented adequate air from entering engine...should have been a recall or at least gm should have offered a solution... *js
The bolts are braking off the exhaust manfolds and the manifolds are leaking and the computer is making the truck go into reduced power. *tr
Exhaust manifold bolts broke on both sides of engine, 6.0 liter engine, resulting in extreme noise, poor gas mileage, service engine light blinking and smell of exhaust entering cab. why isn't this a recall item since so many people are having the same problem with chevy and gm trucks and suv's? the cost of repair by a garage is astronomical and it's impossible to do it ourselves. the truck now has roughly 112,000 miles since we have to use it at times. *tr
