1999 chevrolet blazer with a v6 engine had a premature engine failure at 87k miles. A hair line crack was discovered in a cylinder using a dye test. The machinist who inspected the engine believes it was created as the result of the corrosive action of coolant used by gm. Chevrolet showed no interest in inspecting the engine. Without the aforementioned, I investigated myself, and can only conclude that a head bolt was not properly sealed during manufacturing, allowing coolant to penetrate the bolt area around the rear cylinder in question. This condition created a weakening of the cylinder wall over time causing the catastrophic failure. I've been communicating with chevrolet for over two years with no success.

After having driven the vehicle for about 2 hours on interstate roads (constantly monitoring the coolant gauge - standard for any trip I take). I stopped to go to the rest room and when I returned and started the vehicle it made a horrible loud metal banging noise. I moved the vehicle to that if it needed to be towed it would be ready. I checked the coolant gauge and it was at the very end of the hot zone, checked the coolant and found almost no coolant in the reservoir. I had to put water in to get it home (another 3 hours on the road). At no time during that trip did the coolant gauge indicate that the vehicle was overheating. I have changed the oil per the recommendation in the owners manual and have done most of the other recommendations and have had no other major issues with the vehicle. On july 12th I had the manifold intake gasket replaced, oil changed and tires rotated in preparation for the trip.

During maintenance, owner noticed coolant getting dirty. Had it flushed four times. Heater quit working after first flush. Brownish-gray sludge was blocking the heater core. Mechanic stated it was due to a small leak in the intake manifold gasket causing small amounts of dirty air and oil to mix with coolant. Since having gasket replaced, coolant has not gotten dirty again. Vortec engines 1999-2003 were prone to this gasket failure. Dexcool doesn't mix well with dirt or oil.

Dt*: the contact stated an oil leak was noticed and the vehicle was first taken to a service dealer, then to an independent mechanic. The problem was identified as a failed oil cooler line and "o" rings. The line and ring was replaced. The replacement parts were not the issue as much as the engineering causing expensive labor costs for a small part to be replaced. The manufacturer was not contacted.

I had valve noise and took to local dealer to check. Dealer called and told me it needed a valve job. After the valve job dealer told me there was noise in lower part of engine and thought the motor needed to be replaced. This 1999 blazer has 68,000 miles on it. I feel gm should cover part of this expense. Dealer would not help with this.
