The problem with the 2.7L V-6 is this: The engine timing belt is hydraulically tensioned based on oil pressure. IF the oil is not changed religiously at or around 3,000 miles the sludge and crap that can build up have been known to clog the tensioner, which then slackens the timing belt and allows the engine to go out of time. Since it is an interference-type engine, going out of time can cause the pistons to hit the valves, leading to total engine destruction. I used to have two valves from a 2.7L which the owner did not maintain sitting on my desk at the Dodge dealership to show people. The valve stems were bent at approximately a 45 degree angle to the valve heads -- from exactly the situation I described above. If you are looking at a used vehicle with a 2.7L engine, it is best to pass unless you know the seller has maintained it properly. I would take a 1996 Intrepid with a 3.3 or 3.5L engine over a 2002 with the 2.7 ANY day of the week.

That problem was resolved in 2002 with a revision to the pcv system. It was determined that hydrocarbons were getting in the oil and reacting with the additives. Since then there have been no issues with sludge buildup. The 2.7 is a better designed engine than either the 3.3 or 3.5, it has a forged crankshaft, 6 bolt mains, aluminium block and heads producing 200 bhp and 188 ft/lbs of torque. All in a smaller, lighter more fuel efficient package.
