ENGIN NOISE 2.7 ENGINE
2001 Chrysler Sebring • 6 cylinder FWD Automatic • 78,000 miles
I just bought a 2001 Chrysler Sebring convertable with only 78K miles on a 2.7 V6. Drove perfect for about a week, engine was totally quiet and smooth. In the matter of 2 days the engine is now so loud i'm scared to drive it. Sounds like loose bolts rattling around in the engine. Still drives fine and still has power. No engine light on but it is crazy loud. Ideas?

Sorta hard to tell over a computer. Have you looked and listened under the hood? Could be as simple as worn bearings in something that is driven by the serpentine belt or it could be as serious as worn bearings in something that is driven by the timing belt. Some engines have the water pump driven by the back side of the timing belt. Immediate replacement can prevent damage to the valves if it is an "interference" engine which many are today. The noise could also be internal engine damage. Mechanics can often tell approximately what is wrong by the sound. The 2.7L is well-known as the worst engine Chrysler ever came up with as far as needing conscientious oil changes and good quality oil. That's sad because Chrysler has a reputation of building some of the best and toughest engines in the industry.
Also, there has been a lot of trouble in the last few years with the air conditioning compressor clutches falling apart. They can create a lot of noise too. They are built in Japan for Chrysler and other manufacturers.
