Engine Rattles and shakes on 1993 Dodge Intrepid

I drive a 1993 Dodge Intrepid ES. The over all car is in good condition. The only major replacements I have done on the car recently is replacing the muffler.

This past summer the engine started to shake and a loud rattling sound occured. I lost almost all the power I was getting from the engine; slow start ups, a great loss in acceleration, shakes alot idling (so much so that the whole car shakes), etc. At first I thought it might be a bad engine mount, I replaced one and still the problem continued.

Then I studied the sound more closely I thought that one of the pistons had colapsed. But after reading through some of the common problems for the Intrepid on this site, I came across this:

"A loose timing chain on early models will produce a rattle (in the front of the engine) because the chain hits the guide. The timing chain should be replaced (the cam sprocket should always be replaced at the same time). Remove and discard the timing chain guide; on later V6 models, the guide has been eliminated."

I just want to be sure if it is the piston that has gone bad or will I need to just replace the timing chain and such.

Over all I want to go into the shop or dealership truely knowing what is wrong with my car so they don't charge me for extra costs that may or may not help out getting my problem fixed.

I bought a 1993 Dodge Intrepid last year when i got my taxes in March...2.7 liter Engine
I went out of town with it that following week-end and it broke down! I called a friend to come get us. After about an hour of time, the car started back up and we turned around to go home...drove just fine all the way there and so on! Kept having the same issues as time went on...a noise started and never could figure out where it was coming from.
To make a long story short..if you have an Intrepid with a 2.7 liter engine, you won't have it for long! They never recalled the engines to this day! I had the car less then a year and the transmission went out on it! If you really look at the reviews on the cars, you'll see that a lot of people lost a lot of money on these cars! I pray to God that you have another type of engine in that car. If you do, then i don't know what else it could be...but i thought i would go ahead and warn you about the transmissions/engines in them cars! I would really like to know what size engine is in your car b/c i'm telling u, you better be prepared to buy another car!

I could be wrong on this, but I believe if you had a severe problem with one of your pistons, the car would not be running as well as it is. It is much more likely that you're experiencing the relatively common problem with the timing chain.
Did you find your answer? Im having a problem with my 96 shaking. same type of engine though.
These cars (2.7L) have a internal water pump that goes out btween 85,000-110,000 and is ran by the timing chain, the pump was suppose to leak through a hole in side of block when pump goes bad but the hole is usually plugged so the bad pump goes un noticed and the bearing dissinegrates allowing timing chain noise and coolant to enter oil. Stop driving immediatly. Those of u w this motor need to change pump b4 it goes out or u risk a blown motor. Go by the mileage and change accordingly. I would change it at 80,000. It is my belief that this is whats blowing these motors.
