Timing Tensioner problems of the 1998 Dodge Intrepid

I was on vacation for the weekend in canada, on the way back, and all of a sudden heard a loud knocking sound. I pulled over immediately into a hotel parking lot, and the knock was so loud, it sounded like it was going to explode. It is once again a 1998 Dodge Intrepid 2. 7 liter engine, that has gone bad. I have owned it since 2001, and have changed the oil every 3000 miles with synthetic oil. I even had the timing chain and tensioners changed January 2007, because I heard these go bad and ruin the engine. I am a former mechanic, who really takes care of my vehicles. Every mechanic told me in 2001 that these engines are junk, and not to buy it, but I didn't listen to them. Now the car sits in my driveway, and I still owe money on it.

Safety recall regarding the transaxle floor shifter ignition park interlock on the 1998 Dodge Intrepid. The vhicle would not start. The dealer replaced the timing cover, vc cover, main timing chain, tensioner and guides.
