I have a '93 Grand Voyager with about 146k miles on it. It's developed a terrible loud engine knock that is progressing. When it started months ago, it was only when the engine got to normal temp but now it's from the time you start it up and getting louder all the time. It sounds like a diesel going down the road. Could it be a rod or maybe an oil pump? It still runs great smooth with no loss of power.
Thanks, syd
