My dad owns a 96 dodge caravan with the v6 3.0 in it, with 165,000 miles on it. We've only had it for about 6 months. It looks like the engine was replaced because of the scratches on the side of the engine bay, but have no idea when..... Anyway, what the engine does is that it ticks/knocks when the engine is running. It gets a bit louder and faster as the engine rpm is raised. I have engine repair book, and it says it could be the lifters or springs. It also talks about adjusting the valve clearance, could this be the problem? Are they even adjustable? I need help with this, I want to fix the problem before it gets worse. If any1 can please help with advice, suggestions, or comments, it would be really, greatly appreciated. Thanks a hundred times.
