2002 Dodge Dakota rattle in cylinder 1

I have a 2002 dodge dakota, in dec 2009 it developed a top end rattle which I identified as a tensioner. I pulled the valve covers and started the engine for a split second to see which tensioner was giving the problem. Drivers side. I pulled the front cover and installed a entire timing chain kit, tensioner and all. I also put in a new oil pump. After installation I couldnt get the thing to start. After two days of scan tool chase I looked up potential problems for engine swap. Timing gear was for new comp, mine is the jeep truck comp. When I finnaly got the damn thing started it was rattling and lost oil pressure in less than five min. I decided that I must have a bearing problem due to oil pump going out. I drained the oil, dropped pan, and checked all rod bearings and all looked good. Oil turned out to be full of oil. I changed the injectors and still has rattle and is still dumping fuel in oil. Im thinking wrist pin, hole in piston, but honestly I dont know. Any ideas?
