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?

Is it a ticking, clatter, or a knock? Also, if you have a hole in the piston, you would have no compression in that cylender. Have you checked for compression?

its more of a knock. at idle its almost silent but as you rev the engine it gets louder. using a screw driver to isolate where its coming from i have isolated it to cylinder one or three. i havent run a compression test yet but will post results after doing so.

Let me know what you find. It could even be a wrist pin that is bad.
