Having problems with your Cars & Trucks ?
2005 chevy 2500hd 6.0 code P0343
\015 This what has happened so far. The rocker arm came apart and was losing the needle bearings. I found this out when I was changing the oil found one stuck to the drain plug. The truck was running fine when I took it apart. These are the parts that I removed valve covers all the rocker arms, Intake, oil pan, timing chain cover. I cleaned all the parts up and reinstalled them. The parts that I put on new was the oil pump, timing chain, knock sensors with a new wiring harness and a new rocker arm in the broke one place. Now my truck is acting like it has a bad miss. I pulled the codes P0102 mass air flow circuit signal low, P0343 CMP cam sensor circuit signal high. The starts up ok just has a bad miss like its not in time. The reason for the oil pump was because the oil pressure would go down slow to 20 Lb and then pick back up to 40Lb this was at idle. I don't know what I could have done wrong unless I got it out of time when I put the new chain on. Thanks for you help Kevin\015
