Message: [QUOTE="webb06, post: 1483604, member: 7680"] Truck came in as a no start after it has been to a local dealer for the same problem over the last 6 months. On IDS sync and ficm sync were not together. Sync would go to YES after 2-3 seconds of cranking but ficm sync would never show until randomly the truck would start and after running ficm sync goes to YES. Didn't run the best and white smoked quite a bit. Ohmed all the wiring, swapped cam and crank sensors, swapped pcm and ficm even though they were new. Finally used a boroscope and looked inside the cam sensor hole and noticed the pin on the camshaft wasn't centered in the hole. Pulled the turbo and hpop off to find the camshaft has excessive endplay. Pulled the trans to find the cam gear is loose on the shaft and moves in and out. Pulled the cam gear off and found there was an indention in the keyway allowing the engine to get out of time and not start. Pulled the cab, heads, and camshaft. Put on a used gear and tacked it on. Put it all back together and it runs like a champ. You can see where the exhaust valves kissed every piston but the customer wasn't up for replacing them so we let it ride. All the valves were seating fine and surprisingly the heads weren't cracked. Here's a few pics to enjoy [IMG]https://uploads.tapatalk-cdn.com/20170824/8949a9524c6cf56843091cbbfa463126.jpg[/IMG][IMG]https://uploads.tapatalk-cdn.com/20170824/9b16e3ef62a65a95be4f201866aaa72f.jpg[/IMG][IMG]https://uploads.tapatalk-cdn.com/20170824/732b5f1f30d7c93cc1dba90db56c6afe.jpg[/IMG][ATTACH=full]173729[/ATTACH][ATTACH=full]173730[/ATTACH][IMG]https://uploads.tapatalk-cdn.com/20170824/ef0fcaf6d50d432c5f0f9ad4fe924d55.jpg[/IMG] Sent from my iPhone using Tapatalk [/QUOTE]
