i have a 2003 4.7 ram and about three weeks ago on the way to work my truck started making a loud taping noise and sure enough on my way home after work the tapping noise got super loud and i lost power. come to find out the timing guide broke and the driver side timing chain came off the cam. when i got it home i took everything down and found every single timing guide broken and a big hole on the top of my oil pump. a few days later i changed all the guides, the chains, oil pump and the cam sprockets and idle gear. i thoroughly went through everything after i replaced everything to make sure all the timing marks lined up. i turned the crank several times to see if i could hear anything because i heard that the 4.7s are easy to bend a valve. i heard nothing. after i put everything back together, put oil and water in it i started it and it was missing real bad but no tapping noise or anything. i got two codes, one for the fuel injector sensor and the intake which i fixed both but after i did that it still is missing real bad but im not getting any codes. is it possible i could have still bent a valve and cant hear anything?
