Hello all. New to this forum. Keep it short. Bought 2012 Ram Sport. Had bad cam/lifter. Had them replaced. 20,000 later, more noise. Replaced lifters. Retainers had come off of 2 of them. 10 times louder! Another set goes in. Not as noisy. Went on 1100 mile trip. Still noisy. Tore valve cover off and found my mechanic had broken the pad that the bolt goes thru to secure the rocker shaft. Replaced it with 3 washers, one of which was slightly bent to match the shaft. Also found the next bolt forward snapped off when I tried to loosen it. I have 4 new shafts and pushrods coming. Never worked on this type of motor before. Am I on the right track, here?

One more question....if that mounting pad is missing, would that affect the oil distribution in that shaft? My mind says the oil will flow out and around the bolt and washers my former mechanic put in place of the broken pad. That would reduce the pressure in the shaft and cause problems. Sound about right?

Pushrods by far are the number one reason why cam/lifter jobs fail, usually means they weren't cupped right in install. Read this thread... Literally happens all of the time, you are on the right track.

Here's a couple photos of what I found. Looks like I'll have 9 exta mounting pads when I'm done.

Lets have a pic of this broken mounting pad you're talking about.If it's the aluminium pad that the rocker shaft bolts to on the head,you might be looking at a new head,as they're pretty critical

I'm pretty sure I am using the wrong term for the broken part. It it the square piece that sits on top of the shaft and the bolt goes thru it. I also noticd in my pic that the wear pattern is overlapped by the washers, meaning there was either contact with the rocker, and or a geometry alignment with that rocker.

Ok, update time. Replaced 4 rocker shafts with new ones. Reused my pushrods as one of the new ones I ordered was missing the ball end. Put it all back together with no pocket pieces, and it actually started and ran. It was my first dive into this motor. On start up, slight tick which had subsided a great deal after a much needed burnout. Small, but fun. I just ordered some Lubeguard after reading a few posts. I can't back it up 100%, but I replicated my tick by sliding the rockers against the mounting blocks that hold things down. It was the same sound I have been hearing. I will give it a few hundred miles and do another update. Thanks to all for their input on this site. Tons of great knowledge here.

There is a factory tool called a Push Rod Support that holds them in place so this issue can't happen. I'm guessing most independent garages and driveway folks don't have one.
