Hemi tick 2.0

[Dusty]

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

The pad on the rocker arm shafts should never be removed, although there seems to be a 'natural' tendency for some folks to pry them off.

This is the first time I've even heard of the mounting bolts breaking like that! I suspect they were bottomed out and jammed, which could happen if the mounting pad wasn't there. If they were over torqued I would expect the threads to pull out of the head.

By the way, they are three-step torqued: tighten to 7 pounds, then to 23 pounds, then back off 1/2 turn, and retorque to 23 pounds.

" 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."

There is so much jaw activity around oil, oil filters, bad lifters (although this has some validity), camshafts, bad design, etc,. yet folks who work on these engines everyday will mention that a rocker arm can cause a tick.

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.

A piece of welding wire or straightened out coat hanger layed length wise along the head,then lean the pushrods up against it,will work in a pinch to keep them in line.

That wire trick would work. I tried to get some assembly lube on my way home the other night and some guy beat me to the last tube by about 10 minutes, so I used #2 Mystic grease to hold them in place. Also greased the new shaft and rockers with it to avoid a dry start scenario. I realize it's not the best idea, but when life hands you lemons....

That bolt was probably broken by the mechanic who changed the cam and lifters x 2. Came out with a lil luck and a pair of surgery forceps. Luckily. Hard to prove, but it was my first time in there.

First step - find a competent mechanic.

Fun fact...the mechanic is a retired Mopar trained mechanic. You just never know who to trust. That's why I will be doing my own wrenching from now on.

Personally, I would be pretty bothered if I broke a bolt and left it. Even more so because I would definately know that it wasn't right.

I'm sure it could happen anytime. Crap happens, but no reason to leave something you know isn't right.

I love that you did a burnout to test your work! Classy.

 

[Theair98]

Small burnout. TCS limited my fun. A benefit of living in the country. And tires ain't cheap.

Update. Tick is back at idle, driving down the street, cruisin at 55. Only quiets down when MDS active. This makes me think there is a solution. I just don't have it. I realize those lifters bleed when MDS kicks in. So they get quiet. Anyone speculate or know what goes on internally when the lifter should be pumping up? SUPER frustrated. Didn't do this before mechanic replaced the right bank lifters. Shoulda left it alone.
