Pinning liners = Results

Pinning liners = Results
I finally realized the annoying sound coming from my engine had to be a liner(s) moving after the engine became warm. I decided if this was the case- why not try to pin them if the motor is on the way out anyway. I had no other signs of issues (overheating, coolant clean, not using oil, oil clean, oil psi good across temps etc).
Just that annoying knocking..
So... Pin the liners I went. Results:
Engine is quiet now, haven't heard them since. I did not feel like moving the motor mounts so I was able to pin 6 out of 8. It was completed with engine in the truck. Removed starter and dropped exhaust. Word of caution- it is difficult to seat the set screws to the exact depth. Lots of in/out checking. I opted to use thin lock washers on outside to make any extra depth less instead of cutting bolts over and over.
Here is the link I used:

Good luck! In my case it worked

I unfortuantly did not take pictures along the way as I was a mess. (They say a good mechanic doesnt get dirty... I obviously am not one..)
I will get under the truck and snap a pic of the bolt locations and give a visual.
For those that are planning on doing this while in the truck:
-Drain oil
-D/C Battery (Remember radio code)
-Unbolt starter and hang to side. I did not have a heat shield.
-Unbolt exhuast from manifold down to muffler (Y pipe)/ Remove O2's if you want it off totally
-Used a right angle air drill from harbor freight (about 30.00)
-Drilled all cylinders except where motor mounts were. Link above on location of drilling.
-Tapped all holes with gear from link above. Ensure piston TDC on each drill run
-Physically put my hand in cylinder and judged thread depth. I noticed some where deeper than other depending on where it was drilled.
-Found it hard to keep cutting bolts, so used lock washers on outside to make up for depth.
-Applied red Lock tight
-Tightened down bolts/ ensured flush
-Wire tied them together for added protection from falling out
-Use caution as aluminum block is EASY to drill and EASY to mess threads up. On tapping.. use plenty of oil/ screw in about half turns/ screw out 1/4 turn then continue. Mine threaded great.
-While I had exhuast down, changed the tranny filter out also. If you do this you will need to remove the cross member also unless someone has found out a way to giggle the tranny pan out.
Filled everything up and runs like a champ... no noise.
Will attach a pic soon
