Valve Assembly Fail

[HD Rider]

After getting my old truck running again I had a bit of a tick that sounded like valve train or possible fuel pump. It seemed to go away under load. Keep in mind, I was told when I got this truck that the engine was new so I did not rebuild it. Last night I used a stethoscope and narrowed it down to #6 so I performed exploratory surgery.

On 2 cylinders the valve guides were not seated properly. The clip was installed between the guide and the spring. The intake on #6 was making the noise but the exhaust on #1 was the same. Fixing #6 was easy but the other one has been a bugger. The guide was stuck and didn't want to budge. I finally got it into place and the clip installed properly. Now I just need to get the spring retainer back on.
