The rocker tubes were cooked out and put back together. Concerned about where which rocker arm is after putting it back together. I had someone do this for me. Waiting on video from this morning to upload.
that actually sounds very familiar. my 359n olds made a similar noise but it was whenever the engine was running. i wanna say i had a noise like that on one of my 62 cutlass but can remember for sure, seems like i remember an intermitant chirp/squeek. you checkes the rod bearings and main bearings correct?
