Hi all,
I was wondering if I could call apon your wisdom to help diagnose a strange sound. At first I though it was the hyro lifters, so I pulled them all out and rebleed them by submerging them in oil and putting a small paper clip through the hole, working it up and down until all the air bubbles came out. This doesn't seem to have fixed it.
The engine makes this sound a little on start up and then clears. Then once up to temp the noise comes back. So im guessing as the oil thins with temp or something expands with heat?
I've attached a video to try and show the problem. It sounds like its in the head.
