I sprayed PB Blaster on the #3 intake valve but that was useless. I removed the valve spring on the #3 cylinder and pulled the valve up to it tapped the top of the cylinder. I spun it around multiple times to try and get a seal but when I added compressed air into the injector port, the air just blew out the intake port.

Tomorrow I will pull the head and see if I can determine why the valve is letting air get by it.

I was crossing my fingers hoping I didn't have to pull the head but no such luck.

I will update this post when I pull the head.

Thanks for all the help.
