Quick update. I forgot who said it, but someone mentioned using a extension for leverage. We put a extension through the cam gear and pulled up and it popped right off! You guys are heroes! Now, we are taking the front engine cover off anyway because it looks like the tensioner has popped out.
We made the wooden piece to hold the chain and tensioner. So, we just simply hit the sprocket off the camshaft, even though the chain is super tight? How do we get it back on after were done? That chain is hard to fight. We've been following the haynes service manual, but the tight cam chain got us.
A friend of mine has a 1984 Nissan 720 2.4L 2WD. Blew the head gasket between cylinder 3 & 4. We read the Haynes service manual, and it made it sounds easy, but we can't do anything at all. The cam chain is insanely tight. How do we get the chain to be loose so we can take the cam sprocket off? We've been trying for 2 days. We are out of all ideas.
