Nissan has a TSB saying to remove the upper timing chain guide. It is tensioned using oil pressure from the engine, so it is probably gunked up inside. I just sprayed penetration oil in it and worked it back and forth, i also did an engine oil flush to help flush out the sludge. I recommend BG hot flush. But yeah just follow the guide its easy.
