Look at my earlier post "Presea camshaft lubrication". I had exactly
the same squealing noise problem on my Nissan Presea (this may have a
different model name in the US). Like you, I assumed it was a minor
belt problem, although my attempt to tighten the belt didn't have any
effect. Luckily my wife by chance encountered a mechanic who heard the
noise and told her it was a serious engine problem. I was very
sceptical but he turned out to be right. Removing the valve cover (a 5
minute job) showed the extreme wear occurring on one camshaft, as a
result of inadequate lubrication. I suggest you do this, because
leaving it unattended could have serious consequences. As part of the
repair the mechanic flushed the engine to get rid of all the metal
particles. He also changed over to semi-synthetic oil (10w40).
