I had a bent valve for 1 month before it even broke off. It started fine sometimes it ticked real bad and sometimes it was real quite. Its his valves. If it was his "rod bearings" it would knock istead of tic.

what it is i can't say for sure.
what i can tell you is that most if not all nissan engines are interference engines. so a bent valve can cause major damage, get it fixed asap.
to find out if it's a valve do a leak down test.
