I've read where your oil filter can cause a ticking noise. Too much engine oil can too.

I don't know that it was a K&N oil filter that was the problem but one Titan owner switched brands and that helped. As long as the oil pressure is OK then it seems to me that the ticking (if caused by the oil filter) is an aesthetic issue, not a real problem.
