Might just be a sticky tappet, I always use WYNNS engine flush before every oil change, keeps it spotless, I run this for around 200 miles, not the recommended 10-15 minutes idle, not had a problem in 27 years with this.
My dad just used some on his v8 to cure a noisy tappet, worked within 5 miles.
