I've got a very random tapping noise. To me it sounds like rockers tapping. It happened before and I could hear it against a drive through wall but went away. Has 113k miles. Noticed a hole in the intake pipe (CAI) a few months ago and patched it. Oil report showed a little higher than average aluminum wear (piston..rings?) and higher than the universal average for silicon (dirt) but they didn't see anything exceptionally high.
Well today my girlfriend said she heard a thud then it started to tap loud. Not like a ball in a rattle can, but almost like an exhaust leak or rockers again. I turned the car off and restarted and it went away. I drove it slowly home (less than mile) and could hear it while sitting at the redlight, and when I got in the driveway it was gone.
Oil has 4,000 miles on it and only use Ford 5w-20 and has plenty of oil. What could it be?
