Lower engine "tink"
Hey everyone, I used the search to check up on this, but it didn't seem like any of the previous threads covered my specific problem.
I picked up an 01 2wd about 3 months ago, and it has the 4.0 SOHC. I have the Airaid CAI and a Flowmaster exhaust (which to my knowledge should put minimal if any added strain on the engine). She has 93700 miles on her, and about a week ago when I started it up to drive to school in the morning I could hear a metal on metal "tink" coming from the engine compartment (I'm 99% positive it's not the trans from the estimated location of the sound and the smoothness of the shifting). It happens at varying RPM's, it does not happen at a specific time interval, and it doesn't happen (to my knowledge) once the truck is warm...
I've already run a complete fuel system cleaner through it, and used a can of "engine restore" which worked well on my last high mileage vehicle. The noise is still present. No power has been lost, but I'm a bit of a perfectionist when it comes to my cars. Please, any ideas will help... Thanks
