Thanks JWJohnson, My advice would be to get the Valve covers off check every Valve Adjuster and Rocker Arms for any signs of wear or fresh marking like Grinds If you do not see anything and they all look well enough good then have the mechanic
get a Camera Scope to look at every Cylinder and check for Loose Valve Seats on each Valve also a compression test would come very handy include a leak down test during compression test. I got some Questions for you that might point out whats the taping.
What Motor Oil weight are you using ?
What the water Temp look like at full warm up?
When do you hear the Taping ?
Has the truck Over heated in the 6 years? and how many time?
Nice to meet you all, I need some help with my Dodge Truck engine, i am not a mechanic or know hardly anything about engines, need some directions on where I can good information. Valve tapping in engine at start up but quiets down after the engine runs a couple of minutes
