Thank You for the response, I use synthetic oil, that is what i was told to use for being a truck that pulls a travel trailer, the water temp looks okay to me the only time I see it go a little over the half way mark is in the summer time when I pull the trailer up a steep incline. I here the tapping when i first start the engine and then goes to a very very low tapping. As long as i owned the truck it has never over heated. I am just worried about blowing up the engine.
Once again THANK YOU for your time helping me with this I do not know where to turn too other then going to a mechanic.
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?
SuperiorStyles I hope you don't mind me posting this question to you, I am new to this forum. I have a 2003 Dodge Ram 1500 with a 4.7 v8, I bought the truck used and have been the owner for 6 years. when i hit about 100,000 mile I started to hear a what i think is a valve tap on start up. the sound does go away after a couple of minutes. Now for the question is this something I should be concerned about and have mechanic look at it. What would be your suggestion on the right rout to follow.
