i parked my truck last night after work fine as can be and go out this morning and its tapping something mean. its a decent tapping and as i rev it up it goes with the rpms. its not the fan shroud and im guessing a gasket now but any help would be great

thanks

didnt really want this to be my first post to the site but sadly it is...

 

Thar she blows!
You may have a spark plug about to blow out if you have the infamous Triton V8.
Check all your plugs to see if they are torqued up. You may find one loose. Tighten the sucker and cross your fingers. You may be just fine for another 5,000 miles or more.
Good luck.

 

yup that was tightened it back up and shes good for now

and your good i just realized i forgot to mention the bomb that went off when i started it but u already knew

thanks
