Love my Tacoma...BUT...
 This is my 3rd Tacoma and I love the ride and the overall build quality BUT the engine noises drive me absolutely crazy!The best description I can give is that the engine sounds like a wind-up toy.The noises seem to be an exhaust leak of some kind (most noticeable during acceleration) along with a loud valve-tapping sound coming from both the top and bottom areas of the engine (most noticeable at idle).I believe the exhaust sound may be a known faulty manifold problem (?) but I'm not sure about what seems to be the valve-tapping sounds.If anyone has any input whatsoever to the problem and/or fixes, PLEASE post a reply.I'm praying the dealer will be able to find and fix the problems
