I have another post in here regarding some other problems that I seem to have, but I'll throw this out there as well. 2007 Ford Explorer Limited V8 When the truck is started cold I hear what sound like an exhaust leak emanating on the right side near the manifold. I cannot be sure of that, but it is coming from the right side that's for sure. It is a ticking sound that increases with RPM's and disappears after 10 seconds or so. The sound may also be coming from the right bank of fuel injectors too. I cant be sure if it is a mechanical tick or exhaust leak. It has been doing this for about a year and is not getting worse. It is not a lifter tap either, that I know. Any ideas where to look here? This only happens when the truck is started cold and after warmed up i can shut down and restart with no noise. When warmed up the truck is completely quiet.
