4.7 WJ Exhaust Manifold Leak?
Hey guys. Over the past year or so on startup ive been getting a ticking that lasts about 30 seconds. However over the last month its gotten a lot worse. it sounds like its coming from the valve train however from what ive been reading it doesnt make sense that it would be the lash adjusters. Because now after it gets fully warmed up and ran for a while it starts ticking slightly again. not very loud but noticeable if your next to the car or open the door and listen under the car.
So when it starts its quite loud and quickly starts fading away. After running for a min its completely silent and nothing sounds weird, but after running a little harder it starts ticking again. which i assume is the manifold expanding enough to start leaking again.
just thought id see what you guys think.
Btw, there is no power loss and gas mileage is normal, actually better since i put a magnaflow muffler on it.
