Question about 2005 Jeep Grand Cherokee
I have a 05 Jeep Grand Cherokee 4.7 engine. This past Sunday I started it up and it was really loud, then there was this ticking/tapping noise. It sounds awful when you drive off but after a couple of minutes, the noise goes away. It seems to only do it when the engine is ''cold''
I had what sounds like the exact same problem. It was an exhaust leak from the left (driver's) side exhaust manifold. This engine has a history of the manifold bolts breaking and causing the exhaust leak. The engine is also used on some Dodge vehicles. It sounds like a tick and I almost mistook it for a bad lifter. I took it to the local Jeep dealer who confirmed the exhaust leak. I replaced the left manifold completely and replaced bolts/gaskets on both sides (left/right) and it fixed the problem. Be careful, as the dealer tried to gouge me on the price. You are looking in the ball park of $600 parts/labor. I got parts for $120 and it took the better part of a work day to do the job.
