The 4.7L V8 which Chrysler designed and put into Jeeps and Dodges in the early 2000's is a great motor. Very reliable, long lasting, and a reasonable amount of power and torque. All that said there are a few fatal flaws inherent in the design of this motor. Thankfully, you can do something about it.

In this video I am removing and replacing the valve cover gasket on my 2001 Jeep Grand Cherokee with the 4.7 V8 because it has been leaking oil. With the valve covers are off, I am going to take the time to replace the hydraulic lifters (lash adjusters) which now have 125,000 miles on them. These lifters tend to wear out over time or if the engine has had regular oil service neglected and can cause catastrophic engine failure if they collapse fully.

This process will be the same for all Jeep Grand Cherokees 99-04

It will also be extremely similar for Jeep Grand Cherokees 05-10, Jeep Commanders, Dodge Dakotas, and Dodge Durangos with the 4.7L. The different on these vehicles may be in what has to be moved to get to the valve covers. Removing the rocker arms to access the hydraulic lifters will be the same.

Though this is not a quick or easy repair, I have some great tips and tricks so that any DIY guy in the garage can get this done on their Dodge truck or Jeep.
