This was my sons jeep and I just acquired it from him. I am repairing it and upgrading as I go. The last older used vehicle I had took a lot of cleaning to get the engine up to where I wanted it. The engine has valve noise that dropped by half after this cleaning and before I go full synthetic I would like it cleaner. The 2 piece pan would facilitate that long term. Besides it is a Jeep and half the stuff we do does not make sense.
