1995-2002 Range Rover Classic
if you're worried about oil pressure, first look at the age of the engine. if satisfied with wear and tear due to normal use, contact mark at aluminum v8 dot com. he has an early v8 pressure upgrade kit as well as remote filter relocation and oil cooler kits.I'm under the impression that the 3.5 oil pump is barely adequate. I'm preparing for some desert camping and i'm looking into fitting an oil cooler. I know later classics came equipped from factory with a cooler, but I am concerned about pressure. What do you think?
the first time I used one of their pump kits I had a constant 60 psi at idle, cold on a rebuilt 3.5 engine.
the later classics you mention were equipped with the 3.9, you can use/retrofit those 3.9 components on the 3.5. direct fit.
