We have a problem with our 1997 Ford Explorer. The oil gauge suddenly drops to zero pressure when we make a right had turn, and the check gauge light comes on. When I straighten the vehicle out it goes back to normal. There is no problem with it when I start it or when it is running on the highway, just when I turn right.
Lately it has developled a rattling noise, which I have been told is a sticky tappet..
thanks for your help.
