1989 Ford Mustang GT Drop in Oil Pressure gage
\015 My oil pressure gage keeps going high and low when changing gears. It will have no pressure what so ever especially after 3rd gear.\015
I hate be the bearer of bad news but it sounds like you bottom end bearings are getting worn out. You have excessive bearing clearances causing your drop in oil pressure.
