What controls oil pressure in a 3.9L 1994 Dokata? After having the oil changed the oil filter cartridge was balloned out. I've been having problems with low or zero oil pressure. At first the delership said it was sludge build-up. Now I'm not too sure. It has 120K miles on the engine. I've put a new oil sending unit on with a mechanical gauge teed into the unit. Going down the freeway @ 55 mph, I noticed the gauge read 0 psi,and the light came on shortly.Having no place to pull over,I continued home (about 20 miles). No knocking, or rod knock,but I am concerned that this could happen again. Oil level OK. What's wrong????
