I have a 2000 Mustang with the 3.8l V6 with around 150k on it. When I parked it, it seemed to be periodically losing oil pressure. I first assumed that it may be the sending unit until the lifters started rattling really bad and the engine started smoking. It would smoke fairly bad when it was first started, very similar to bad valve seals. The smoking, like the oil pressure is not consistent. The last several times I have started the engine the oil pressure was good, according to the factory gauge, no rattling up top, and no smoke. Also the camshaft synchronizer had just started making a squeaking sound that was also intermittent. So, other than needing a new camshaft synchronizer, I’m thinking maybe the screen in the oil pan is clogged? Any ideas? Also does anyone know it the motor can be jacked up and the oil pan removed without pulling the engine? Any help you could provide would be great!
