My wife recently inherited a 2002 Taurus (Duratec) from her grandparents. It has various issues that I'm trying to diagnose and (hopefully) fix. The big one that I took care of yesterday was replacing the PCV elbow that had a hole in it and had collapsed. That seems to have solved the majority of the issues that she noticed while trying to drive it. I know there are other things wrong, but I'm not sure how to go about diagnosing things. Below is a list of what I've observed up to now.
- Slow leak in both power steering and brake systems (I will occasionally need to top off both fluid reservoirs).
- Some sort of issue with coolant system (dash light indicating low coolant turned on at one point). I can see evidence of coolant in the engine bay around the reservoir, but I'm not entirely certain that isn't from spillage while topping off the reservoir.
- Substantial amount of oil in various parts of the engine bay. There's spray/splatter near where the PCV elbow is that is clearly from the old elbow having a hole in it. There's also quite a bit covering the left side of the engine bay (where the serpentine belt and various pulleys/pumps are). I'm not sure if this is also due to the PCV elbow issue, or if it's coming from somewhere else. I'm pretty sure it's oil, but I suppose it could be another fluid.
- I noticed the transmission fluid dipstick was partially popped out of place. I'm not sure if this is because someone simply forgot to put it back all the way, or if something caused it to pop out.
