I purchased the car off my brother (who put the exhaust on). He said that he knew exactly what the problem was. There is one bracket that is very hard to get to that has came loose. It causes a slight hole where the leak is, and also the rattle. The guy that told me the mounts were shot seemed like he may have been just trying to get me to leave cause he didnt want to mess with it. I looked at the motor today as it was being cranked and also revved up, not very much movement at all. The mechanic I had look at it couldnt even find the rear o2 sensors, so I am beginning to think I have been mislead and misinformed, and that nothing is wrong besides the very small leak. I also mentioned a lean condition possibly caused by the leak. A friend (just got out of college studying the 4.6 ford motors) said that the MAF meter is a little larger than stock, causing the lean condition and that there is nothing to worry about. I am gonna have him take a look at the motor and mounts and go from there. I am all about saving money (gonna try to do some touch up painting, and mystic isnt cheap), so I dont wanna do a bunch of stuff that will have no effect. Thanks everyone.
