1995 Windstar Oil Pump Removal

I joined this forum today hoping to get an answer to my mother's 95 Windstar Oil Pump problem. I performed a search in this 2CARSPROS FORUM for my problem and 2 other people asked the same question in 2009 and 2010 with no replies? Why are there no reponses or am I looking in the wrong place? I have a FORD Chilton Windstar Manual (26840) 1995 to 2003 and it leaves allot to be desired for the 3.8 Liter 1995 model for the oil pump removal. I have never worked on a front wheel drive vehicle before and to tell you the truth I don't ever want to work on another one after this one (Mothers Van). However I need help on removal of the upper right bolt (10mm) on the oil pump. I have figured out how to remove all bolting except this one. I removed the serpentine belt and alternator to gain better access to the bolting (10mm and 8mm). Next I removed the AC Compressor bolting (4) thinking I might be able to access the upper right oil pump bolt by moving the compressor with lines intact, only to find there is a curved shield plate behind the compressor. The power steering pump is mounted directly above the AC Compressor. I will try and re-examine the obstructing plate issue this morning. Hopefully some one in this forum has done this before and can help. After I figure out how to remove this last bolt, I will be removing the oil pan next. The Chilton manual states the "Y" pipe exhaust and starter needs to be removed, I can't wait to tackle the exhaust manifold bolting. Any guidance would greatly be appreciated. I failed to mention that the engine was completely re-built 2 years ago (Aprox 40,000mi on Engine). The oil idiot light on the dash was flashing (Fluttering) indicating low oil pressure. The oil level was checked and the level was right at the full line (Color Light Brown) and there is a knocking noise on the top front right side under the Air Intake Plenum with the engine running at idle. Sounds like one of the hydraulic lifters. After I inspect/repair oil pump/oil pickup tube/oil pump intermidiate shaft, my thoughts were to try some Seafoam (1/3 of Can in Each Area) in the oil, fuel and PVC vacuum line (Clean Lifters) at 2000 to 2500rpm. Some of my research with Seafoam usage indicated to slowly inject into vacuum line off off Master Cylinder, however not all Intake and Exhaust valves are affected going through this vacuum line. Again all comments are welcomed. I have taken pictures of everthing, as I do with all auto repairs I perform.
Thanks
