I had saved the oil filter (ACDelco) that was on the vehicle when the oil light had come on and opened it up for inspection. This revealed at least a tablespoon of brown shellac appearing particles in the remaining oil in the canister and the pleats of the filter were at least partially clogged with the same material. I did not find any metal material of any kind. I also did this on the last new filter (Napa Gold) that was installed after the flush and run for approximately 1200 miles before I changed it and the oil again. There was some of the same particles in the filter pleats and cannister, but not nearly so much as before. I replaced the Napa Gold oil filter with a Pennzoil oil filter and had driven the car approx. 500 mi. When the clatter started again at idle followed by the oil light coming on at hwy speed. I had the oil and filter changed again (Motorcraft oil filter) and after driving for less than 50 miles, same thing happened again, except the oil light went off and clatter stopped when not at idle. The Pennzoil filter that was last removed is partially clogged and there is a small amount of the same brown shellac materiial in the cannister. Any ideas where the material is coming from and what to do about this problem?
(Please note: the quality of the three brands of oil filters mentioned above are of varying quality of construction, the Napa Gold being by far the best of the three [akin to aviation quality ones] followed in order by the ACDelco and Pennzoil ones, both of poor quality, IMO. I have not yet removed and inspected the Motorcraft one.) [Code:1:3d4a0fa42b][/code:1:3d4a0fa42b]
