Just finished doing the three year maintenance on my GTs, and have found some items to relay that I don't recall being discussed.
AIR FILTERS - My original air filters were made with orange rubber and very substantial. The filter elements ran lengthwise, and code number on the filters is XL3U 9601-AC-RR. The replacement filters purchased from Ford use black rubber with the filter elements running widthwise. Code number is XL3Z 9601-AA. These new elements are not as substantial as the original ones that came with my cars. Remember we did have a forum member that had his throttle stick open when a filter came apart and lodged into the throttlebody. These new black filters did have dripping black plastic in excess when molded.
OIL PUMP - On my heritage I found a slight oil leak and traced it to the shaft that comes out of the oil pump. There is a seal that is supposed to keep the oil in the oil pump. This seal is not available as of yet. To fix this problem the oil pump has to be replaced. At a cost of about $1500 for the pump alone, a seal replacement hopefully will be found. A handful of these pumps have been replaced already due to this seal leaking.
ALUMINUM THRESHOLD STRIP - The polished aluminum strip that you have to crawl over when getting in or out of your GT, gets scratched very easily. I have found that Mothers Mag and Aluminum cleaner will take the scratches out and make it look like new.
TIRES - If you are running Hoosiers, please remember that these are race tires and as such lose air. I didn't run my car for a couple of months and the tire pressure went from 28 to 15-18 lbs per tire. All four lost air and was told that this is normal.
Hope that this information is helpful. It is just a partial payback for all of the great information I have received from our Forum brothers and sisters.
