Watch how quickly the oil turns dark.Sounds like you've got a sticky lifter.

Monitor what the oil and sludge look like inside the valve cover through the filler hole. It will melt away......

Good advice ^^

The only thing I could add would be to use a Motorcraft FL-300 oil filter during the clean-out. They're relatively cheap compared to the Wix 51085 filters and wouldn't hurt to replace the filter once or twice during the clean-out process, adding back the lost T3 at the filter changes.

Run it for 1000 miles and look at the progress. Change just the filter and add more t3 to it. Keep on monitoring it.It ain't gonna hurt anything leaving it in.
