Since I had the valve cover off to do the PHH, I decided to check the valve clearances. I had 2 exhaust and 2 intake that were right at the large end of spec, and one intake and one exhaust that might be a thousandth over. This is using feeler gauges, with slight drag/resistence indicating proper measurement. I can live with 2 that are a thousandth over. I'll check again in 20K. Or when the nightmare of the PHH has faded into the oblivion of my memory. Rig has 75K miles, FWIW.
