OK, I know, I've been here before; some people never learn. Last couple years I was busy remodeling, then two grandsons born 2K mi. & 6K mi. away. So my 40 y.o. A4 reminds me about the true cost of neglect. Picture the corroded valve seats and ex.manifold, and its stud. New valves, keepers, washers and assorted gaskets should arrive from M.M. tomorrow. Question is, should I just 'lap the hell out of it' as my machinist neighbor said last go 'round? Or is it time to face the music, pull the engine, and have the machine shop regrind the seat in 'proper' fashion? And only two studs came free when I pulled the head; the corroded back manifold stud (top) did not. I'm inclined to give the in-the-boat DIY another go, but I'm open to suggestions from wiser folk than I. Thank you.
