I found a beautiful 1984 500 SEC about 6 months ago. Had 230,000 on it. And everything works! Even the rear defroster. No tears or wear spots on the leather.
Anyway, at startup after setting a while there is a definate ticking more noticibly on the passenger side front cylinder. I put Mobil 1 15/50 in it about 3000 miles ago. Still no change. Just last night I read here Mobil 1 could take 10,000 miles to quiet down the lifters. Keep you posted.
