Have any of you ever experienced this problem?
About a year and half ago I rebuilt the engine of my 65 beetle (first time). Within the past several months I noticed that my valves have been tightening up before I reach the 3000 interval mark for my next value adjust.
However, within the past month the problem has becoming progressively worse, to the point where I can no longer adjust out my valves for the 1,2, and 3 cylinders. Basically I can no longer get my feeler gage in between the adjustment stud and the end of my valve stem.
Is it possible that my valve seats have moved? These are rebuilt heads with only 10,000 miles on them. What gives? Any insight in this area would be much appreciated.
