Well, I said to pay close attention to cyl. #2 and there you go. It's almost always #2 but sometimes #3. If I'm right, one of the exhaust valves has beaten the valve seat to death. Do a leakdown test to verify the pressure loss is from the exhaust. If it is you'll need to remove the head and inspect the valves/seats. If you find wear/damage, cylinder head replacement is your only repair option, AFAIK. The after-market may have a cheaper repair solution???

Well ... thank your for the insight. I'm now thinking about how to proceed. The leak down test is beyond my capability. Do you know of any indy shop in DFW area ?
