FORUM GODFATHER.....R.I.P. PAT
I just checked mine for the fourth time at 48,000 miles and nothing moved. In those four checks, the only change was an exhaust valve that closed by .001" on the third check. I'm getting real tired of doing checks so I did what I should have done the first time and got all the clearances between midpoint and maximum. As long as the engine runs okay, I'm never taking the valve covers off again.
