JohnD Posted January 10, 2018 Share Posted January 10, 2018 The "Wet" test will not raise compression if there is a valve fault, so no sign of that.Dry 115 105 110 95 105 110Wet 150 130 130 125 125 125Diff _35 _25 _20 _30 _20 _15As you can see the increases are about the same. Ideally all compressions should be the same across the block. That you have a range of 20 and one outlier at No.4 is probaly just a slightly worn engine.I'd do nothing, but go out and enjoy your Triumph!John Quote Link to comment Share on other sites More sharing options...
