CHECK CLEARANCES OF TAPPETS WHEN COLD.. INLET IS 0.10MM AND EXHAUST IS 0.25MM.. THESE ARE FOR 1992 1.4 RT. E SERIES ENGINE. ALSO CHECK YOUR OIL LEVEL AND CHECK THE QUALITY OF YOUR OIL.IF ITS WATERY AND BLACK , DO AN OIL AND FILTER CHANGE. THE TAPPETS RELY ON A GOOD VISCOSITY OF OIL TO LUBRICATE AND CUSHION IMPACT WHEN IN USE...HAVE DONE ALL THIS TODAY ON MY OLD J REG CLIO AND THE ENGINE SOUNDS BRAND NEW... HOPE THIS HELPS....
