Project escort, removed pistons and found some marks like valves had given them a kiss, 1 i could understand but all 4???
start with the head,
Bit dirty but no damage


Pistons after a clean-up with some neat petrol





All 4 marked in same place, no damage to head..... Has it had a snap and been revalved??????!!!!!!! Definatly not ment to be like that unleas they mchined them with a hammer and chisel because they are definatly knocked!!
Any ideas?? The valves are undamaged and the marks on pistons were all mucked up so guessing not recent, im pretty stumped as could be a number of wrong doings, head skim, gasket, wrong lift clearence, wrong pistons, wrong valves at some time.... Any ideas??
