dismental my engine yesterday, but found only now i realise that the piston pin (the 2 clip that secure the piston) is very different from OS, as in OS, there is a tiny bent bit where u can pull the clip out. At 1st i thought it was broken, thereby causing my engine to have few scratches on the piston wall. but then i check again, it seems that both sides are the same. so my question is how are we suppose to remove the clips to replace the conrod?
