Hi i have some questions, for you guys is it possible to put the main bearing bridge og another block? or does it have to go with the one it was originally installed on?

another question, look at the picture i've attached, two of my pistons look this way.. a little tip os the edge have been bent inwards? problably cause of pre-ignition.. can i use this piston again? my engine broke a cylinder sleeve on cylinder 1. Piston 1 and 4 looks like this. Think it has been running with this damage for a long while..


regards

by the way, the connecting rod, ang piston skirt looks good
