so i have this set up for abut 6 mont now ran into a prob like a week ago ater rasing one night and d motor started to idle really low to d point where my oil light would come on so i check oil its fine i did com test and it turned out one off my pistons is lossing com its like 110 where other pistons are like 190 so i put some oil directly into d low comp piston trough d spark plug hole and it went up to like 180 so i m just wondering what u guys think its wrong is it piston rings head gasket or bent valve before i start taking it apart and its not burning oil

 

Since the oil helped it's more likely in the bottom end. Any modifications we should know about?

 

no its all stok but im thinking off building it but cant find pistons for f23
