Viggen better lubrication
Higher revs and raw power demand better lubrication than stock.
What can be done for a Viggen for better lubrication? My mechanic advised for something like "delete balance shaft or chain" (I didn`t fully followed).
Beside using Mobil 1 0W 40 fully syntetic oil, I really don`t know what else to do.
As usually, your expertize is greatefully awaited.
P.S. Yeah, it was not my pistons, it was a bearing from the crakshaft, lacking a proper lubrication. Damn! I almost focked my whole engine block!
