Hi all, due to to low oil pressure and while the sump was off for a leak I thought I would replace the con rod big end bearings. I expected to find STD stamped or an over size. I have 307715 and VP in a circle followed by 4166 would this indicate a size please. Dave

Hello Dave,

the standard bearings are not stamped as such, only under size, eg 010, 020 etc. If there is no such mark they are standard.

Thanks for taking to time to reply, that was my guess but confirmation is nice to have
