Can someone tell me the size or what they use to remove the distributor oiler plug on a 350 olds ? I had a ground down bolt that worked in the past but this plug is in there tight and I don’t want to round it out. Thank you

 

Go to Napa and get a S-5/16 cr-v made by Carlyle. It is an inverted tool you use with a 3/8 drive ratchet.
Part # I believe is S38SQDP10 If my eyes didn't deceive me like they sometimes do...

 

Thank you : you got the number right but they don’t stock them would have to order but at least now I know what to look for
