Replacing oil Gallery plugs Chevrolet??

[Phil Waterman]

Hi Alex


What is throwing me is your first picture with four of the small drive fit plugs and four of the threaded plugs.


I've confirmed that the threaded plugs are for the later engines my 261 has them while the 235 has the drive fit plugs. So we're OK there.


What I am not figuring is that I can only find two locations for the oil line plugs on the manifold side of the engine the long passage for the cam bearings that runs from front of the engine all the way to back.


Check several different vintages of CMP manuals and parts book and I can only find where those two plugs are used. So I'm at a loss as to why the kit includes 4 of each type.


Cheers Phil
