High Mileage EA motor teardown, 330,000 miles + Options

[mgphoto]

The time has come to rebuild the original EA motor in my '72.

I am most of the way though teardown, I will add some photos of the worn parts in a later post.

I am trying to figure out the size of the tool to use to remove this fastener, the cover for the second oil pressure relief piston and spring.



Factory service manual has it as M14 internal head socket. I searched for it but all I could find is the AST Tool # S 54 X-14 at the link listed below

Does anyone know if this is the correct tool?

Thanks for looking,
Mike

I took the case over to Engine Machine Services, they cleaned it and they measured it today, Bruce said the case is used but not worn, woo who.....

He also said that after cleaning, the case is a bit stained, so I will have to look at it to see it I want it bead blasted, any advice here???

Worst of the damage was the valves stuck in the retainers, a brass mallet and a little pressure on the retainer freed them up.
Also one of the pushrods had contacted the pushrod tube retaining wire and wore the pushrod slightly, (my fault, I fiddled with the rocker arm to determine usage of 911 adjusters and installed the wire incorrectly.)


OK so here are some photos of the internals.

1st the worst of the bearing,
Cam bearing center position


The forward exhaust valves have white deposits while the rears where a bit black and oily.




OK top ring gap!




more to come!
