1952 A7 oil to rocker box

Hi Anji,
I am a fan of converting to the A65 system where the ball sits against the back of the oilpump
Since the engine will be fully stripped down its an easy job, You need to take extra care with the pump gasket so it does not interfere with the ball seating on the pump face

G'day Anji.
Bugga! You can buy new ball & spring. Re seat the ball (I get two balls ( ) and use one to re seat (then throw away) and the other to use. You may need to run a drill down the hole to clean the seat just a tad, and then just a light tap on the disposable ball to seat it.
As usual a $2 part failure causes $1000 damage.
Cheers

Hi Muskrat
Thanks for feedback. Not really looking forward to redo the whole fricking lot. Will take your advice on the seating. Camshaft was dry. Only ran the engine for maybe 4to 5 minutes. Still don't understand how oil was returning to the tank.
Thanks & cheers

Hi John
Thanks for feedback. Not quite sure what you mean having never been inside a A65, John.

The A65 ball and spring fit from the oil pump side rather than from inside the crankcase making it easy to get at and easy to reseat the ball on the oil pump.

SRM end feed converted engines have the ball and valve fitted this way.
