copper gasket? never saw evidence of a paper one failing or blocking the flow of oil. somebody is a little OCD here. cant re use a copper one without re heat treating it.

I will pass on another tip the WW-II Instructor (Chief Mechanic at my Uncle's Pontiac Dealership) showed me years ago.

Sometimes, when you are drilling with a small drill bit, the drill bit breaks into two pieces. The overall length on most drills (even small diameter drills) is over 2.0" long.

So I was going to braze up a pick-up on a new oil pump for a Pontiac Engine and he explained there was a better way and no harm would come to the pump with his method. You could also use this method if you did not have a Gas Torch or welded available available.

So what he did was:

a) Carefully drill a hole thru the soft cast iron oil pump pickup boss with a drill slightly smaller vs the broken drill he had available. Clear the drill shavings.

b) The drill needs to enter and exit both sides of the Oil Pump boss.

c) Install the oil pick-up screen to the oil pump in the proper location.

d) Now using the hole previously drilled in the boss as a guide, drill thru one side of the oil pump boss, then thru both sides of the pick-up screen tube, and finally thru the other side of the oil pump boss. Drill slowly and carefully.

e) Install a small drill thru the 4 holes and get a total length for a retention pin (broken drill bit).

f) Trim the broken drill bit to the same length as the outside diameter of the pump boss minus .060" and then tap the broken drill bit into the 4 holes.

g) Take a small Ball Pean Hammer and using the ball end "trap" the broken drill bit inside the boss on each side by peaning the cast iron over the drilled outside holes.

NOW THE PICK-UP TUBE IS SECURED SO IT WILL NEVER FALL OUT FROM VIBRATION, YOU DID NOT NEED A TORCH, YOU DID NOT NEED A ARC WELDER, OR EVEN ELECTRICITY. A simple drill set, a 3 Jaw "Hand Brace"
and a little muscle and the oil pump is ready to go back on the engine. It will never come out again.
