There prob a proper stuff think in the Limbach manual but if in doubt a product called proseal 10 to 1 is its mixing. It is ideally for fuel tanks (offer used in Tiger moths) & works work with oil. Expensive & LAME will always have same but I buy from aircraft spruce. eg if you ever get a crack & oil leak in rear RHS lower L2000 engine it will fix it. I cast an aluminium bung & it gets led in with say 3mm thick proseal. Deacon or JB weld metal epoxy is useless trust me.
Years ago we had a NZ wing tip tank Pawnee. It would always crack tanks each 2 years but proseal over joins after welding it never ever leaked again Guess bit off the topic.
