For threading light alloy you don't need to spend big bucks on a machinist-quality tap, just get something better than cheapo Chinese.

Do you have the ¼NPT tap for the oil pump passage? That'd be their #55284 or
Note that when plugging the pump's outlet you often will need to grind the tap shorter so it'll make threads of sufficient diameter before bottoming out against something...a similar problem may be encountered when tapping the case, if you force a bottomed tap it can crack the case - drill deeper and/or shorten the tap.

It doesn't take much tap to make nice threads in your target material. Nor does one feel bad about shorting inexpensive taps.
