Reading on an rx7 forum I've learned that there are multiple options for the= turbo oil drain on an NA engine.


  1. I can   weld a bun= g into the oil pan

Has anybody used the OMP block-off-plate drain idea w= ith any success?
Should I just put my big-boy pants on and take the front= cover off and either switch the front cover or drill/tap or tig a bung to t= he lower section of the front cover well below the OMP pad?


Advic= e sought.
