Life of a noob. lol but on a real, safc is still been use on 4g63 engines? I see them alot on sr20 but most 4g owner I see in Jamaica use evo 8 ecu with tephra v7
When I did my evo 9 cover, I use a saw and cut off the nipple then drill a hole to an10 then force/screw a copper an10 bolt in it to create threading. After that I had to wash it in gas over and over to get the cuttings out
The same thing happen to me when one of my injector stuck open and the engine hydro locked. I just clean the injector and change two bend valves and it was good to go.
