Default Cracked Upper Plenum
while installing my AAM plenum spacer....my upper plenum crack as i was bolting things back together(probably due to over torching the bolts)

the crack isnt deep but its about 1.5inches wide and just breaches the upper surface of the plenum.



is it okay to drive?
any suggestions?
please help
thanks

EDIT***
i feel air being sucked in from the crack when i rev the engine....GG on me.

The crack will get bigger because of engine vibration. Check the marketplace for a used plenum.

Sure welding aluminum is not big task, just have to have the correct setup, learned this on my 240Z, they have a aluminum head,
